Laminar’s RL-trained model finds agent-trace errors at 23 times lower cost
Laminar says its flow-1 model matches GPT-6-sol on its trace-error benchmark while costing 23 times less, making full production-trace analysis more affordable. Teams evaluating agent observability should examine how the benchmark and cost comparison hold up.
- What
- • Laminar's flow-1 is an RL-trained model designed to find errors in AI-agent traces.
- How
- • It inspects trace spans through the Signals harness, returns findings as signal events, then groups similar events into clusters.
- Why it matters
- • The authors say its cost makes analyzing every production trace feasible, supporting failure discovery and eval datasets without sampling.
