Claude Skills are awesome, maybe a bigger deal than MCP https://t.co/1wIYcTFrzI

Anthropic this morning introduced Claude Skills, a new pattern for making new abilities available to their models: Claude can now use Skills to improve how it performs specific tasks. Skills …

Let me pitch you Skills: - They allow anyone to customize agents with a simple primitive — files - They give us continuous learning until continuous learning arrives - They are powerful, composable, and sufficiently AGI-pilled - you can now say “probably a skill issue” at work

Multi-agent search was easy to prototype (V1 only took me a day) but incredibly complex to bring to production. Feels like building RAG in 2022: we see the promise but are still figuring out the primitives. Sharing our journey so far - hope it helps your exploration!
New on the Anthropic Engineering blog: how we built Claude’s research capabilities using multiple agents working in parallel. We share what worked, what didn't, and the engineering challenges along the way. https://t.co/k3Gzd4HkLg

My workflow for the past few months: - Write a design doc (with Claude ofc) - Ask Claude to generate tests - Verify the tests - Let it cook
This approach has made Sonnet the model of choice for developers worldwide. In addition to our new model, we're launching Claude Code, our first coding tool, in a limited research preview. With Claude Code, you can delegate substantial tasks to Claude—right from your terminal.

Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.

Success in the LLM space isn't about building the most sophisticated system. It's about building the right system for your needs. Had a lot of fun writing this with @ErikSchluntz!
2025 will be the year of agentic systems The pieces are falling into place: computer use, MCP, improved tool use. It's time to start thinking about building these systems. At Anthropic, we're seeing a few best practices emerge - we wrote a blog post with our findings:

Introducing an upgraded Claude 3.5 Sonnet, and a new model, Claude 3.5 Haiku. We’re also introducing a new capability in beta: computer use. Developers can now direct Claude to use computers the way people do—by looking at a screen, moving a cursor, clicking, and typing text.

How much data do you need to fine-tune GPT-3.5? @barry_zyj et al. have a great article showing that you only need ~100 datapoints for better output structuring and customizing the tone. Lots of great stuff incl. cost/latency analysis. Check it out! https://t.co/nKU2ebHKSE
