- + Define custom plugins and functions for AI agents to call
- + Built-in memory and context management for multi-turn interactions
- + Strong Microsoft ecosystem integration (Azure, Copilot)
- + Active open-source development with regular updates
Cons
- - Steeper learning curve compared to simpler LLM libraries
- - C# support more mature than Python implementation
- - Requires managing your own LLM API keys and costs
E2B
Pros
- + Execute untrusted agent code in isolated environments
- + Spin up sandboxes in milliseconds with minimal overhead
- + Integrate via simple SDK calls for Python and JavaScript
- + Persist files and state across multiple agent sessions
Cons
- - Requires cloud connectivity; no local-only option
- - Pricing based on compute usage can scale with high-frequency agent runs
