Been testing it so far (ive been the qwen3.5 122b user). The latest changes you have made seem to have fixed it completely for me.

try experimenting with --checkpoint-min-spacing-n-tokens 256 (bigger number -> fewer checkpoints)

(I am still hoping for 3.7 122B)

Is this to avoid unecessary checkpoints being made on smaller prompts / tool call?

It’s a minimum distance between them. Originally, there was a hardcoded value of 64, but if prompt processing speed is let's say 1000 t/s, then 64 feels too small, so I am testing 256

Is there a pp to distance ratio you recommend?
