How to choose

- Output-heavy work (long-form writing, long answers): qwen3.8-max has the lower output price (¥72 vs ¥95.19 per 1M tokens).
- When you resend the same long prefix (a fixed system prompt, the same long document), cached input is billed at the cache-read price: qwen3.8-max ¥3, kimi-k3.1-pro ¥1.82 (per 1M tokens).
- Both support Chat Completions, so requests look the same and switching means changing the model parameter (the key's groups must offer both models).
How to call them
Both models work with a Tutujin API key: set your SDK's base_url to https://www.tutujin.com/v1 and use the model name; everything else is written as with the official SDK.
