In this project we will build a Python banking assistant agent using Strands Agents and make it observable and continuously evaluated using Langfuse โ step by step. - Source: dev.to / 4 days ago
Langfuse is the open-source standard for LLM observability. It traces every LLM interaction โ prompts, completions, latency, token usage, cost โ and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / 23 days ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / about 1 month ago
Gateway or proxy attribution. A reverse proxy in front of the model-provider API records the request, computes the cost, and exposes per-customer breakdowns. Open-source options include Helicone, LiteLLM, Langfuse, and OpenLLMetry. Hosted equivalents serve as the AI cost observability layer for teams that want centralized visibility: LangSmith, Datadog LLM Observability, Arize Phoenix.

So, I reviewed the questions list again but this time, since the time I did view it about 9 hours ago [1]. 10 were negative scored, 5 positive scored, 15 0 scored, 4 has received answers. This is better than normal for those ~30. Usually it's 80% without votes, without answers, without comments. So, this is a significan improvement...

It's surely both. Look at the newest questions: https://stackoverflow.com/questions?tab=Newest Most questions have negative karma. Even if somehow that is "deserved", that's not a healthy ecosystem. All that is left of SI are clueless questioners and bitter, jaded responders. SO worked when "everyone" was new to it, and they felt energized to ask questions ( even "basic" questions, because they hadn't been asked... - Source: Hacker News / 6 months ago
