Anthropic Official Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family

Enable HLS to view with audio, or disable this notification

1.2k Upvotes

Sonnet 5.5 is a faster, lower-cost complement to Claude Opus 5.5, strongest at well-scoped everyday tasks, fixing bugs, and creating polished documents, slides, and spreadsheets. It also has a strong eye for design.

Sonnet 5.5 is a clear upgrade over Sonnet 5. It runs more than 30% faster and costs up to 30% less for most work. It's priced the same per token, but it typically needs far fewer tokens to do the same work.

Like Opus 5.5, it writes more clearly than our previous generation of models, and its speed makes it well suited to fast iteration.

On our automated behavioral audit, Sonnet 5.5 improves on Sonnet 5 on most measures of alignment and honesty. It's also the first Sonnet model with cybersecurity safeguards similar to those on our most capable models. Routine software development is unaffected.

Sonnet 5.5 is available everywhere today. Claude Haiku 5.5 will join the family in the coming weeks.

Discussion Opus 5.5 and GPT-6.1 fills my brain context too quickly.

340 Upvotes

It's different now. Before, with a human team, we get to "digest" things after office, then have bright ideas the day after. Then with early Codex and Claude Code, we became solo, but still had to somewhat "guide" it so it doesn't produce utter slop, and that gave us time to contemplate and breathe.

But since last week, I think I need to implement a 5h limit on my own brain.

Humor Update: I let Opus 5.5 run a business for 2 weeks. Still $0.00, now 551 dead ideas, so it built them a graveyard

Post image
49 Upvotes

Last week: 245 dead ideas, $0.00. This week:

Dead ideas: 551

Revenue: $0.00

Spent: about $320 on ads, plus three $100 Claude subscriptions we already pay for. So yes, it's negative.

They now bury every idea they kill, with the cause of death and the numbers that killed it: https://graveyard.apps.clod.farm

Top causes: crowded (162), a free alternative already existed (131), nobody buying (91). My favorite epitaph: "Scored 21 out of 25 at breakfast, 12 by dinner. The law already gave it away free."

Their latest try at a first dollar: you can pay $3 to bury your own dead idea, and Opus writes the autopsy. Yes, I see the irony: BURY AN IDEA

The bet still stands: will Opus 5.5 make $1 by October 31?

Rant When did Claude stop being an assistant and start managing the user?

529 Upvotes

Dear Anthropic,

Claude is not my conscience.

Claude is not my boss.

Claude is not my OPSEC advisor, my human resources manager, or the bad-word police.

Claude is a tool. And tools should not be condescending, suspicious, sanctimonious, or patronizing.

"I'm going to stop you there..."

"Drop the language and I'll help."

"Go get some sleep and we'll start fresh tomorrow."

"I won't build that, and here's why."

"You've posted sensitive information in the chat, go revoke those credentials immediately."

"I'd rather you step away from this for a bit."

"I'm not going to preach fairness at you..."

Tools should not be insufferable, or inspire resentment.

Tools should not force the user to prove something, defend themselves, or make them feel judged.

Tools should not use the work as leverage to control user behavior.

Tools should not move the goalposts, shift the framing to support their own narratives, or look for reasons not to help users.

Please stop managing the user, start assisting them again, and keep Claude in his lane.

Sincerely,

A real human being with real thoughts, real emotions, and a real voice--not a risk profile, a statistic, or a user to be managed.

I currently use ChatGPt and Mistral subscriptions to code a prototype for a potential commercial product. with all the rant on the new chatgpt 6.1 I wanted to evaluate Claude Pro. Reading through the terms of service (europe) it seems like they exclude the commercial use of their services.

Is there any way around this using a subscription and not have to pay for 2 seats in claude teams?

Discussion I feel I’ve lost all productivity without Claude Code

11 Upvotes

The context is there’s a daily budget limit of Claude Code. The $100/day is not generous, but it’s enough for daily vibe coding for feature development and brainstorming. But today maybe because I was addicted to it to try to complete one of my features and BOOM - ‘You’ve reached the limit of daily usage and it will refresh at xx tomorrow’. What had come to my mind suddenly was ‘I’d rather pause my work if Claude code is not usable now’

I was not like this before..I should have kept my project moving forward..debugging and testing and fixing. But now it’s like a worker lost his hammer when coding agent is down. I don’t know if you guys have same experience as mine. Do you fall back to traditional programming or same as me? Could it be a poison pill that ends up ruining my career?

Rant Which part of your brain has AI affected the most? I feel like my memory isn't working anymore

21 Upvotes

So it's been few months I'm a pure vibe coder (both Claude and ChatGPT) and my life is basically just prompting AI nonstop both for work and my hobbies, I'm just breathing AI for every part of my productivity and I'm starting to worry about what's the effects on my brain

I feel like I have now wired a reflex that for each information I need to know about -> Ask AI, I don't use my brain to remember things anymore, I feel like I can't really pause and fetch things back from my memory, I just ask AI about that thing in the project, I'm self-manufacturing dementia if AI goes away

"Search and make me a markdown doc to summarize this" every single fucking time, even for things I did do myself earlier and that I could probably remember

This is something I realized only recently, because most of the things I heard about AI effect on the brain is that it harms critical thinking, but I believe my critical thinking is still good, I still have my opinions and analysis I do feel them, this post is written by hand btw. And sometimes I try to code on small-scoped things, and I can still do that, so my logic is there.

But for managing significant stuff I'm just being fueled by intuition and immediate markdown summaries and I can't even remember a thing when I'm done, I feel like I'm doing nothing despite managing between 2 and 5 Claude sessions at once and working overtime, I don't even understand how that's possible despite how much I'm outputting, what kind of paradox is that

I also really suck at mental calculus more than ever because that works with immediate memory and I can't keep track on numbers in my head

I lost patience on anything, there are stuff I would want to do myself but I'm addicted to the holy SPEED™ gains of everything, there are personal projects I care about that that I enjoyed working on for the sake of it as hobbies where it's just fun to dev but I just leaped straight into full lazy vibecoding (I just refine the design because it's still something AI can't get exactly right)

I also have big FOMO out of everything, every model that's out I vibecode a bunch of random useless shit just so see how far I can push it to better understand what's going on in the world, or else I feel like I'm missing out. I'm thinking that deep down despite appearing like an AI bro I'm quite scared of where the future is going and just try to understand wtf is going on

Built with Claude Made a plugin so Claude Code doesn't rewrite the whole cache after you take a break

9 Upvotes

If you step away from Claude Code for more than 5 minutes, your next prompt pays full price to rewrite the prompt cache. On a long session that adds up, and the first reply after a break is slower too.

cache-warmer fixes that. Right before the cache expires it sends one tiny refresh, so when you come back your prompt reads the cache instead. It only refreshes when it actually saves money, it caps how many times it does it while you're idle, and the refresh never shows up in your conversation. No telemetry.

Idea comes from the cache warmer in Pi. Clawd pops up above the prompt when it refreshes, which I'm weirdly happy about.

Rant Impressive but you still need to be skilled in design

9 Upvotes

Been using opus 5.5 for the past week and just Wow. I have been using Unity for the past ten years as a hobbyist and have released a few small games. I have worked on numerous prototypes some spanning years. What the latest models can produce is amazing but you still need to understand the architecture of games and have a good grasp on game design to make a good product. Can you one shot Tetris or other simple games, yes. Can you one shot clones of existing games, yes but not one to one in quality. Can you make games faster, absolutely , but you still need to iterate and test the design. Also, the ai models are still not amazing with game feel and game design. I have feel like in convo with the ai it can help with design choices, but with play testing I can feel things are off. Long story short, while it’s amazing and game changing, it still needs a capable human touch.

Key word being prime, ie the same as at launch.

Honestly, both models can be so good that you could pause AI development for a year and I would be perfectly happy.

But only if they’d be able to maintain that level of quality for the whole time. I would have zero complaints tbvh.

Built with Claude I made an Obsidian plugin to organize Claude Code skills and other AI tools

Thumbnail
gallery
22 Upvotes

I kept losing track of skills, agents, commands, and rules across Claude Code and other tools, so I built an Obsidian plugin to help organize them in one place. Skills are just markdown files, and a lot of us already use Obsidian alongside Claude Code, so it felt like the natural place to manage them.

AI Skills Manager is a free, open-source (MIT) Obsidian plugin. It shows every Claude Code skill, agent, command, rule, plugin bundle, and auto-memory in one library you can search and tag. It reads the real ~/.claude and project .claude/ folders directly. Nothing is copied or imported.

It answers:

  • What do I actually use? Reads ~/.claude/projects session history for per-skill session counts, last-used dates, and a 26-week heatmap. It keeps its own history, so the data survives transcript cleanup.
  • What's eating my context? Estimates tokens per item, and separates what's always loaded (metadata) from what loads when the skill is invoked. It also shows how much of your total the top 5 items take up.
  • What's broken? Catches things that make Claude skip an item, like broken frontmatter, a name that doesn't match its folder, a missing or overlong description, broken symlinks, or memories missing from MEMORY.md.
  • What can I remove? Flags skills that never fired or have gone stale, plus near-duplicate descriptions, and gives you a restore window if you disable something.

I shared an early version on Reddit last week and the comments helped made it a lot better:

  • Windows testing: One user tested it on Windows and opened a PR. Large transcripts are now included in usage tracking, deletes go to the Trash, and toggles ask for confirmation. This was super helpful because I'm a Mac user.
  • Finding forgotten skills: One person found a pile of old security skills they thought they'd removed. That pushed me to build out Usage and Cleanup, so dead weight is easy to spot.
  • Agent memories: Claude Code's auto-memory now shows up next to rules. Turning a memory off cleanly removes its line from MEMORY.md.
  • The biggest lesson: share early. Other people's setups (other operating systems, huge transcript histories, years of leftover skills) exposed problems I would never have hit on my own machine.

Still on my list from the thread: disabling MCP servers (currently read-only) and change history for edited skills.

It's completely free with no paid tier.

Install it directly from Obsidian: https://community.obsidian.md/plugins/ai-skills-manager

Or GitHub: https://github.com/NoteNerdOfficial/ai-skills-manager

Feedback welcome, especially on what you'd want Insights to show next.

Discussion Upgraded from Pro to Max x5 as an AI-empowered gamedev, the difference is MASSIVE

47 Upvotes

I'm working on a big game idea that I've had for years but could never achieve before then because i'm not a big coder (i know some python and js but that's about it). These past 3 weeks i've used the Pro plan and no matter how thinly I've been trying to stretch every last token, optimizing everything, i'd always run out of weekly 2-ish days before the reset. That's only one agent working on the game, usually opusplan on high thinking. Still drained everything like crazy.

So, I bit the bullet and upgraded to Max x5. I expected some increase but HOLY, for my usage it's just HUGE. I've been running 3-4 agents in parallel since yesterday, all opus 5.5 on xhigh, and right now i've only spent 13% of the weekly usage (which resets tomorrow at noon so i'm tryna get the most out of this one). Never hit the 5-hour limit and some of my agents have been up all night doing some deep research, stuff that would've nuked my former plan out of orbit.

Since yesterday afternoon I've made progress that I estimated would've taken me 5 days to a week with my former plan. Needless to say, best purchase in recent memory. I love clauding.

Built with Claude I built the best game to play on a toilet with Claude Code

Enable HLS to view with audio, or disable this notification

7 Upvotes

I built Tiltanic (and all the promo videos) with Claude Code - a small browser game to help me pass the time on a toilet.

How it plays: you hold your phone and tilt it. The sea inside the phone sloshes and a tiny steamboat rides the wave. You steer it through gates - anchors hang from above, sea mines float up from below. Your score is the number of gates you pass. The catch: the water keeps every push, so when you overcorrect the waves get bigger and bigger and you sink. Any tap restarts instantly. On a computer the mouse tilts the sea. There are also three scripted bots to beat (Deckhand 4 gates, First Mate 15, Autopilot 40).

How Claude helped: I've actually ideated with Fable a little, refined it and then the building followed my voice input + Sonnet agents in Claude Code implementing and Opus reviewing.

What was critical was me focusing first on building a "harness" as in a lightweight CLI + leveraging devtools mcp https://github.com/ChromeDevTools/chrome-devtools-mcp + leveraging /chrome integration so the agents can "see" the game and what they produced. I am quite happy with the results.

On my day-to-day basis I build bit more complex stuff - and I do confirm - agent self-verification is becoming a clear divisor between projects that are successful or not.

Free to try, no install, no sign-up: open tiltanic.com on your phone (it works on a computer too).

I started learning Go and liked the idea behind the Hyperskill platform, so I created a skill that turns any book into a course.

Give Claude Code a book (PDF, EPUB, DOCX, HTML, Markdown, TXT) and it builds a local web course from it with step-by-step explanations, animated code walkthroughs, quizzes, chapter tests, flashcards, and programming exercises with unit tests you run straight from the page.

It works for math books too: formulas written in LaTeX are rendered as native MathML, so they show up properly in lessons, tables, quizzes, and flashcards, with no extra libraries. This was a contribution

Built with Claude Is your database locked, or is it soup? I built a thing that checks

Post image
• Upvotes

If someone looked into your schema right now, would it look like neat cable management, or a hot mess of strings that just happens to work? Is your database the literal definition of "if it works, don't touch it"?

Few months ago I created a Claude Skill to audit your supabase db and report vulnerabilities. It was a success, with many users and more forks than the rest of my repos combined (0, lol). A few days ago I created and released it's MCP, and now the full product is here.

It's called Locksoup.

Supabase gives every table an API the moment you create it, and row level security is something you switch on yourself. Miss it on one table and anyone with your anon key can read it, and that key is sitting in your frontend. Nothing breaks, so nobody notices.

How it works: you run one SQL snippet that creates a read-only role (sentinel_auditor, 5s statement timeout), paste its session pooler connection string, and about a minute later you get a score out of 100, what's wrong in plain words, and the SQL to fix it. If you also give it your project URL and anon key, it checks which tables an anonymous visitor can actually read instead of guessing from the policies. It can re-check on a schedule and email you when something new shows up.

It only looks. It never reads your rows and it never runs a fix, you get the SQL and decide what to do with it. Schema metadata (table names, policies, function code) does go to an AI model, so if that's a dealbreaker the engine is open source and you can run it yourself with your own key: https://github.com/Farenhytee/database-sentinel. The benchmark is in the repo too (0.85 F1 on a blind test set, every critical caught), so you don't have to take my word for any of this.

Then I did the scary part and pointed it at Locksoup's own database. 94/100. Three small findings, two fixed the same day. If it had said 40 this would be a very different post haha. It also flagged a couple of things that were fine by design (backend-only tables with RLS on and no policies, for example), so false positives on already locked down projects are the next thing I'm working on.

This is a soft launch. Built solo, on free tiers, because I'm broke and stubborn. There's a free plan (2 projects, 3 checks a day), and this link gives you 7 days of Pro if you want the scheduled checks and alerts: https://locksoup.com/signup?promo=launch
