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.

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 jailbreak

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 model

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:

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.

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.

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.

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.

Now it all makes sense, Claude Sonnet 4.5 can keep its coding focus for nonstop 30 hours. And Dario Amodei just said few days back that, "The vast majority of code that is used to support Claude and to design the next Claude is now written by Claude. It's just the vast majority of it within Anthropic. And other fast moving companies, the same is true." The shift has started in all tech companies. --- From 'Axios' YT Channel.

I built a tool that runs autoresearch 24/7 in the cloud. It can scale to thousands+ of parallel experiments. Uses Modal (for GPUs) and Cloudflare Workers. Wraps coding tools Codex/Claude. Here's a quick demo ▶

Ain't no fuckin way... you can now use Antigravity inside VS Code. 🤯 Google has launched its official Antigravity extension for VS Code. So instead of switching to another editor, you can now bring Antigravity's AI coding experience into VS Code. And the crazy part? The free plan gives you access to models like Gemini, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120B, with usage limits. Kinda wild how a few months ago people were saying VS Code was getting replaced by Antigravity... and now they're basically sitting together. 😂 Honestly, I like both :) Follow me for more amazing AI, Coding & Web Dev insights 💎

Someone just broke the paywall on Claude Design… and almost no one noticed. It’s called Open Design. No subscription. No limits. No “Pro plan required.” Just raw access. 👉 Turn prompts into real UI/UX 👉 Generate designs with Claude 👉 Replace expensive design tools 👉 Fully customizable (open source) This isn’t a tool. It’s a shortcut around the entire design economy. Most people will ignore this. A few will build insane things with it. Guess which side wins. Save this before it explodes Repo:

Most people are still asking: Opus or Sonnet? That may already be the wrong question. Claude is starting to look less like an AI model and more like an AI operating layer. The models are only one part of it. Around them, Anthropic is building the pieces required to move AI from a chat window into real software: → Reasoning models → MCP and tool connectivity → Agent frameworks and SDKs → APIs and managed agents → Memory and context systems → Security and permissions → Evaluation pipelines → Governance and observability → Production deployment infrastructure And that changes what it means to be good at AI engineering. Prompting is becoming table stakes. The harder skill is understanding how an agent gets context, remembers what matters, accesses tools safely, evaluates its own output, survives failures, and operates reliably inside a production system. That is a very different skillset from simply knowing which model tops a benchmark. In 2026, the advantage may not belong to the person who knows the best model. It may belong to the person who understands how the entire AI stack fits together. Claude’s evolution is a good preview of where AI engineering itself is heading.

Claude Code's effort parameter is something you need to keep in mind before starting any task It's not just about picking the right model anymore (Haiku, Sonnet, Opus). Now you also need to think about which effort level to use before each task. One tip I always go back to: when Opus can't solve a problem, just adding ultrathink makes things click, it's almost magic. We wrote a post at Hedgineer benchmarking each effort level by cost and time Read it here:
