Laminar releases flow-1, an RL model that catches silent agent failures

What the research found

Laminar released flow-1, an RL-trained open-source-based model that detects errors in agent traces, claimed to match GPT-6-sol detection quality at 23x lower cost.

Claims and how well the evidence supports them

1. flow-1 matches GPT-6-sol in detection quality while being 23x cheaper 98%
2. Laminar is open-source observability for AI agents since 2024 98%
3. flow-1 was post-trained with RL on thousands of synthetic agent investigations 99%
4. Signals harness treats each trace span as a file and returns JSON signal events 99%
