Post-Training Delivery Benchmark Tests LLM Agents as Forward-Deployed Engineers
The benchmark reframes agent evaluation around deliverable outcomes and payment-gated acceptance, a shift from metric-chasing benchmarks that miss corrupted training runs. Teams building or buying post-training-as-a-service can use the acceptance gate and corruption detector to screen automated fine-tuning pipelines. The human FDE baseline gives a concrete performance reference against all four frontier agents.
