Facing the same issue

Hello SONG Ge @sgwhat
Is there any information about when this might appear in supported models?

[sgwhat]

Not sure. I am not working on developing it recently.

[kodiconnect]

The fix was added to an August release of ollama, so I'm guessing we have to wait for the now seemingly defunct intel team to roll in the ollama fix into IPEX. I'm thinking this project is on the back burner or they fired the talented staff that was working on this.

@kodiconnect unfortunately, yes. This is the end of ipex-llm.
I have 60 t/s on a single A770 with llama.cpp (vulkan).
And FA is working in b7063

Go to the OpenArc community, there is a SYCL maintainer.
