Oh shit, I took a closer look and you’re right. The repo was also helpfully updated with a note to this effect: “The Accelerate framework is actually currently unused since I found that for tensor shapes typical for the Decoder, there is no benefit compared to the ARM_NEON intrinsics implementation. Of course, it's possible that I simlpy don't know how to utilize it properly. But in any case, you can even disable it with LLAMA_NO_ACCELERATE=1 make and the performance will be the same, since no BLAS calls are invoked by the current implementation”.

No Joi in my pocket just yet :(

Because of this I re-checked my claims about the Whisper speed up from the Neural Engine and that does look legit, 6x at least. So the Neural Engine does have the chops for this workload, it just isn’t being used in this repo. It may not be LLaMA, but I sure hope someone gets an LLM running on the ANE sooner rather than later.
