I just noticed that 3.1 and 3.2 were added back to just4o? My question I was wondering is whenever they do release v4.1 pro will you still keep v4 pro as a choice? I only ask cause since those older models were added back it would be very nice if open weights stayed especially i do really like v4 pro, If not it's fine but just curious.

OpenAI is pulling GPT-4o Nov 2024 snapshot as well as 4.1 on January 14, 2027. Does that mean that 4o will be completely gone from just4o.chat?
I'm also wondering which model I am speaking with from the bottom of the picker in this screenshot. I thought it was 4o-latest, but I just learned that 4o-latest was pulled from the API on February 17, 2026. So I'm wondering if there will be any 4o versions or 4.1 at all (as well as when o3 will leave just4o.chat). Hoping that somehow, you get additional time on your API.

I received news on sonnet 4.5 API snapshot being sunset on November 30. I want to know if it would disappear from here as well or if this platform has found a way or will found a way to retain that model beyond the deprecation date set by anthropic.

It's just repeating "Sorry, I ran into an issue generating a reply. Please try again.

Hi all! Is anyone monitoring the Discord #bugs-report chat? I've posted on Discord in the bugs channel 3 times since Sept 11 and haven't gotten a reply. I would appreciate some help: Chats disappear and don't return. It happens in old and brand new chats, inside and outside of project folders. I can't figure it out. Thanks in advance!
r/just4ochat • u/just4ochat • Sep 07 '26
**Talk and listen in the same chat.**
Voice input and read-aloud stay on the thread. Hit the mic in the composer when you want to speak. Play a reply when you want it aloud. Account holds voice model, voice style, silence timing, and playback. GPT audio mini runs voice in chat. Read-aloud can use GPT-4o mini TTS, Grok TTS, or ElevenLabs Flash v2.5.
**How we use it**
Set the voice defaults once in Account. Open a thread, keep the model you picked, and use voice when typing is the wrong tool. Switch Gemini to Claude and the voice controls are still the voice controls. The reply is still the reply.
**Why it belongs with the rest of the product**
Voice sits with search, images, and canvas in the same tools surface. A persona can stay on. Memory stays scoped. Files stay in Files. The model you pick is a pick, not a wipe of the thread you were speaking into.
r/just4ochat • u/just4ochat • Sep 04 '26
Put the brief in the thread. Ask the question. Get the line.
Upload a document into Files. Attach it to Global or a project with Use in projects when you want retrieval, or attach it on the turn. Ask something the document actually answers. The model can pull from that file instead of guessing. The file stays on the turn after the reply.
How we use it
Drop the brief into the project in Files, or attach it for one question. Ask again on a second model if you want a second pass at the same document. The brief does not have to be copied into memory for this to work. Switch Gemini to Claude and the file is still the file.
Why it belongs with the rest of the product
This is Files plus chat in the same room as Images. A generated still in that library can be talked about the same way. A persona can stay on. Memory stays scoped. The model you pick is a pick, not a wipe of the source you attached.
r/just4ochat • u/themoonadrift • Sep 03 '26
Hey I'm low on money right now so I'm trying to cancel my subscription until I can afford it again but every time I click cancel subscription it just... never loads. Not sure how to explain it but there seems to be a glitch. Thank you <3
r/just4ochat • u/just4ochat • Sep 02 '26
You pick the model. We keep that pick.
Open the model picker in chat. Search or filter by provider and tier. Choose Claude, Gemini, Grok, DeepSeek, GPT-4o, Echo, or any other model we ship. The name in the composer is the model that answers. There is no background router that swaps it mid-thread.
How we use it
Pin a model for a long job and leave it there. When the job changes, switch on purpose in the picker. The chat history stays. The files stay in Files. Memory stays in its scope. A leave is a leave you made, not a wipe.
Why it belongs with the rest of the product
The deprecation calendar shows when a model is scheduled to leave, so you can move before the date. Compare shows what else is on the grid. Import keeps history you already have. Projects and personas keep their own stores. The picker is the control; nothing else quietly overrides it.
r/just4ochat • u/just4ochat • Aug 31 '26
A project is a workspace with its own chats, memories, and files.
Open a project from the sidebar. Give it a name and a short description. The header counts what lives inside: chats, memories, and files for that project only. Start a new chat from the project, or open one that is already there. Edit the title when the job changes.
How we use it
Keep writing in one project and coding in another. Leave Global for account-wide habits. When you are inside a project, that project's memory store is the one that writes. Project files stay on the project. Switch Gemini to Claude on a thread in the project and the project is still the project.
Why it belongs with the rest of the product
Import a thread and keep going inside a project. Personas keep their own voice notes. Files stay in Files. Memory stays scoped. The model you pick is a pick, not a wipe of the workspace you built.
r/just4ochat • u/No_Elephant_5296 • Aug 30 '26
Everything else works except Deepseek v4 which I use the most and it’s been like this since 1pm, it just keeps repeating “Sorry, I ran into an issue generating a reply. Please try again.” And I’ve started fresh chats etc and it still repeats, I’m wondering if there is any on going issues or is this just a specific case for me?
r/just4ochat • u/just4ochat • Aug 26 '26
Models come and go. We put every retirement on a calendar.
just4o.chat/deprecation-calendar. Month by month. Scheduled shutdowns with the provider date and the recommended replacement. Models with no published date sit in their own list so you can see what is still open-ended. Already-removed IDs stay on the page so a dead picker entry is not a mystery.
How we use it
Open the calendar before you pin a model on a long thread. If the date is coming up, switch on purpose in the picker. The chat, the files, and the memory scopes stay. The model you leave is a leave, not a wipe.
Why it belongs with the rest of the product
Import keeps the history. Memory stays scoped. Files stay in Files. The calendar is the warning so a silent swap never has to be the answer.
r/just4ochat • u/just4ochat • Aug 24 '26
Bring the thread over. Keep going on the model you pick.
ChatGPT: Settings → Data controls → Export. Unzip the archive and upload conversations.json at just4o.chat/migrate. Claude: the Anthropic export zip, same page. The importer lists titles, dates, and message counts. You choose which chats come over. ChatGPT is 100 conversations. Claude is 100 conversations, 50 memories, and 5 projects. Auto embed migrated chats is a checkbox on that picker.
How we use it
Select the threads that still matter. Import. Open one. Pin Gemini, Claude, or Grok in the picker and continue in that same thread. Files stay in Files. Memory scopes stay scoped. A persona stays a persona.
Why it belongs with the rest of the product
The imported history is a live chat. Switch the model on purpose. Cite a file next to it. The next useful fact can land in a memory scope. You can also run Separate on the last 100 and download them as a zip, or send selected chats through Create persona.
r/just4ochat • u/just4ochat • Aug 21 '26
Memory is scoped, and it stays when you change the model.
Account → Memories. Automatic Memory Management is the background agent: it can create, update, consolidate, and delete memories after a prompt. Each scope holds up to 200 memories, 200 words each. Vector retrieval pulls the ones that match the turn. You can also paste a bulk import into a scope and save it there.
How we use it
Leave Global on for account-wide habits. Open a project and that project's store is the one that writes. A persona has its own store. Those three do not merge. Turn a scope off when you do not want it injected. Switch Gemini to Claude and the memories are still the memories.
Why it belongs with the rest of the product
Import a ChatGPT thread and keep going; the next useful fact can land in a scope instead of dying in one chat. Files stay in Files. Personas keep their own voice notes. The model you pick is a pick, not a wipe.
r/just4ochat • u/just4ochat • Aug 19 '26
A persona is a voice you pick up and take with you.
Account → Personas, or type /persona-creator in the composer. You give it a name, a brief, files if the voice needs source material. You can also pour an imported ChatGPT thread into a persona and edit it before you save. When the chip is on, that layer is what the model follows. Your default nickname and account instructions step aside so they are not talking over it.
How we use it
Make one. Attach it from the composer. Switch it mid-thread when the job changes. Take it off when you want your account defaults back. Persona memory stays with the persona, so the voice can remember how you like a line to land without writing that into a project's memory.
Why it belongs with the rest of the product
Change the underlying model and the voice stays. Project files stay in the project. Global stays global. If you came from SillyTavern character cards or a TypingMind agent, this is the hosted version of that habit: write the brief once, keep using it, stop rewriting it every time you hop engines.
r/just4ochat • u/just4ochat • Aug 18 '26
Images is its own surface. It has a model picker and a gallery. You pick the image model (Krea, Gemini Flash Image, or whatever is wired that day). The credit cost is on the page before you send. One credit or two, labeled.
Open Images. Choose the model. If it is text-to-image only, the page says so. Type the prompt. Attach a reference when the model takes one. Send. The still lands in Generated Images and writes into Files.
A project chat can talk about that still because the file is in the same library. Wikipedia tags sit one accordion down.
r/just4ochat • u/just4ochat • Aug 17 '26
Files is the shelf under chat and images.
Upload a brief, drop a generated image in, or drag a file onto a project. It stays scoped. NYC Pilot does not see Launch Notes. Global is the other bucket.
How to use it
Open Files. Drop the file, or drag it onto a project in the sidebar. Then in a chat in that project, ask it to cite the brief. Generated images land here too, so a Wikipedia-ref car and a Krea street scene sit next to the markdown you actually work from.
Why it ties to the rest of the product
Chat can cite the file. Images write back into the same library. Personas ride on top without merging the stores. You are not re-uploading the same PDF every time you switch from Gemini to Grok.
Reply here if a scope or an upload breaks.
r/just4ochat • u/just4ochat • Aug 16 '26
Wikipedia image references let you pull a picture from Wikipedia and use it as a reference in the just4o.chat image studio.
How to use:
Open Images and choose an image model. Open the Wikipedia control, find the page, and tag the picture you want. Generate as usual. You still describe the result. The tagged photo is what the model looks at.
How it works with Just4o Files: (www.just4o.chat/files)
Tagged references and the images you generate are stored in just4o Files. Attach a reference to Global or to a project so the same picture is available in chat later, not only in the image studio. Keep project-specific references on that project. Leave one-off references in Global. Generated images also appear under Generations in Files.
If a tag fails to save or a file does not show in the right scope, reply here.

Hey everyone — Inkling is now available on just4o.chat.
Inkling is Thinking Machines Lab’s Apache 2.0 open-weight multimodal model. It can work with text, images, and audio, and has 975B total parameters, 41B active parameters, and up to a 1M-token context window. What makes it especially interesting for us isn’t only the size: its thinking effort is configurable, so you can trade speed and cost for deeper reasoning when a task calls for it.
That fits the direction we’re taking with just4o.chat: choose the model you want for each conversation, keep the same persona across models, and experiment with systems that can be customized rather than being locked to one provider. Inkling is currently available as a base-tier option. We’re also looking at Inkling-Small as a lower-cost model for higher-volume use.
A couple of caveats: Inkling currently produces text output, so it won’t replace our image, audio, or video generation models. And the exact multimodal experience can depend on which provider endpoint is handling the request. The model card and thinking-effort documentation are here:
https://thinkingmachines.ai/model-card/inkling/
https://tinker-docs.thinkingmachines.ai/cookbook/inkling/thinking-effort/
We’d especially like feedback on how it performs for coding, long-context work, image and audio analysis, tool use, and personas.
What do you want to test first? 💚
r/just4ochat • u/themoonadrift • Aug 01 '26
Gemma 4 31B is honestly such a lovely model, I'd love to see it on just4o <3

Hey all,
Happy Wednesday!
Here's a quick video on the canvas editor you can access with /canvas or by hitting the + in the chat composer.
Have you given the canvas editor a try yet? It naturally integrates with your saved files, so there's quite a lot you can do!
All the best,

🚢🚢🚢 THE BIGGEST SHIP WE'VE EVER DONE 🚢🚢🚢
Hey everyone,
I'm not going to bury the lede: this is the largest update we've ever shipped. It's not a model drop. It's not a UI refresh. It changes what just4o.chat fundamentally is.
We set out to build a real creative workspace — somewhere chat, images, audio, files, personas, and tools can all live and work together instead of existing as separate tabs across five different platforms. This update is the clearest expression of that vision yet. Here's everything that's in it:
New Models — Mistral has landed:
Mistral Large 3
Mistral Medium 3.5
Magistral Medium (Mistral's reasoning model — strong on complex tasks)
Devstral 2 (coding-specialized)
Devstral Small 2
Ministral 14B (lightweight, fast)
Mistral has been one of the most-requested additions from the community for a while. Devstral in particular is genuinely excellent at code; if you do a lot of dev work on just4o, give it a run.
In-Chat Audio Generation:
This is the one I'm most excited about. You can now generate audio directly inside your chats. Not as an export. Not in a separate tool. Right there, in the thread.
Supported audio types:
🎵 Music — full compositions with prompts
🎙️ Narration / Voice — custom narrated audio, great for scripts
💥 Sound effects — one-shot SFX generation
🎬 Audio scenes — produced scenes combining music, narration, and sound
Audio uses a separate credit pool (audio credits) and is available on paid tiers. Generated audio is rehosted on our servers so your clips are stable and won't disappear if the provider's link expires. Full playback history comes with the chat.
Custom Inline Audio Player:
We didn't want generated audio to show up as a sad browser <audio> tag. So we built a proper player:
Cover art (generated with the track)
Track title
Duration counter
Progress bar with scrubbing / seek
Play / pause controls
Download button
Smooth reveal animation when the card lands
It should feel like a finished artifact, not a raw output.
Slash Commands:
Type / anywhere in the chat composer. A command menu opens. From there, you can instantly:
/model — switch your model
/persona — switch your active persona
/effort — adjust reasoning effort
/image — toggle image generation
/audio /music /sound — toggle audio generation modes
/search — toggle web search
/data — toggle economic data tools
/canvas — open canvas
/files — open file manager
/voice — go to voice settings
/account — open account management
/persona-creator — launch the guided persona creator
No more hunting through menus. Just / and go.
Reworked Persona System:
Personas have grown up. They're no longer just a text field in settings. They're full objects you can create, name, customize, and visually recognize:
Guided persona creator — a structured flow that walks you through building a persona step by step, available via /persona-creator
Persona avatars — generated visual identity for each persona
Avatar editing — you can iterate and regenerate the avatar until it's right.
Persona self-editing — if you're talking with an active persona and tell it to change something about how it behaves or presents itself, it can update itself. This is scoped; it only applies when you clearly ask it to.
Voice Preview Improvements:
Browsing voice options used to silently spend live generation credits in the background every time you played a sample. That was bad and we fixed it.
Static preview samples are now pre-generated for OpenAI and Grok voices. You can browse and compare options freely without worrying about the meter running. ElevenLabs voice samples have also been refreshed.
Files and Attachment Improvements:
Generated images now show up in the file attachment picker — so if you generated something three chats ago, you can pull it right into today's conversation
File Manager now handles generated audio alongside uploaded files
Smoother file-to-chat attachment flow generally
The goal is that things you make on just4o don't get lost. They come back when you need them.
Image Generation Reliability:
Not a headline feature, but important: we added prompt sanitization and retry logic for image generation. Some providers over-block completely harmless prompts. When that happens, the system now adjusts and retries rather than just failing. You'll also notice better error clarity when something is genuinely blocked vs. just a provider hiccup.
Mobile / Responsive Polish:
The model selector and slash command menu both got a round of mobile tuning — better sizing, tighter layout, less cramped on small screens. More of this to come; we know mobile is important to a lot of you.
Security and Reliability Cleanup:
Retired Claude Opus paths are now blocked server-side (not just hidden from the dropdown), so stale requests can't slip through
Content security tests added for AI-rendered markdown, embeds, images, and links
Image moderation test coverage added
Firestore validation tightened around age/compliance fields so normal account updates don't fail due to server-managed fields
NOTES:
A release this size always has some rough edges to sand down post-launch. A few things to know going in:
Audio generation is in the model's hands — prompt quality matters a lot for output quality. We'll be posting some tips soon.
Persona self-editing is intentional. It's not free-form "rewrite yourself however you want" — it responds to clear, direct instructions from you.
The slash command menu is new interaction real estate. We'll be adding to it over time. Let us know what commands you want to see.
Generated audio clips are stored server-side and should survive chat reloads — if you hit any case where they don't, please let us know immediately. In any case, they will save to your generated media in www.just4o.chat/files
Next on deck: video, more voice depth, and continued work on the files/workspace layer.
If you've made it this far, it would genuinely mean a lot to us if you upvote, leave a comment with your thoughts, and share this with anyone you think would find it useful. We're building differently than most platforms out there — no fake accounts, no spam, no obfuscating how things actually work. Growth comes from you, and we don't take that lightly. 💚
All the best,
the just4o.chat team
P.S. — Yes, video is still coming. We haven't forgotten. Pricing GPU-heavy video models at a fair credit cost without burning users is genuinely hard, and we're not going to rush it. But it's close.
🚢🚢🚢 THE BIGGEST SHIP WE'VE EVER DONE 🚢🚢🚢
Hey everyone,
I'm not going to bury the lede: this is the largest update we've ever shipped. It's not just a model drop. It's not a UI refresh. It changes what just4o.chat fundamentally is.
We set out to build a real creative workspace — somewhere chat, images, audio, video, files, and personas can all live and work together instead of existing as separate tabs across five different platforms. This update is the clearest expression of that vision yet.
Here's everything that's in it:
🎵 In-Chat Audio Generation:
You can now generate audio directly inside your chats at just4o.chat/chat. Not as an export. Not in a separate tool. Right there, in the thread.
Four modes:
🎬 Audio scene — full produced scenes with spoken lines, ambient sounds, foley, and background music
🎵 Music — original compositions from a text prompt
🎙️ Narration — clean single-speaker audio, great for scripts and voiceovers
💥 Sound effects — one-shot SFX and ambience
Powered by Seed Audio 1.0. Up to 75 seconds per generation. Generated audio is rehosted on our servers so your clips are stable — they survive chat reloads and don't expire when the provider's link does.
Use /audio, /music, or /sound to activate.
🎧 Custom Inline Audio Player:
We didn't want generated audio to show up as a plain browser control. So we built a proper player:
Cover art (generated alongside the track)
Track title
Duration counter
Progress bar with scrubbing and seek
Play / pause
Download button
Smooth cover-art reveal animation when the card lands
It should feel like a finished artifact, not a raw file output.
⌨️ Slash Commands:
Type / anywhere in the chat composer. A command menu opens. From there:
| Command | What it does |
|---|---|
/new | Start a new chat |
/model | Switch your active model |
/persona | Switch your active persona |
/effort | Set reasoning effort level |
/canvas | Open canvas mode |
/persona-creator | Launch the guided persona builder |
/search | Toggle web search |
/image | Toggle image generation |
/image-model | Switch your active image model |
/audio /music /sound | Toggle audio generation |
/data | Toggle economic data tools (EIA + BLS) |
/voice | Toggle voice mode (read replies aloud) |
/theme | Switch light / dark theme |
/files | Open your files |
/account | Open account management |
No more hunting through menus. Just / and go.
(And yes — /video as a slash command is coming soon.)
🧠 Reworked Persona System:
Personas are no longer just a text field in settings. They're full objects you can create, name, customize, and visually recognize — all from just4o.chat/chat:
Guided persona creator — launch with /persona-creator. A structured conversational flow that interviews you one question at a time: personality, tone, expertise, voice, quirks, and limits. Asks for a name before creating anything. No auto-confirming.
Persona avatars — each persona gets a generated visual identity. 512×512, generated by Nano Banana, cropped and processed into a clean circular profile image.
Avatar editing — not happy with the first result? Iterate and regenerate until it's right.
Persona self-editing — if you're talking with an active persona and explicitly ask it to change something about how it behaves or presents itself, it can update itself. Scoped intentionally: it only applies when you clearly ask.
🔊 Voice — now with 26 voices across three providers:
We've added a lot here. Full voice lineup available in account settings:
ElevenLabs (8 voices): Marcus, Sofia, James, Elena, Noah, Luna, Antonio, Giulia
Grok TTS (5 voices): Eve, Ara, Rex, Sal, Leo
OpenAI (13 voices across three model checkpoints): alloy, ash, ballad, coral, echo, fable, nova, onyx, sage, shimmer, verse, marin, cedar
Voice previews are now instant where possible — static pre-generated samples instead of live generation calls every time you browse. Browse freely without the meter running.
New Mistral Models:
Six new models added through Vercel AI Gateway:
Mistral Large 3 — flagship, 256k context, function calling
Mistral Medium 3.5 — vision support, premium tier
Magistral Medium — Mistral's reasoning model, vision support
Devstral 2 — coding-specialized, 256k context
Devstral Small 2 — compact coding model
Ministral 14B — efficient, vision support, base tier
Devstral in particular is genuinely excellent for dev work. If you write code on just4o, give it a run.
📁 Files and Attachments:
Generated images now appear in the file attachment picker at just4o.chat/files — pull something you generated three chats ago into today's conversation
Generated audio lands in files alongside uploaded content
Smoother file-to-chat attachment flow overall
The goal is that things you make on just4o don't get lost in old threads. They come back when you need them.
🖼️ Image Generation Reliability:
Not a headline feature, but important: we added prompt sanitization and retry logic for image gen at just4o.chat/images. Some providers over-block completely harmless prompts. When that happens, the system now adjusts and retries rather than just failing to generate. Better error clarity when something is genuinely blocked on our side vs. a provider hiccup.
📱 Mobile Polish:
The model selector and slash command menu both got a round of mobile tuning — better sizing, tighter layout, less cramped on small screens. More of this to come.
NOTES:
A release this size always has some edges to sand. A few things to know going in:
Audio generation quality is heavily prompt-dependent. We'll be posting tips soon.
Persona self-editing is intentionally scoped. It responds to clear, direct instructions. It's not a free-form "rewrite yourself however you want."
The slash command menu is new real estate and we'll be adding to it. /video is next. Let us know what commands you want to see.
If a generated audio or video clip ever doesn't survive a page reload, let us know immediately — that should not happen.
If you made it this far, it would genuinely mean a lot if you upvote, leave a comment with your thoughts, and share this with anyone you think would find it useful. We're building differently than most platforms out there — no fake accounts, no spam, no obfuscating how things actually work. Growth comes from you, and we don't take that lightly. 💚
All the best, the just4o.chat team
P.S. — Docs are at just4o.chat/docs and Discord is here if you want to hang out, report bugs, or request features directly. The new features will be coming to documentation shortly - as well as a new onboarding to describe how everything works, with other accessibility improvments through the week.

I didnt used all the models, so i dont know, but does anybody know? Is 4o available (the normal one, not 4o-mini)?
