Halo
Ben BachemHalo, the Langfuse assistant, is now in public beta for everyone on Langfuse Cloud. Ask questions about your traces, observations, and metrics in plain language.
Halo, the Langfuse assistant, is now available to everyone on Langfuse Cloud. No opt-in, no Feature Preview modal. Open it and start asking questions about your data.
Ask in plain language. For example:
- "Which traces had the highest latency yesterday?"
- "Show me failed generations in the last hour."
- "What's my token spend this week, broken down by model?"
How it works
Halo runs on the Langfuse MCP server, the same MCP server you can connect to your own tools. It uses those tools to query your traces, observations, and metrics, then answers in context.
This is the initial release. More capabilities will follow.
Halo is Langfuse Cloud only and still labeled Beta. It is free during the Beta, though pricing may change later.
