🏷️ Labels: Fastapi, Chroma, LLM, Backend Development, Prompt Engineering
📂 Project: Dev
Session Goal
The session aimed to design and implement FastAPI endpoints for Chroma integration, review existing RAG pipeline scripts, and develop a prompt builder utility for LLMs.
Key Activities
- Designed FastAPI endpoints to interact with Chroma and LLMs, focusing on architecture responsibilities and error handling.
- Reviewed a Streamlit/Haystack script to identify integration opportunities with FastAPI and Chroma.
- Developed a Python utility for building prompts for LLMs, including provenance tracking and text truncation.
- Implemented a prompt builder module using Jinja2 templates for summarization tasks.
- Documented backend and frontend status, providing actionable fixes and CLI commands.
- Outlined code patches for TEI parser and Chroma client integration.
- Reviewed Chroma integration, providing recommendations for improvement.
- Implemented a canonical embedding adapter module for consistent embedding operations.
Achievements
- Completed the design of FastAPI endpoints and reviewed integration scripts.
- Developed a functional prompt builder utility and module for LLMs.
- Documented system status and proposed code patches for backend improvements.
Pending Tasks
- Integrate the prompt builder module into background jobs.
- Implement recommended improvements for Chroma integration.
- Further enhance the embedding adapter module based on initial recommendations.
