### How we scored it

Every model answered the same 50-task battery from **Newsroom Reliability v0.2**, one task at a time, with no tools and no retries on content.

50 open-ended tasks were graded 0–10 by gpt-5.4 against a fixed rubric — blind to which model wrote the answer — and normalized to the same 0–1 scale.

A model's **mean score** averages its graded tasks; a generation failure counts as 0. **Cost per task** is estimated from each model's published per-token pricing ("—" where pricing isn't public), so treat it as directional, not billing-exact.
