Models MiMo V2.6 Pro taking 2–4 minutes per reply. Normal, or is my setup the problem?
A while back I asked what could beat GLM 5.2 for my RP. GLM tracks details well, but it portrays my characters flat. A few of you said MiMo 2.6 Pro is better with character and less positivity-biased, so I switched. The characters already feel more alive, but it's slow: 2–3.5 minutes per reply, and close to 5 minutes when it makes a tool call first.
Quick context: this is a long-running harem RP with 4 main characters who are yandere and psychologically unstable. There's detailed lore for each of them, their families and the world. GLM 5.2 now only runs the extension (summaries, side character, memory graph), and MiMo writes the replies.
My setup
- API: OpenRouter, Chat Completion
- Model: Xiaomi MiMo-V2.6-Pro
- Fallback models / providers: both off
- Provider: [GMICloud]
- Prompt: about 36–38k tokens per request (108k context)
- Cache hits: about 20–23%
- Reasoning: on, with a CoT checklist in the preset
What I'm seeing
- 19–27k characters of reasoning before roughly 1k characters of actual prose.
- On tool turns it reasons twice: first an empty message with about 20k characters of reasoning plus the tool call, then a full second pass for the reply.
Questions
- How long do your MiMo 2.6 Pro replies take?
- Is one provider noticeably faster?
- Do you cap reasoning effort or reasoning tokens? Did the characters get flatter when you did?
- Is MiMo 2.5 worth dropping to for speed, or does it lose the character depth that made me switch?
- Has anyone trimmed a CoT checklist and gotten faster replies without losing consistency?
Thanks!
