omnia vs langfuse

We already trace everything in Langfuse.

Keep it. Omnia’s traces go to Langfuse as standard OpenTelemetry. What Langfuse leaves to you is acting on what it sees: holding a version back, rolling one back, refusing a tool call.

An online evaluator flags a jump in wrong answers.

on omnia

That version was on part of the traffic, as every new version is. The same metrics stopped its promotion and rolled it back, and its failing sessions became regression scenarios. docs

on langfuse

Online evaluation scores live traces as they arrive. Langfuse describes its role as ex-post evaluation, and points to other libraries for run-time measures. their docs

Scores that move traffic

Evaluations score live sessions, and the rollout reads those scores. Promotion and rollback follow from them automatically. docs enterprise

Langfuse: Online evaluators score traces as they arrive; acting on the score is up to you. source

Simulated users, built in

Simulated users ship with the platform and run against each version through its real tools, hostile and duplex voice callers included. The release waits on the suite. docs

Langfuse: Simulated multi-turn conversations are a cookbook built on the OpenEvals library. source

Policy before the tool runs

Each tool call’s arguments and caller are checked against a CEL rule first. Named fields in the response are redacted before the model reads it. docs enterprise

Langfuse: Run-time security is left to separate libraries. source
