  • How to change an LLM prompt in production without a code deploy
    Langfuse is the other serious option in this category if you also want observability, evals and traces bundled with prompt management. Different scope, more setup, worth comparing honestly. - Source: dev.to / 20 days ago
  • Should Your Prompt Store Pick Your Model
    Langfuse with Microsoft.Extensions.AI has an appealing story: update prompts without redeploying. A prompt fetches its config blob—model, tokens, temperature—which the code passes straight to the LLM. - Source: dev.to / 23 days ago
  • The Observability Crisis: Why OTel Alone Fails for AI and How to Build a Resilient Pipeline
    Langfuse is not a replacement for OpenTelemetry; it is a specialization layer built on top of it. Langfuse was engineered specifically for the unique telemetry needs of LLM applications. It acts as the semantic layer that OTel lacks. - Source: dev.to / 28 days ago
