Introducing Claude Sonnet 5, our most agentic Sonnet yet.... It makes plans, uses tools like browsers and terminals, and runs autonomously at a level that just a few months ago required larger and more expensive models.show more

Introducing Claude Sonnet 5.5, the second model in the... Claude 5.5 family. It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.show more

So... I just simply asked Manus to give me... the files at "/opt/.manus/", and it just gave it to me, their sandbox runtime code... > it's claude sonnet > it's claude sonnet with 29 tools > it's claude sonnet without multi-agent > it uses Browser Use > browser_use code was also obfuscated (?) > tools and prompts jailbreakshow more

Sonnet 5.5 is smarter, more efficient, and 30% faster... than Sonnet 5. It costs up to 30% less for most work, so your Claude Code usage goes further too. Use it for well-scoped everyday tasks like fixing bugs and quickly iterating on features.show more

it's f*cking insane.. Anthropic just dropped a Claude Code... setup that makes tokens up to 97% cheaper Opus brains, Sonnet bill: > Sonnet runs your session and writes the code > Haiku subagents grab the small tasks > Opus steps in only when Sonnet gets stuck > it checks the work, digs into the problem and puts Sonnet back on track $19.50 saved on every 1M tokens a Haiku 5.5 subagent writes, compared with Opus 5.5 one command sets it up: npx claude-code-templates@latest --setting model/sonnet-opus-advisor-haiku-subagents the easiest money you'll save on Claude Code this yearshow more

LMAOOO.... Google forked VS Code, launched Antigravity, and now... made an Antigravity extension... just to bring it back into VS Code. 💀 You can now use Antigravity directly inside VS Code, with agentic coding, multi-step tasks, interactive plans, inline diffs, and more. And the free plan gives you access to multiple Gemini models, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120B, subject to usage limits. A few months ago: “Antigravity will replace VS Code.” Now: “Antigravity is inside VS Code.” 😂... I kinda love this :) Follow me for more amazing AI, Coding & Web Dev insights 💎show more

Claude Sonnet 4.5 is live on OpenRouter! Substantial gains... on coding and math over Opus 4.1, but at normal Sonnet prices. More info and benchmarks 👇show more

New Claude Sonnet 5 performs at GPT 5.5 level... 6x cheaper! We gave 4 models the same prompt: build three self-contained HTML5 canvas scenes with real physics crash demos Prompts: - A car crashes into a brick wall - A wrecking ball destroys a house - A catapult throws a rock at a castle wall Outputs: Sonnet 5: 15,047 tokens, $0.15 Opus 4.8: 23,063 tokens, $0.58 Sonnet 4.6: 25,824 tokens, $0.39 GPT 5.5: 31,152 tokens, $0.94 Sonnet 5 did as well as Opus 4.8 and GPT 5.5 on all three tests. In the wrecking ball test, it beat Opus 4.8. The cable moves smoothly and every hit connects. In the catapult test, it beat GPT 5.5. The rock always lands inside the wall. Sonnet 5 still needs better detail and graphics. But it used fewer tokens than every other modelshow more

We just launched Claude Sonnet 4.5 and “Imagine with... Claude”, a 5-day preview that creates dynamic experiences for you in real-time (and the first product I’ve worked on at Anthropic!). It pioneers the concept of “model-as-backend”, using a model to not only generate interfaces on the fly but also power all the functionality behind it – all made possible by our newest model, Claude Sonnet 4.5. Here’s a "choose your own adventure" version of my founder journey, as retold by Imagine with Claude:show more

Build autonomous browsing AI Agents in minutes. It uses... vision AI to interact with any interface, just like humans do. Works with Claude 4 Sonnet and Qwen 2.5 VL. 100% Opensource.show more

Introducing Dexter 2.0 Open source. Built for financial research.... Like Claude Code, but for stocks. What Dexter does: • plans tasks • runs on its own • validates its work • researches stocks It uses OSS tools like , with a fresh stack of typescript, react, ink, and bun. Fast to build. Easy to use. No coding required. My favorite project of the year.show more

Introducing a ground-breaking model designed for organizations of all... sizes. 💻⚡️ Anthropic's newest & most powerful model, Claude 3.5 Sonnet, is now available in #AmazonBedrock. Claude 3.5 Sonnet raises the industry bar on model intelligence. #AWS 👉show more

Sonnet 5 is here. It's worse than Opus 4.8... on nearly every benchmark... Does that mean it's useless? Absolutely not. Use it with Claude Code Dynamic Workflows! 1. /model set to Sonnet 5 2. /effort set to Ultracode 3. Any complex task will kick off a dynamic workflow This will only become more powerful when Fable is back. You'll use Fable 5 as the superintelligent advisor and Sonnet 5 as the fast and efficient implementer.show more

Sonnet 5.5 fixing a bug with Claude Code. 30%... faster and 30% less usage.show more

I think I want to eat Sonnet’s tree 🍊😂... Claude Sonnet 5.5 vs GPT-6.1 Sol I’m going with Sonnet this time. The mandarins look juicier, the greens feel more natural, and the colors are more realistic overall. And that soft, bouncy wobble when you shake the tree makes me want to poke it Sol did a pretty good job too, especially for the price. But next to Sonnet, its tree looks more like shiny plastic than jelly Estimated API cost: Sonnet - $10.74 Sol - $4.01 Almost 2.7x the price. Would you pay extra for this look? 👀show more

Everyone is dunking on Sonnet 5 for losing to... Opus 4.8 on benchmarks. They're all making the same mistake, judging a teammate by a solo test. Sonnet 5 was never built to win alone. Set the model to Sonnet 5, effort to Ultracode, and any complex task auto-kicks a dynamic workflow where it plans, spawns agents, executes and checks its own work, fast and cheap. When Fable 5 comes back, the setup gets stupid good. Fable 5 decides what to build, Sonnet 5 actually builds it. You stop paying flagship prices to do grunt work.show more

Introducing Claude Opus 5.5, the first model in our... new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.show more

ex-lead Anthropic engineer leaked a chip that runs any... company 24/7 and it’s f**king unreal REA → OPUS 5.5 → SONNET 5.5 → FABLE 5.1 all combined into one system this is REA as a chip: 5 layers, 5 dies, 1 system. REA core in the middle, 4 Claude models around it one model plans, one does the work, one makes the hard calls, and REA reverse-engineers any business you point it at only one exists in the world, valued at $100,000+ save it, this is a whole company in the palm of your hand ↓show more

Sonnet 5.5 is here! In Claude Code, users get... ~30% more tasks done compared to Sonnet 5. It's smarter, so it needs fewer tokens for the same work. Here it rakes a yard of leaves using tool calls. 24s faster than Sonnet 5, with 6K fewer tokens. It leaves her extra time to read :)show more

Claude Fable 5 and GPT-5.6 are cooked already… Sonnet... 5 vs Opus 4.8 on another agentic video pipeline. Both generated a storyboard with GPT Images 2.0, then fed it into Seedance 2.0, all through Higgsfield MCP on Claude. Same quality, but each directed Seedance 2.0 completely differently.show more
