Curious what people here are seeing.
I'm mostly working with Phi in PyTorch on A6000. The part I'm trying to understand is VRAM headroom.
Would appreciate practical advice rather than theory.

I hit almost the same issue last night. At this point the real bottleneck is my patience.

A couple things I'd check first. On Threadripper box, the easiest win is often to back off the aggressive settings and see whether the problem survives. A lot of these threads end up being one bad config plus a pile of conclusions drawn from it.

Thanks, that helps. I don't think your conclusion is far off. I got better results once I stopped chasing one metric and just looked at whether the workflow felt usable.

Tried to reproduce it just now. I couldn't reproduce the slowdown until I pushed context much higher. The main thing that moved was latency, not quality.

I don't think that's the whole story. I get why that seems right, but on B200 the bottleneck felt elsewhere. Not saying you're wrong, just that I wouldn't lock that in as the lesson yet.

What worked for me was pretty simple. Start by verifying the driver/runtime combo, then test with a smaller prompt, then look at quant drift.

I'd start with the simpler stack.
