Can Tesla P4 8GB run gpt-oss-120b?

NVIDIA · 8 GB GDDR5 · 192 GB/s bandwidth · OpenAI · 120.4B (active 5.1B) · MoE · model ctx up to 128K

CUDA

No — gpt-oss-120b at Q4 needs ≈ 67.73 GB even at 4K context, beyond the Tesla P4 8GB's 8 GB GDDR5. It would only run with heavy CPU/disk offload. FP16 needs ≈ 242.82 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	67.73 GB	No	—
Q4	8K default	68.24 GB	No	—
Q4	32K	71.3 GB	No	—
FP16	4K	242.31 GB	No	—
FP16	8K default	242.82 GB	No	—
FP16	32K	245.88 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).
