Model for long-running tasks hit novel failures and was pulled from internal use

During limited internal use of a model trained for long-running tasks, the team found novel failures that were not caught by existing pre-deployment evaluations, so access was paused.
The key takeaway is that long-horizon behavior can surface failure modes standard evals miss, making this a concrete safety and deployment lesson rather than a generic model update.
