Transformers Agents 2.0 released; transformers.agents now a standalone smolagents library

AI Impact Summary

Transformers Agents 2.0 introduces two new agent types and shifts the ecosystem to a standalone smolagents library, emphasizing modularity, transparency, and community sharing. The release touts an Llama-3-70B-Instruct agent outperforming GPT-4-based agents on the GAIA Leaderboard, signaling a potential cost-performance advantage for agent-based workflows. The upgrade decouples the agent framework from the core transformers package, requiring teams to adjust imports and pipelines to smolagents while preserving API familiarity. Expect changes to tooling and patterns around Tool/Toolbox/CodeAgent/ReactAgent, which will influence development, monitoring, and onboarding of new agents.
