What the LFM2-8B-A1B numbers mean

The fastest verified result on our board is 18.3 output tok/s on an GTX 1060 x2 at Q4_K_M with a 2048-token context. That is about 54.6 ms per generated token — 500 tokens takes roughly 27.3 seconds. Prompt processing on the same record runs at 13.5 tok/s, so a 2,000-token prompt is read in about 148.1 seconds. Peak VRAM was measured at 1.1 GB.

How much VRAM does LFM2-8B-A1B need?

LFM2-8B-A1B has 8.0B 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)	6.0 GB	8 GB
Q8_0 (8-bit)	10.6 GB	16 GB
FP16 (16-bit)	19.2 GB	24 GB

Long contexts and large batches raise the real number — read the smallest card as "possible with a reduced context". Measured throughput is on the benchmark board.
