How to use this comparison
Writing/long output: Prioritize median output tok/s and peak speed.
Chat/agents: TTFT usually has a bigger UX impact.
Model selection: Rerun your real Prompt and inspect output quality too.
FAQ
Which model outputs faster, k3 or step-3.7-flash?
step-3.7-flash has faster output (median 170 vs 33 tok/s); step-3.7-flash has faster TTFT (1.99s vs 4.61s).
Why can output speed and TTFT have different winners?
Output tok/s measures sustained generation speed, while TTFT measures the wait until the first token. A model can generate long text faster while still taking longer to start.
How should I rerun this comparison?
Use the arena with the same Prompt, temperature and network conditions, then repeat a few times and combine the speed data with output quality.
