 These limits are **temporary**, and they exist because the providers serving DeepSeek now charge more than free mode can carry. V4 Pro is one session a day; GPT-5.6 Luna is two sessions a day; models may serve from a quantized (Q8_0) build. MiMo 2.5 stays unlimited. All of it is intended to be reverted.
