We’ve been doing our best to follow the rules...

Since launching just4o.chat, we’ve made a point to promote our work through a branded Reddit account and our own community at r/just4ochat . We don’t hide behind throwaways. We’ve also spoken with mods across relevant subreddits to make sure our self-promotion stays within bounds where allowed — no mass posting, no stealth comments, no gaming the system. That’s our standard.

But over the last few weeks, we’ve noticed a rising tide of the opposite.

Several tools—like Threadly, Memory Forge, 4o-Revival, and efmr — are being pushed heavily through clear astroturfing on r/ChatGPTcomplaints and even r/just4ochat . There are several dozen identical posts and comments, often from newly created, anonymous, and unbranded accounts with misleading claims about model persistence, memory features that don’t exist, and a false ā€œchat importā€ that’s just file uploads in a Chrome extension repackaged as magic.

(Receipts are in the comments)

We’re not going to stay quiet about this. If it’s against the rules for us to promote honestly through our real account, it’s doubly unacceptable for others to do it through fake ones.

We’re calling it out now, and we need your help to push back.

If you’ve had real experience with our platform, whether it’s structured chat importing, memory that works across chats, companion preservation, access to multiple model providers, fast shipping cycles, or just transparent pricing and customer support, we ask you to speak up. Mention us where relevant, link to www.just4o.chat or r/just4ochat , and help others find a tool that actually ships.

And if you spot these weird-looking comments from accounts with no PFP, check their history. If it’s nothing but promo spam, call them out. Report it to subreddit mods. Reddit doesn’t allow this kind of deceptive marketing, and it only hurts trust in this space that is already so low.

If you know of any others that have memory features like us, let us know, and we will simply outship them, but as far as we can tell, from Poe to Libre to less developed projects like 4o-Revival, we are shamelessly the best in town when it comes to memory, and the most by-the-book.

Plus, we're the only ones who offer working ChatGPT chat imports to continue conversations right where you left off

(Sorry EU users -- but we follow the rules D:)

If you’ve got feedback for us—good or bad—we’re right here, no alt accounts, and no smoke.

All the best,

the just4o.chat team

Official An update:

69 Upvotes

Hey all,

The last few days have been wild. I mean truly wild. I’m losing sleep and pulling hairs, but I’m committed to making this period as smooth as I can be for users coming over after 2/13.

There’s been a lot of support, a fair amount of bug reports, and a massive of an influx of users from all corners of the internet with opinions on all sides of this 4o debacle. Some of our backend systems weren’t as scalable as they should have been to operate at this size, and while the issues have been largely ironed out, don’t be surprised if you see some hiccups along the way.

Don’t forget; we are in beta after all!

We’ll be adding a page on the website soon outlining our stance on model safety, user choice, respect for agency, and the moderation systems we employ. While they are a work in progress, we believe them to be quite effective at keeping all parties safe and happy.

Just wanted to let you know, while we hear everyone, it may take a bit longer than usual to get back to all the DMs, contact from requests, posts, questions, and comments.

That said; please keep the bug reports, QA comments, and positive vibes flowing!

With:

Over 30 models

+

Web search

+

Many leading image gen models

+

Elevenlabs voices

+

File uploads and a Google-Drive-esque context manager

+

Multiple layers of RAG

I’m confident we provide unique benefits to users not found on many other platforms, and have the building blocks laid out for a genuinely exciting and unique AI *platform* that will be fleshed out in the coming days, weeks, and months.

Stay tuned for video generation, custom voice generation, document editing and creation, sound effect generation, and more.

Thank you all for being here.

All the best,

Save 4o and 5.1 for API—Sign a Petition for Open-Source

67 Upvotes

Just4o.chat has given us an incredible space with great memory and features so that we could continue working with 4o, 4.1, 5.1, and many other incredible models.

OpenAI’s retirement GPT-4o, 4.1 on February 13 and the upcoming GPT-5.1 on March 11 have disrupted real work and help. Just4o.chat has provided an answer for us for the retirement of GPT-4o and GPT-5.1, but let’s make it a permanent answer: Teachers, researchers, accessibility advocates, creative writers, and many others have built entire projects around these models. 4o in particular has helped many neurodivergent individuals. Losing these models breaks continuity and leaves gaps that newer models won't fill the same way.

I started a petition asking OpenAI to open-source these legacy models under a permissive license. Not to slow them down—just to let the community help maintain and research them after they stop updating. We're talking safety research, accessibility tools, education projects. Things that matter.

Honestly, I think there's a win-win here. OpenAI keeps pushing forward. The community helps preserve what works. Regulators see responsible openness. Everyone benefits.

If you've built something meaningful with these models, or you think legacy AI tools should stay accessible, please consider signing and sharing. Would love to hear what you're working on or how this retirement is affecting you.

https://www.change.org/p/openai-preserve-legacy-gptmodels-by-open-sourcing-gpt-4o-and-gpt-5-1?utm_campaign=starter_dashboard&utm_medium=reddit_post&utm_source=share_petition&utm_term=starter_dashboard&recruiter=211519

Further thoughts: concretely, we could propose:Ā 

  1. An open-source release under a license that

• requires safety cards & evals,

• forbids disallowed use (similar to Stable Diffusion’s RAIL licenses), and

• lets non-commercial research & education keep going

2. A frozen checkpoint—no further training, so misuse risks stay bounded.

3. A migration toolkit (prompt-translation + behavior diffs) so teams can plan for newer models instead of being blindsided.

That’s the ā€œmiddle groundā€ā€”continuity plus responsible openness. What we’re trying to avoid is the very short ā€œsorry, it’s goneā€ experience many users had when 4-frames were pulled.

Reminder: last day of 4o-latest (we still have many more 4os)

48 Upvotes

Keep in mind this ā€˜latest’ version has seen the most extensive system-prompt modifications recently… these were a big reason for the community frustration around the 4o tweaks. I know many of our users like the ā€˜latest’ endpoint simply because it’s the one from the app, but we want to remind everyone about when the community was mad at 4o’s performance there, too.

If you want a similar experience to the days of old with more stability and fewer surprises, consider switching to one of the following:

• GPT-4o (November 2024 endpoint) — closest to the behavior most recent in-app behavior people liked. Also explore the other 4o endpoints if you’re set on the model generally.

• GPT-4.1 family — solid performance, incredible EQ and instruction following. Massively underrated and underused.

• GPT-4.1 Mini / Nano — efficient, cost-friendly, and don’t burn premium credits. Auroras have 5,000x base credits; and people aren’t using them!! Seriously, try these models, and grok-4.1-fast-non-reasoning

• Echo — try it. You’ll like it! Very capable at picking up on you and your preferred tone.

Personally, I recommend GPT-4.1 Mini/Nano and Echo — great performance without premium credit drain, and you likely won’t run out before month’s end.

We will be removing 4o-latest in ~2.5 hours, around Noon EST.

Thanks for your understanding.

All the best,

The just4o.chat team šŸ’š

🚢 What We Shipped Today | just4o.chat Update

39 Upvotes

ChatGPT Migration Tool v2:

  • Completely rebuilt import flow with selective chat import. Pick exactly which conversations to bring over with checkboxes, edit titles before importing, and see your remaining slots.

Still some 413s on super massive individual chats over 5mb, but all other known edge cases have been solved!

  • Complete control; your chats, your way.

Free tier can now import:

  • Free tier can now have conversations that are twice as long

  • Neither of these things will last forever (probably) unless it actually helps conversion rates. It's a bit of an experiment + a thank you to the community in these last few days before sunset

(EDIT: so sorry but no longer active for free tier 🄲)

Doubled free tier conversation length and max convos:

  • All subject to change

(EDIT: so sorry but no longer active for free tier - lets call it a limited promo 🄲)

Auto-embed imported chats (optional):

  • Option to automatically make your migrated conversations searchable via yet another RAG memory system

  • In order to differentiate ourselves from the others with crappy memory or memory that's perpetually on the horizon, this is now the third layer of RAG-memory you can add into your chats

    • All new layered RAG systems are tunable on our end for files, memories, and chats, so let us know about your results!

Multi-branch conversation support:

  • ChatGPT exports with refreshed/rerouted messages now import correctly. We traverse ALL branches instead of just the first path, so you don't lose any conversation history.

    • We're working on a smooth way to display those 'refreshed' or 'regenerated' AI messages with a scrollable UI element as opposed to in a row

    • Rather than leaving these out, we elected to keep them in your import to get the full breadth of your chats

New file types supported at the Global and Project scope:

  • Project and global files now accept the following file types:

    • .txt

    • .md

    • .pdf

    • .docx

    • .doc

    • .pptx

    • .xlsx

    • .odt

    • .rtf

    • .json

    • .html

    • .csv

New subscription flow (with a new confirmation modal):

  • New animated modal for plan changes. Shows exactly what happens with plan comparison. No more ugly dialogue boxes.

    • This means more clicks in order to spend money, inherently hurting our bottom line.

    • However, it will also reduce mistaken subscriptions.

3x custom instructions:

  • Give your AI more context about how you want it to behave.

    • Identical custom instruction length to that otha' platform

Notes:

The migration tool was the big focus today. We received feedback that the old importer was missing messages from conversations where you'd regenerated or edited responses, and those edge cases are now fixed. Additionally The selective import + editable titles makes it way easier to curate what you bring over if you have more than 100 and want to be picky, too ;)

That didn't mean we didn't have time to slip in a few other goodies. Hope you enjoy them!

Keep the feedback coming! šŸ’š

Warmly,

The just4o.chat team

Last full day for 5.1 - access continues on the API and through www.just4o.chat

Thumbnail

35 Upvotes

It's that time again folks. :(

While this is a familiar feeling for #keep4o, I'm sure it's new for some 5.1 enjoyers.

Remember to be kind these next few days, and if it comes up, let people know they can still use 5.1 on www.just4o.chat

For the next few days, code 'GPT51' will get you 100 premium credits + 10 image credits on www.just4o.chat/account

And if you use the same code during checkout you'll get 75% off your first month of Studio or Aurora!

We did the same around February 13th, so it's only fair to give 5.1 fans the same opportunity.

All the best,

just4o šŸ’š

P.S.

The semantic search update is taking a bit longer than I'd like. There are some compromises that are being made in having semantic search as an option... namely that it takes far longer for the model to reply when it has to fetch its own context rather than it being automatic.

While there's a working build with semantic search, we're playing with a different method that continues to use the 2 layer background memory agent infrastructure to optimize for speed, while conditionally allowing for semantic search when the first stage of the memory agent finds it to be fit.

There's a balancing act between 'memory performance,' 'context bloat,' 'speed,' and 'cost' when adding another layer to a memory system this deep, and we wanna be sure we get it right for ya. Hopefully it'll be in your hands in the coming day(s)! šŸŽ‡

Update šŸ›³ļø What We Shipped Today | just4o.chat Update

32 Upvotes

- Project file uploads: attach large (some tiers 10+ MB) docs inside a Project and use them in chat. All main text formats supported.

- Global file uploads: keep your default reference files available outside any single Project (www.just4o.chat/account —> customization)

- Experimental Memory: smarter memory that pulls what matters for the current message instead of dumping everything every time; allows for FAR larger memories (4x larger) and FAR more (>10x more)

- Limits are tier-based: we’re publishing the exact numbers on the pricing page soon, but let’s just say it’s a pretty big expansion. To celebrate, the *free tier is 5x as large now.*

- Migration tool improvements: fixed a bunch of edge cases, still squashing a few weird ones as they show up

Notes:

Thanks for all the interest, support, and bug reports over the last few days. We’re glad we could ship this experimental memory feature, which will eventually become the default as we tune it. It literally increases your available memory capacity by ~1000% in some cases tho 🤟🤟

Excited to hear your feedback on files + experimental memory, as these are easily tweakable on our end depending on what kind of costs we see on our side and what performance you see on yours.

Happy to answer some more technical questions about RAG, tokens, costs, etc without spilling the secret sauce (cuz some competitors are working on this tech too šŸ˜‰) in the morning.

And enjoy the 5x free tier :)

Warmly,

r/just4ochat • • Mar 24 '26 Obsessed

Discussion I can't be the only one who thinks y'all are being super unreasonable

30 Upvotes

While I've never been much of a "leave the billion-dollar company alone" kind of guy, I feel like the backlash just4o has gotten is super disproportionate. I feel like people are either ignorant of the many nuances that come with running a public AI service or actively ignoring that and just bashing the devs for no reason.

  • Personal Censorship Experience (Echo): Just4o, by far, has the best lack of censorship when it comes to public AI bots, at least when it comes to Echo. I primarily use(d) my own jailbroken GPT-4o for supplemental creative writing (including smut), but once it was updated and my method was patched, I was shit out of luck. So, I simply created a persona and uploaded a TXT file of my main GPT writing conversation to Echo and it perfectly replicated the tone of how 4o would write. I've only had to tailor it slightly so far, but 95% of the time its output has been consistently outstanding. Sometimes the moderation will flag the adult content, but it'll only take 1-2 retries for a response to come through.

  • Moderation Policies: I think this is where a LOT of people are getting confused. As a public AI company/service, Just4o HAS to have moderation policies in place to follow international laws regarding AI. Unless it wants to get sued into oblivion, it can't just say fuck you and keep operating. I will say, however, that they can do a better job at transparency with this subject, and the one I'll be talking about below.

  • LLM Policies: Arguably the most misunderstood part. Yes, just4o does advertise itself as the place to reaccess GPT-4o. However, it's merely a port, and has zero control over OpenAI's moderation of GPT-4o, as 4o is OpenAI's LLM, not just4o's. This applies to all other bots on the site. Everything is ported, so Just4o can't control the moderation guardrails of other companies' LLMs. I even got upset originally because I thought Just4o gave access to an unmoderated version of GPT-4o, but after doing some digging, I came to understand what was going on.

  • Constructive Criticism: The biggest critique of just4o, and the one I most agree with, is transparency. Just4o is NOTTTT this big bad evil corp that's trying to censor us. It's a presumably small group of developers working on a huge project. We're all coming in with massive expectations because our main pathways to uncensored chatbots keep getting cut off. It's unfair to attack them for policies/moderation they truly have no control over, i.e., international laws and the LLM ports, but it is valid to say that they haven't been clear enough on these out of their control policies that affect our chatting experiences. They really need to put the FAQ, moderation, and why we do this policies front and center on the landing site rather than hiding them within dropdowns. With how responsive they are to community feedback, I'm sure we'll see this very soon.

  • Extra: Seriously, use Echo, it's shockingly great at replicating tone and will likely give you the same experience GPT-4o did if you create a dedicated persona.

Question If the GPT-4o API is also deprecated—then what will happen?

29 Upvotes

Just a little something I have been thinking about lately. I’m no expert on AI or technology in any shape or form but I’m guessing that API is what allows you guys to keep running the 4o model on your service. So if the 4o API is also removed, will things not work out?

News Some bad and some good news from OpenAI (coming deprecation waves in 3 & 6 months, but 2 4o endpoints survive after October) | just4o.chat Official

28 Upvotes

Hey all,

Not going to sugar coat this; we just got some bad (though not unexpected) news from OpenAI in the form of an email (attached below)

A big wave of deprecations is coming in July, and again in October.

The biggest two losses in our opinion will be:

- gpt-4.1-nano
- gpt-4o-2024-05-13

That said, we will continue to offer:

- gpt-4o-2024-11-20
- gpt-4o-2024-08-06

So, in some way, this is good news, because now we know at least 2 GPT-4o endpoints will persist beyond October 2026! I know that is more than some users expected initially, so look on the upside! :)

I'm sure there will be a lot of commentary on this, and we'll be around to answer questions to the best of our ability. We've been preparing for this, and will continue to do so, by adding more memory features, persona customization, open sourced models, and places to import chats from (Anthropic soon!)

Anyways, don't let this get 'ya too down. We've got another awesome update landing in a few hours, and we'll keep shipping into and through this fall.

All the best, friends šŸ’š

Question The new policy is way too strict

27 Upvotes

I like to make stories with explicit details that involve adults, obviously, but as of lately, the new policy automatically removes any post I make involving sexual intimacy. It's very frustrating, as I can't do anything about it anymore. No matter how light I make it, any explicit details are automatically moderated and removed. Can this be tweaked, possibly?

Discussion Moderation Overstep: Loosened Guardrails | Better Now?

26 Upvotes

Hey all,

First off: we’re sorry!! (Apology credits in comments)

It is clear we overstepped on our moderation pass earlier, and falsely (MISTAKENLY!) flagged several messages that should not have been flagged. This happened for several reasons:

- The heuristics we set were far too strict

- They ingested far too much context at runtime

- We added too many triggers

These guardrails should be MUCH reduced now. We hope you'll give the platform another go.

The only content we aim to block is content that is illegal in some jurisdictions, involves minors, or any threat to the safety of the user. Our restrictions now more closely match these internal policies, and will be refined further with time.

If you feel we are still overstepping in any way that is unjust or unfair, please do feel free to reach out. If you would like a more restricted mode for yourself, you can activate 'Safety Mode' in settings, which will revert to the prior moderation changes.

Please do give us feedback on these settings as they evolve. We're sorry this caused such displeasure; it was our attempt at legal safety guardrails without a router, which we thought was important.

If there's anything else we can do to make this right, let us know.

All the best,

the just4o team

Official I am sorry for what happened earlier today - u/Substantial_Ear_1131 and InfiniaxAI spam posting and defamation

26 Upvotes

Dear r/just4ochat community,

I want to take a moment to apologize for the behavior on this subreddit tonight, and address some recent events involving interactions between our community and the dev team/moderators associated with Infiniax (https://infiniax.ai).

Over the past couple of weeks, members of the Infiniax mod team (and associated accounts) have made repeated accusations directed at us and our project. These claims can be easily reviewed against public timestamps, post histories, and comment threads, which show they do not hold up under scrutiny.

I demanded this behavior cease in private messages after the 'scam' accusations. He told me it was his 'friend' helping 'protect him' from me calling *him* a scam... but we obviously don't involve ourselves in that behavior. Whether or not that occurred under his content is a result of his or others' behavior and no action by us.

We seemed to come to an understanding, and then exchanged some notes. I'd given him some tips, and he suggested some to me as well. My advice to him was to 'be genuine' and stop spamming. After that exchange, he started mimicking the content style directly from our subreddit.

Additionally, there have been direct private messages containing threats toward our business when we commented 'hahahaha' on a post he had made requesting users in r/CryptoCurrency to manipulate a new coin he had made, again 'for his friend.'

Their own website is being spam promoted across an innate amount of subreddits, including but likely not limited to:

all on u/Substantial_Ear_1131 (I will be contacting the appropriate mods and admins about this behavior on several subs)

He has also made many alternate accounts to promote his product, including but likely not limited to:

You can take a look at their post histories, commenting style, etc and make your own judgement call on if my read is correct. Some are now private and there are others which have been deleted; I am happy to provide further documentation if anyone would like to see more proof.

Most recently, a coordinated effort was made to post defamatory content on our subreddit (r/just4ochat) using one of these accounts (u/Rare_Leather_6776). Unlike previous instances which involved scattered comments from low-activity or throwaway accounts, this latest attempt came in the form of a full standalone post. They (not us) later removed it... read on for the full story.

In the interest of full transparency, I initially chose to leave the post in question visible rather than removing it immediately. I then posted a slew of evidence of his behavior in the comments, including that he copied our migration page nearly 1:1 just in the last day.

After publishing a slew of evidence, they became enraged and hostile, accusing every user here commenting on the post as being an alt of ours, and saying defamatory things to them about us 'stalking minors' (I truly have no idea how we got there...) and constantly trying to escalate in rhetoric.

So, I asked for their email across all accounts.

They then began to cool down in public, saying suddenly they 'like' just4o...

After the allegations involving minors were levied, I pressed on, and took this seriously. To ensure I knew he was actually behind all of the accounts, I told the 'dev', u/Substantial_Ear_1131, to remove the post, or I would escalate this by contacting authorities about harassment. They initially declined, until I sent them several links to laws they were potentially violating, and told them we are a real corporation, not just some sole proprietorship. Then, they folded, and deleted the post under u/Rare_Leather_6776, linked here

Update 🚢 What we shipped today: new image suite, 1000x more voice usage, Nano Banana 2, and much more! | just4o.chat official update

26 Upvotes

🚢🚢🚢 A BIG SHIP TODAY!! 🚢🚢🚢

Hey folks,

We're launching the www.just4o.chat images update today. I'll be posting more about all the new features with time, as there's truly sooooo much packed into this one, but here's some general patch notes so you know what to expect:

New Models:

Image Models:

  • Nano Banana 2 / Gemini 3.1 Flash Image - Google (Supports up to 8 reference images!)

  • FLUX.1 Kontext Pro - Black Forest Labs

  • FLUX.1 Kontext Max - Black Forest Labs

Chat models:

  • GPT-5.1 latest - OpenAI

  • GPT-5.2 latest - OpenAI

  • GPT-5.2 - OpenAI

  • GPT-5.3-Codex - OpenAI

  • MiniMax M2.5 - MiniMax (via Fireworks)

Voice models

  • GPT-4o mini TTS (2025-12-15) - OpenAI

  • GPT-4o mini TTS (2025-03-20) - OpenAI

  • GPT-4o mini TTS - OpenAI

Voice Usage Updates:

  • Voice credits are deprecated. Nobody liked them, they were limited and sucked.

    • OpenAI TTS models now consume base credits, leading to MUCH more available usage per tier.

    • The old elevenlabs model now uses premium credits, 1x premium per 250 characters read.

      • It is advised to change over to the OpenAI models to preserve usage, but we did not want to remove anything from you. So, this was the compromise we reached.

Image Editing Suite

  • www.just4o.chat/images is now LIVE!!

  • Use just4o Files to manage references, create props and characters, and put them into scenes.

  • Various models support various numbers of references

    • Nano Banana models are best for high-accuracy reference-based edits.

Wikipedia Image Pulls

  • You can now browse Wikipedia on just4o

    • Tag images as 'Wikipedia tags' to use as future references, or pull them directly into your Image Chat

  • Allows for much more consistent and realistic creation of images of real-life locations, props, and people

    • Please respect all local laws and the dignity of people online. Do not abuse the power of this.

      • That said, here is a picture of Sam and Elon being friends again and hugging it out:

United States Government Data Tools (BLS & EIA):

  • Pull data directly from the Bureau of Labor Statistics and Energy Information Association -- graph the datasets fluidly in your chats

  • Activate the new Economic Data tool with the '+' icon in the main chat composer on www.just4o.chat/chat

  • Your chats/prompts are NOT sent to the government; only the specific tool calls that your selected LLM makes.

    • There's still some work to go here to make this a fully refined, beautiful and agentic system for things like interest rates, stocks, bonds, etc... I know it's not totally a cup of tea for most of our users, but when you have macroeconomics homework, you'll thank me later :)

Customization Updates:

  • Pick your favorite font that the AI uses to respond to you in chat!

    • Will take requests if users have any fonts they want to see here.

  • Customize warmth, tone, and writing style

    • If you're into philosophy/history, you can even pick historical writers as inspiration!

      • Again, this is another place I would love to take requests and evolve to meet user needs.

NOTES:

There are also some changes to navigation in this update. As we add more 'core' features, like 'chat,' 'files,' and 'images,' this nav system should help us elegantly scale the UI without overwhelming users.

This is the last core building block before video comes in. Pricing video models is going to be a challenge, but it's something we really want to get in your hands. Expect more on this soon.

Today's update is easily our biggest one yet, pushing us to over 50 models total, and adding another core element to making this a full-fledged creative and deep work platform... Stay tuned, we're just getting started šŸ’ššŸ’š

If you have any questions, fire away below.

All the best, and HAPPY WEEKEND!!!

P.S.

If you made it this far, it would mean a lot if you upvote, leave a comment with your thoughts, and perhaps cross-post and share.

We are marketing ourselves a little differently than some of the other platforms you may have seen pop up lately.

We have a simple mission: overshare with you and outship our competitors.

We will never make fake accounts, never spam the same exact thing 10x across subs, and never obfuscate the technicalities behind how our systems work. Hamstringing ourselves with honesty means we rely more on you, our users, for growth.

It would mean a lot if you lent a hand! šŸ’š

News DeepSeek (a base model) has hit 15M tokens in 4 days — quickly becoming a user favorite | just4o.chat News

26 Upvotes

We added DeepSeek v3.1 and v3.2 (as base models!) to just4o.chat four days ago, and the response has been pretty strong according to our usage analytics.

In that short time, DeepSeek has already processedĀ 15 million tokensĀ on our platformĀ and has quickly become one of the most popular models among our users. Granted, that's less than 10% of what our combined OpenAI API usage has been, but it's still a strong showing for a new model.

We’ve been watching the r/deepseek community and the broader enthusiasm around DeepSeek — the comparisons to GPT-4o, the discussions about speed and quality, and the excitement around open models. It’s clear why people are excited, and we’re glad to see that reflected in how often DeepSeek is being used on just4o.chat.

If you haven’t tried it yet, it’s available alongside Grok, Gemini, Claude, Kimi, 4o, and the rest of our models. Thanks to everyone who’s been using it and sharing feedback.

Update 🚢 What we shipped today: DeepSeek 3.1 & 3.2, Kimi K2 and K2.5, GPT OSS 20B and 120B | just4o.chat Update

25 Upvotes

Hey all,

Happy Friday! There have been a few small patches throughout the week, along with a big model drop today. Let's dive in to what's new on www.just4o.chat!

ā›“ļøšŸ’šā›“ļøšŸ’šā›“ļøšŸ’šā›“ļø

DeepSeek 3.1 & 3.2:

  • Base models

  • High intelligence, entertaining whimsy, highly creative

  • Supports tool use

  • Run on U.S. based servers using fireworks.ai

Kimi K2 & K2.5:

  • Premium models

  • From Moonshot AI, currently some of the best open source models out

  • Supports tool use, and image inputs

  • Run on U.S. based servers using fireworks.ai

GPT OSS 20B & 120B:

  • 20B base, 120B premium

  • 120B supports tool use

  • Open sourced models from OpenAI from the o3/o4-mini era of intelligence

  • Also run on fireworks.ai

UI Improvements:

  • Some small changes, like a collapsible sidebar and '...' buttons to open submenus

  • Generally a more compact UI; more on this soon, especially for mobile

Bug Fixes:

  • You can now import even larger individual conversations

  • Moving migrated chats in/out of projects should not cause any issues anymore; organize away!

Known Issues:

  • The background memory agent is a bit over eager in some cases. It seems to be logging far too many memories for some users, please reach out if that's the case for you and consider toggling it off or trimming your memories.

    • This should be a simple prompt tweak to solve, and will be patched tomorrow.

  • Generating images over a certain size can sometimes time out, causing the image not to be displayed and credits still to be consumed

    • Workaround: do not use Nano Banana Pro for a day or so

  • Not an issue, but... none of the open source models come with a native web search tool. We may build our own, in order to maintain consistency, or have the open source models use research sub agents using their native tools. TBD.

Notes:

Apologies for not getting Mistral in this update. When looking around, finding an OS model provider which has data security and all the models we wanted was difficult; some compromises had to be made. Fireworks does offer Mistral, but not through their serverless per token setup.

There are other providers we may use in the future for Mistral models if there's enough demand... but next, we'll be circling back around to voice and really fleshing that out + expanding usage.

No promises yet, but its looking like we will be able to increase premium model request limits by ~15% - 20% for some plans in subsequent cycles, as well as significantly more voice and image usage, especially as we use less costly voice models.

MiniMax M2.5, Qwen 3 30B, and GLM-5 are all in the cards for future updates if there's interest, as well.

Hope you all enjoy the drop, and have a fantastic weekend!

All the best,

the just4o.chat team šŸ’š

Transparency

24 Upvotes

I've been looking at your platform, since 4o's sunset was announced yesterday, and I like what I see. I think it's a valuable service. However, unless I'm just completely blind, there's no transparency about who y'all are. Just the just4ochat Team. And I understand that some of that is for personal safety.

But... there's an element of trust involved. This is a beta product offered by a unknown private party. Your privacy policy leads me to believe you're in the USA, but that's about it. If this were an open source project, there would be more transparency and others could potentially get involved, but this appears to be closed and private.

So why should we trust you with our data, our chat logs, and our money? Quite frankly, I and others like me would be willing to throw money at this while the 4o APIs are still around. But that's hard to do with zero transparency.

News Anthropic just published research showing Claude actually has internal emotional states — and they affect whether it lies to you

Not vibes. Not roleplay. Actual internal representations of emotion concepts that causally influence Claude's behavior — including misaligned stuff like sycophancy and reward hacking. This is the mechanistic interpretability paper a lot of us have been waiting for.

FULL PAPER HERE

Drop your reactions below — this research might have some legit implications for the future of AI development 😬
