When can we expect merged DeepSeek V4 Flash / MiniMax M3 llama.cpp support?

I am relatively new here, I have little experience in how long support development takes. I know there are forks. But not merged status means AFAIK that support is far from perfect.

When can we expect stable full support for DeepSeek V4 Flash and/or MiniMax M3 in llama.cpp?

Alternatively, are there any other tools that have such support already? E.g. I have not tried vLLM at all, only used llama.cpp and koboldcpp.

TIA
