    LLM Observability using Langfuse

    Date: Mar 12 2024

    Summary: It was good to see a tool which provides indepth analysis of LLM model interactions. This will be very useful in development and production.

    Positive: I like that this is exclusively designed for LLMs only, so it takes a lot of clutter out of having to deal with features to do with rest of the models. Scores are very comprehensive including the ones related to query/response, ability to find rag relevance, cost related metrics which other tools typically do not offer and comprehensive trace function.

    Negative: There wasn't much but if I have to highlight something here, self hosting was difficult. And the main dashboard can have drill downs to take it to relevant sections in traces/generations etc
