GLM 5.3 Flash, Gemini 3.7 Flash, and Qwen3.8 Flash followed at 0.69, each at substantially lower cost.** By [RuntimeWire Staff](/author/runtimewire-staff) · Published ### Leaderboard | Rank | Model | Mean score | Est. cost/task | |---|---|---|---| | 1 | Claude Opus 5 (Fast) | 0.73 | $0.0460 | | 2 | Z.ai: GLM 5.3 Flash | 0.69 | $0.0003 | | 3 | Google: Gemini 3.7 Flash | 0.69 | $0.0014 | | 4 | Qwen: Qwen3.8 Flash | 0.69 | $0.0005 | | 5 | step-3.7-flash | 0.59 | — | ### 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. Reasoning effort was pinned to **max** for every model whose lane exposes a control (OpenAI-style `reasoning_effort` , Anthropic extended thinking, Gemini thinking config). Models marked *vendor default* on the interactive board expose no such control and ran as shipped. 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.
