Yes, but it is tight — EXAONE 3.5 32B at Q4_K_M needs about 22.3 GB of the 24 GB usable on RTX 4090 Desktop (24 GB VRAM, 64 GB RAM), leaving only ~1.7 GB before the runtime starts swapping. Expect ~34.2 tok/s (estimated), with room for about 8,192 tokens of context.

Q4_K_M — it needs about 22.3 GB of the 24 GB available, downloads as roughly 19.3 GB, and runs at an estimated 34.2 tokens/sec with up to 8K of context.
Nothing binding — the model fits with headroom and generates at a usable speed on this hardware.
