What the LFM2.5-1.2B-Instruct numbers mean

The fastest verified result on our board is 709.5 output tok/s on an RTX 3090 at Q4_K_M with a 24576-token context. That is about 1.4 ms per generated token — 500 tokens takes roughly 0.7 seconds. Prompt processing on the same record runs at 11527.5 tok/s, so a 2,000-token prompt is read in about 0.2 seconds. Peak VRAM was measured at 2.4 GB.

How much VRAM does LFM2.5-1.2B-Instruct need?

LFM2.5-1.2B-Instruct has 1.0B 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.

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.
