ChatGPT Agent
- +Unifies browsing (Operator) and analysis (Deep Research) into one agent
- +Acts on a virtual computer: browses, runs code, and builds deliverables
- +Available across ChatGPT paid plans with no separate product to adopt
- -Agentic browsing can be slow and error-prone on complex sites and login/CAPTCHA flows
- -Requires user oversight; not a hands-off autonomous worker
smolagents
- +Tiny, transparent core (~1,000 lines) that is easy to read and extend
- +Code-as-action approach enables natural composability
- +Model-agnostic, multimodal, with sandboxed execution and Hub sharing
- -Minimalist by design: fewer batteries-included features than larger frameworks
- -A framework, not a product: you build, host, and secure agents yourself
