NVFP4 / INT4 tradeoffs with PyTorch - pixelspark - 10-12-2026

Thought I'd post a small recipe because a lot of threads ask similar things.

This isn't revolutionary, but the combination of SGLang and A6000 felt surprisingly usable once I tuned around quant drift.

Maybe useful as a starting point for newer folks.

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