What the LFM2.5-230M numbers mean
The fastest verified result on our board is 520.0 output tok/s on an Radeon AI Pro R9700 at MQ4 with a 4096-token context. That is about 1.9 ms per generated token — 500 tokens takes roughly 1.0 seconds. Across the 3 records we hold for this model the range is 226.3–520.0 tok/s on 3 GPUs, because quantisation, context length and the engine build all move the number.
How much VRAM does LFM2.5-230M need?
LFM2.5-230M has 0.2B 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) | 1.1 GB | 8 GB |
| FP16 (16-bit) | 1.3 GB | 8 GB |
