I was able to use rope/yarn scaling with llama.cpp to extend the context window to 256K and it seems to be pretty usable on the debugging-and-bugfixing session I have that’s 216K tokens deep. No infinite output loops, reasoning is still coherent, tool calls appear to be passing and failing at roughly the same rate as a fresh context window. Haven’t tried going to 512K or higher yet but 256K definitely seems usable to me on a single Radeon R9700.

I added these arguments to my llama-server call, using the official GGUF release from Meta’s account on HF.
