Langfuse AI Gateway is in public beta for companies that want a single entry point for OpenAI and Anthropic traffic, so they can track cost and govern who can call which models. An app or coding agent changes its base URL and uses a gateway key instead of a provider key. Requests stay in the provider's native format, and no SDK or code change is required. Provider keys remain in Langfuse, so a team can issue and revoke access without sharing credentials. The launch is aimed at model use that existing tracing misses. Coding agents, internal assistants, and scripts are rarely instrumented, so platform and finance teams cannot see who called which model or what it cost. Admins approve models centrally and issue keys to people or services, optionally tagged with a team or cost center. By default the gateway records metadata, usage, and cost, not prompt content. With full logging on, each call becomes a Langfuse trace that can be searched and evaluated with the rest of the platform. The core gateway is MIT-licensed and can be self-hosted next to an existing Langfuse deployment, or used on Langfuse Cloud. Cloud is available in the EU, US, JP, and HIPAA regions. Langfuse is the open source AI engineering platform co-founded by Marc Klingen, Max Deichmann, and Clemens Rawert, and has been part of ClickHouse since January 2026. The beta supports OpenAI and Anthropic. Support for additional providers, plus spend limits, fallbacks, and guardrails, is on the roadmap.
