Task Categories
Pros
- +Open-source framework with a large community and extensive integrations
- +Modular architecture provides full control and transparency over AI workflows
- +Supports a wide range of LLMs, vector databases, and other tools, preventing vendor lock-in
- +Enables rapid development and deployment from prototype to enterprise scale
- +Offers advanced RAG capabilities including hybrid retrieval and self-correction loops
- +Provides enterprise support and a visual platform for enhanced development and scaling
Limitations
- -Requires Python knowledge and coding skills, not suitable for non-developers
- -Text-to-SQL approaches are still fragile and require human oversight for business-critical decisions
- -Dataset creation and evaluation for text-to-SQL is time-consuming and not fully automated
- -Ambiguity in natural language and database schemas can lead to incorrect SQL queries
