๐ 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!
๐ง 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: โ Isolated execution = no host access โ No need for Python on the user's machine โ Safer evaluation of arbitrary code โ Compatible with serverless / edge agent workloads โ 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. ๐ก
๐ก We're inviting the open-source community to help evolve this executor: โข Tackle more advanced Python features โข Expand compatibility โข Add test coverage โข 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 ๐ง โ๏ธ
๐ 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:
๐ง Agent Upgrades - Support for managed agents in ToolCallingAgent - Context manager support for cleaner agent lifecycle handling - Output formatting now uses XML tags for consistency
๐ฅ๏ธ UI Enhancements - GradioUI now supports reset_agent_memory: perfect for fresh starts in dev & demos.
๐ Streaming Refactor - Streaming event aggregation moved off the Model class - โก๏ธ Better architecture & maintainability
๐ฆ Output Tracking - CodeAgent outputs are now stored in ActionStep - โ More visibility and structure to agent decisions
๐ Bug Fixes - Smarter planning logic - Cleaner Docker logs - Better prompt formatting for additional_args - Safer internal functions and final answer matching
๐ 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: ๐ Bing support in WebSearchTool ๐ Custom functions & executor_kwargs in LocalPythonExecutor ๐ง Streaming GradioUI fixes ๐ Local web agents via api_base & api_key ๐ Better docs
