No — GLM-4.7-Flash at Q4 needs ≈ 18.46 GB even at 4K context, beyond the RTX 5080 16GB's 16 GB GDDR7. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 423.2 tok/s (estimated, batch 1). FP16 needs ≈ 64.0 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. Methodology.

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).
