  • Strands Agents + Langfuse Evaluations
    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 / about 1 month ago
  • Best AI Monitoring Tools in 2026: LLM, Agent, and MCP Observability Compared
    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 / about 2 months ago
  • What is an LLM evaluation harness? A deep dive into lm-eval-harness
    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 / 2 months ago
  • How to track LLM costs per customer in production
    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.

    Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ€” the metadata.userId pattern is the universal part. - Source: dev.to / 2 months ago
