It builds simulated work environments modeled on real jobs and studies how frontier agents fail inside them — particularly when an agent technically finishes a task but misses unstated requirements — then turns those findings into training data to improve model behavior. Its earlier LLM evaluation platform, including its API, SDK, evaluators, Lynx, GLIDER and Percival, is retired and no longer offered.","category":"AI & Automation","decision_record":{"best_for":"Frontier AI labs and enterprise teams that need agentic reinforcement-learning environments, simulation infrastructure and post-training data for agent behavior. Also a fit for organizations with proprietary data interested in licensing it to Patronus AI for research and training.","not_ideal_for":"Teams looking for a ready-to-use LLM evaluation SaaS, API or SDK: the prior evaluation platform and its tools are retired and new users cannot sign up. Buyers wanting transparent published pricing, a self-serve tier, a public trial, or consumer/SMB tooling will not find one here.","problems_solved":["Agents technically complete tasks but miss the point, cut corners or skip unstated requirements — failures conventional ","Agent behavior is hard to diagnose because real working environments have fragmented information, conflicting user reque","Teams need controlled environments where agent failures can be surfaced and studied before deployment.","Model developers need post-training data targeted at judgment and behavioral reliability, not just task accuracy.","Organizations with proprietary data have no clear, published path for licensing it into research and training."],"pricing":"No public pricing, plan table or self-serve purchase path is published.

Preserve the key limitation that the former LLM evaluation platform, its API, SDK, evaluators, Lynx, GLIDER and Percival are retired and new users cannot sign up. Preserve the cost facts: no published pricing, no self-serve tier, commercial terms and data-licensing economics undisclosed, and never describe the offering as free. Do not use legacy press or case studies describing the evaluation product as current evidence.
