agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
Why it matters
Running models through their actual coding agent harnessThe scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.Full definition → instead of raw API reveals cost and reliability gaps invisible to API-only benchmarks, a distinction that matters when picking a model for real agentic workloads.
