About Langfuse
Langfuse helps teams develop, monitor, evaluate and debug AI applications: it ingests traces of LLM calls, retrieval, embeddings and agent actions, runs evaluations, manages prompts and datasets, and integrates with the major LLM SDKs and frameworks. It can be self-hosted or used as Langfuse Cloud, and has been part of ClickHouse since January 2026. Most of the code is MIT-licensed; enterprise directories carry a separate licence.
Full Langfuse profile →About PZERO
PZERO documents agent-facing inference APIs and a hosted MCP interface for text, image and video requests. Its public models API returned a model catalogue during review. Authenticated requests use an API key and prepaid USDC balance; the MCP connection can spend that balance. No account, wallet, payment or inference was executed. Availability, model quality and provider routing were not benchmarked.
