π smolagents v1.21.0 is here! Now with improved safety in the local Python executor: dunder calls are blocked! β οΈ Still, not fully isolated: for untrusted code, use a remote executor instead: Docker, E2B, Wasm. β¨ Many bug fixes: more reliable code. π https://github.com/huggingface/smolagents/releases/tag/v1.21.0
π 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!
π§ 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: β Isolated execution = no host access β No need for Python on the user's machine β Safer evaluation of arbitrary code β Compatible with serverless / edge agent workloads β 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. π‘
π‘ We're inviting the open-source community to help evolve this executor: β’ Tackle more advanced Python features β’ Expand compatibility β’ Add test coverage β’ Shape the next-gen secure agent runtime
Let's reimagine what agent-driven Python execution can look like: remote-first, wasm-secure, and community-built.
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 π§ βοΈ
π 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:
π§ Agent Upgrades - Support for managed agents in ToolCallingAgent - Context manager support for cleaner agent lifecycle handling - Output formatting now uses XML tags for consistency
π₯οΈ UI Enhancements - GradioUI now supports reset_agent_memory: perfect for fresh starts in dev & demos.
π Streaming Refactor - Streaming event aggregation moved off the Model class - β‘οΈ Better architecture & maintainability
π¦ Output Tracking - CodeAgent outputs are now stored in ActionStep - β More visibility and structure to agent decisions
π Bug Fixes - Smarter planning logic - Cleaner Docker logs - Better prompt formatting for additional_args - Safer internal functions and final answer matching
π 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
New in smolagents v1.16.0: π Bing support in WebSearchTool π Custom functions & executor_kwargs in LocalPythonExecutor π§ Streaming GradioUI fixes π Local web agents via api_base & api_key π Better docs
smolagents v1.14.0 is out! π π MCPClient: A sleek new client for connecting to remote MCP servers, making integrations more flexible and scalable. πͺ¨ Amazon Bedrock: Native support for Bedrock-hosted models. SmolAgents is now more powerful, flexible, and enterprise-ready. πΌ
