Running both lets us measure latency, reliability, governance, and developer ergonomics—without changing our UI or schemas.https://site.fredlab.dev/blog/rico-learns-to-reflect-smarter-document-qa-with-self-rag-techniques/Tue, 05 Aug 2025 17:00:00 +0200https://site.fredlab.dev/blog/rico-learns-to-reflect-smarter-document-qa-with-self-rag-techniques/Rico, the document expert agent in Fred, now leverages Self-RAG-inspired strategies to assess document quality, retry with smarter queries, and generate more accurate answers. This post explains the improvements.https://site.fredlab.dev/blog/from-csv-to-agent-tabular-data-gets-smart-in-fred/Fri, 11 Jul 2025 14:00:00 +0200https://site.fredlab.dev/blog/from-csv-to-agent-tabular-data-gets-smart-in-fred/Fred now supports agentic access to tabular data like CSV and Excel through a new DuckDB-based backend and the Tessa agent. Explore how this works and what it unlocks.https://site.fredlab.dev/blog/expanding-fred-with-mcp-a-playground-for-next-gen-agentic-architectures/Mon, 19 May 2025 12:00:00 +0200https://site.fredlab.dev/blog/expanding-fred-with-mcp-a-playground-for-next-gen-agentic-architectures/Fred is now capable of serving and consuming components over the Model Context Protocol (MCP). Discover how this unlocks new architectures and makes Fred a live testbed for building interoperable AI agents.https://site.fredlab.dev/blog/introducing-the-new-fred-architecture-modular-agentic-and-knowledge-aware/Wed, 07 May 2025 16:27:22 +0200https://site.fredlab.dev/blog/introducing-the-new-fred-architecture-modular-agentic-and-knowledge-aware/Fred is now composed of three modular components: a React UI, an agentic backend using LangGraph, and a knowledge-centric backend for document processing. Learn how it all fits together.
