Can RTX 4070 12GB run GLM-4.7-Flash?

NVIDIA · 12 GB GDDR6X · 504 GB/s bandwidth · Z.ai · 31.2B (active 3B) · MoE · model ctx up to 198K

No — GLM-4.7-Flash at Q4 needs ≈ 18.46 GB even at 4K context, beyond the RTX 4070 12GB's 12 GB GDDR6X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 125.0 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	18.46 GB	No	129.1 est.
Q4	8K default	18.76 GB	No	125.0 est.
Q4	32K	20.56 GB	No	104.1 est.
FP16	4K	63.7 GB	No	—
FP16	8K default	64.0 GB	No	—
FP16	32K	65.8 GB	No	—

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).
