Sunday Coffee & Code: Agent 6 is online, RAG improvements are on their way.

Less time available this week than usual but still have progress.

By Steve Harris

Less time available this week than usual but still have progress. ● Agent 6: Finished up Agent 6 that takes the initial response and the QA input and creates an updated version. Used the orchestrated set of agents this week to respond to an RFP - completed in under 2hrs and submitted (will be interesting to see the results). ● High Risk/High Friction: In the process of preparing the final version I realised there is room for another agent to prepare an even more polished version and also that this is as far as I would likely take it. An RFP or Proposal is on the high risk/high friction end of the spectrum and human input is definitely required prior to submission. ● RAG: Improvements are underway. LightRAG is installed and running, creating data stores and knowledge graphs (snippet below). Couple of issues to work on - Server UI isn’t replying using knowledge in the knowledge base (pretty fundamental - not sure if this is just the GUI version or not - will test programmatically) - There may be a bug for embedding models that don’t use 1024 dimensions (to be confirmed - https://lnkd.in/ghMdvEjQ). - Ollama doesn’t seem to support re-rankers - will have to look at other solutions for this (switch to vLLM or maybe just go all-in on hosted models). All in all some good progress and a lot learned. Next on the roadmap: - Further testing on LightRAG and re-ranker decisions. - Agent 007?
