Step 5 Preview, a mixture-of-experts model from Chinese AI company StepFun with a 1-million-token context window, has been listed on OpenRouter, the platform that aggregates access to multiple AI models. The listing suggests StepFun is expanding availability of its flagship model to international developers, who can now test it alongside models from OpenAI, Anthropic and Google.

Why now: A major new large-context Chinese model becoming accessible through a popular API aggregator is notable news for developers tracking the global AI race.
