What the MobileLLM-125M numbers mean
The fastest verified result on our board is 1271.3 output tok/s on an RTX PRO 6000 Blackwell at Q8_0 with a 4608-token context. That is about 0.8 ms per generated token — 500 tokens takes roughly 0.4 seconds. Prompt processing on the same record runs at 138696.6 tok/s, so a 2,000-token prompt is read in about 0.0 seconds. Peak VRAM was measured at 1.0 GB.
How much VRAM does MobileLLM-125M need?
MobileLLM-125M has 0.1B parameters. These estimates use the same formula as the VRAM calculator: weights, plus about 15% for a moderate-context KV cache and runtime overhead, plus a small engine floor.
| Quantisation | Estimated VRAM | Smallest card that fits |
|---|---|---|
| Q4_K_M (4-bit) | 0.9 GB | 8 GB |
| Q8_0 (8-bit) | 1.0 GB | 8 GB |
| FP16 (16-bit) | 1.1 GB | 8 GB |
