Frequently asked questions about LLMs

Real answers from real users, pulled straight from launch discussions, forums, and reviews.

  • Claude often keeps nuance and coherence across long sessions, but reviewers note message limits and search can still constrain truly deep project threads. In production teams typically combine three practices:

    • Pick a model that preserves long-context reasoning (Claude is praised for this) and be aware of its message/window limits.
    • Instrument and iterate with tools like Langfuse to trace conversations, run prompt experiments, and scale event storage so you can reproduce and debug long sessions.
    • Compare and validate behavior across models in real traffic (as some use ChatGPT for live comparative analysis).

    Monitor traces, iterate prompts, and plan infra for larger traces to keep long-context features reliable in production.

  • Langfuse supports open integrations, so connecting LLMs to vector DBs for RAG is straightforward using existing tooling. Key points:

    • Use integration docs and quickstarts to wire embeddings + vector stores and a retrieval step into your model pipeline.
    • Tools like Langchain provide quickstarts and helpers to get a retrieval-augmented flow running fast.
    • Langfuse can also monitor and evaluate multiple providers (OpenAI, Google, Anthropic) from one dashboard, which helps debug and tune RAG setups.

    Start with the Langfuse integrations page and a Langchain quickstart to prototype quickly.
