langfuse: AI engineering insights
Develops and operates large-language-models with tools for evaluation, observability, and metrics.
"A founder uses langfuse to monitor LLM performance and optimize it for better results. First, they install langfuse and set up OpenTelemetry for metrics and observability. Next, they create a prompt management system and configure it to integrate with the LLM. Finally, they run a series of tests to fine-tune the model's performance. With langfuse, they're able to scale their LLM operations efficiently and make data-driven decisions."
- •When you need to monitor and optimize the performance of your LLMs
- •When you want to manage and version your prompts and datasets for LLMs
- •When you need to integrate your LLMs with other tools and platforms like OpenTelemetry, Langchain, or OpenAI SDK
Run 'npm run eval -- --model <your-llm-model> --prompt <your-prompt-text>' to evaluate your LLM's performance on a specific prompt

Langfuse: AI engineering insights is a very large TypeScript project (~585k lines across 4317 code files, plus 444 test files). It is a full software project: use it through its install path rather than reading it end to end. Last commit this month, Other license, has a test suite.
