+| **Solar Pro 4**             | Full access             | Limited-time trial; 524K context, text only                       |

 Most models draw on your normal daily sessions rather than a separate limit. GLM 5.3 Flash is the exception, capped at 2 sessions a day while we measure what it costs at scale. MiMo 2.5 stays unmetered and costs no session at all. Models may still serve from a quantized (Q8_0) build.

 大多数模型使用你的常规每日会话，而不再各自设限。GLM 5.3 Flash 是例外：在我们评估其规模化成本期间，每天限用 2 次会话。MiMo 2.5 保持无限使用，完全不消耗会话。模型仍可能由量化（Q8_0）版本提供服务。
