Enhancement: Deepseek prefix completion (prefill)

What features would you like to see added?

Deepseek models are possible to be prefilled just like Claude! As far as I know it's even possible to prefill it's thoughts.
Please consider implementing it, it would be a huge help and this way we could use it's full capability with control over even it's thoughts!

With deepseek-r1 this can be EXTREMELY useful. Many reports on twitter show that injecting specific thoughts can help the model escape local optima.
