🚀 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. 👉 https://github.com/huggingface/smolagents/releases/tag/v1.21.0
🚀 New in smolagents v1.20.0: Remote Python Execution via WebAssembly (Wasm)
We've just merged a major new capability into the smolagents framework: the CodeAgent can now execute Python code remotely in a secure, sandboxed WebAssembly environment!
🔧 Powered by Pyodide and Deno, this new WasmExecutor lets your agent-generated Python code run safely: without relying on Docker or local execution.
Why this matters: ✅ Isolated execution = no host access ✅ No need for Python on the user's machine ✅ Safer evaluation of arbitrary code ✅ Compatible with serverless / edge agent workloads ✅ Ideal for constrained or untrusted environments
This is just the beginning: a focused initial implementation with known limitations. A solid MVP designed for secure, sandboxed use cases. 💡
💡 We're inviting the open-source community to help evolve this executor: • Tackle more advanced Python features • Expand compatibility • Add test coverage • Shape the next-gen secure agent runtime
🚀 SmolAgents v1.19.0 is live! This release brings major improvements to agent flexibility, UI usability, streaming architecture, and developer experience: making it easier than ever to build smart, interactive AI agents. Here's what's new:
🔧 Agent Upgrades - Support for managed agents in ToolCallingAgent - Context manager support for cleaner agent lifecycle handling - Output formatting now uses XML tags for consistency
🖥️ UI Enhancements - GradioUI now supports reset_agent_memory: perfect for fresh starts in dev & demos.
🔄 Streaming Refactor - Streaming event aggregation moved off the Model class - ➡️ Better architecture & maintainability
📦 Output Tracking - CodeAgent outputs are now stored in ActionStep - ✅ More visibility and structure to agent decisions
🐛 Bug Fixes - Smarter planning logic - Cleaner Docker logs - Better prompt formatting for additional_args - Safer internal functions and final answer matching
📚 Docs Improvements - Added quickstart examples with tool usage - One-click Colab launch buttons - Expanded reference docs (AgentMemory, GradioUI docstrings) - Fixed broken links and migrated to .md format
