Latest smolagents release supports GPT-5: build agents that think, plan, and act.
⚡ Upgrade now and put GPT-5 to work!
🚀 smolagents v1.21.0 is here!
Now with improved safety in the local Python executor: dunder calls are blocked!
⚠️ Still, not fully isolated: for untrusted code, use a remote executor instead: Docker, E2B, Wasm.
✨ Many bug fixes: more reliable code.

🔥 This feature is live in smolagents v1.20.0!
Try it out.
Break things. Extend it. Give us feedback.
Let's build safer, smarter agents; together 🧠⚙️

Let's reimagine what agent-driven code execution can look like: remote, safe, and Wasm-powered.
👷 Want to help?
This is a foundation we're inviting the community to build on:
• Add feature support
• Expand compatibility to new use cases
• Help make agents even more secure + capable
Contribute, test, break things, and PR back 🚀
🙅♂️ Why no network calls (for now)?
Because Pyodide in Node.js needs experimental flags for stack switching, and some APIs (like urllib3) aren’t yet compatible out of the box.
But this is just the beginning.
🚧 What’s supported right now?
✅ Basic Python logic
✅ Standard control flow
✅ Limited stdlib support
❌ No HTTP requests (yet)
❌ No advanced I/O or external packages
It's early: a solid MVP for secure use cases. 💡
🔐 Why WebAssembly?
WebAssembly = portable, fast, and secure.
It enables:
• Safe remote execution of Python code
• Zero access to the host machine
• Consistent, deterministic environments
• Serverless + edge-compatible agent workflows
💥 Big milestone just dropped in smolagents:
The CodeAgent can now execute Python code remotely in WebAssembly, powered by Pyodide + Deno!
Your agent-generated Python runs in a secure, sandboxed Wasm runtime: no local execution required.
Here's why this changes the game 🧵👇

What security measures do you take when running AI-generated code? Let’s discuss! 👇
#AI #smolagents #Python #Security
6️⃣ Upgrade Now & Stay Safe! 🚀
Check out the latest smolagents release and start building safer AI agents today.
5️⃣ The Best Practice: Use Sandboxed Execution 🔐
For production-grade AI agents, we strongly recommend running code in a Docker or E2B sandbox to ensure complete isolation.
4️⃣ Security Disclaimer ⚠️
🚨 Despite these improvements, local Python execution is NEVER 100% safe. 🚨
If you need true isolation, use a remote sandboxed executor like Docker or E2B.
