No — Kimi-K2.6 at Q4 needs ≈ 570.7 GB even at 4K context, beyond the RTX 4090D 24GB (China)'s 24 GB GDDR6X. It would only run with heavy CPU/disk offload. FP16 needs ≈ 2067.4 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
