Mistral (Non-Tekken), i.e., Mistral v3 + `[SYSTEM_PROMPT]`

Looks like `<think>` doesn't need to be prefilled. You can opt out of reasoning - it's just as good, maybe even better.

No toxic data so you may want to prefill / guide reasoning when dealing with heavy themes (unless your prompt is sufficiently instructed/gaslit to be evil).

Alternatively, since `<think>` is not a special token, you can influence reasoning by phrasing it like `<evil_think>`, `<creative_think>`, or `<spicy_think>`, etc. It's smart enough to close it properly.

Yes, this is how much I want to avoid tuning MoEs.
