Cons
- -Requires paid OpenAI API key for optimal performance and to avoid rate limits
- -Limited to 25MB file upload size in the hosted version, which may restrict use with larger documents
- -Currently supports limited document formats, though expansion is planned on the roadmap
- -Some examples use potentially unsafe tools like PythonAstREPLTool that are vulnerable to arbitrary code execution
- -Limited to the LangChain ecosystem and may not showcase integration with other agent frameworks or libraries
- -Most examples require external API keys and services to run fully, creating setup barriers for immediate testing
