5. Claude’s Files API lets you upload documents once and reuse them across sessions Perfect for datasets, analysis, and persistent file-based workflows.

🚨 BREAKING: Claude 4 just made every dev tool outdated. If you’re building agents, coding copilots or AI workflows - pause everything and read this. Anthropic dropped code-native super intelligence and it’s wild: 🧵👇

2. The best coding model in the world. Claude 4 model family now leads SWE-bench and even beats GPT-4. Replit says “Claude made precise changes across a massive codebase.” Cursor says “This is state-of-the-art for devs.”

3. Claude’s MCP connector lets you plug into remote tools like Zapier or Asana No client code needed. Just add a URL and go.

4. Claude 4 can now use tools like web search during reasoning. This opens up multi-agent, multi-tool workflows that actually scale.

6. Claude now supports 1-hour prompt caching Cutting costs by 90% and latency by 85% for long, multi-step agent workflows with persistent context.

7. Real memory. Not just tokens. Claude 4 can now save and reference memory files during tasks. Give it access to local files, and it becomes a context-aware assistant that remembers your codebase, logic, and style. The Pokémon demo isn’t a gimmick it’s proof of persistent understanding.

8. Code execution tool Claude can now run Python code via Anthropic API - enabling full data analysis, charting, modeling, and document automation in one flow.

9. Claude inside Github: Ask Claude to fix feedback directly within GitHub pull requests. Tag it in PRs, fix CI issues, or auto-respond to reviews.

10. Native support for VS Code, JetBrains, and GitHub. Edits show inline. Feedback happens in context. You don’t “prompt” it. You work with it.

11. Pricing Opus 4 = $15 per million tokens. Sonnet 4 = $3 per million tokens. Same price as before and far better performance. Startups, devtools, enterprise now can ship with agents.
