What the Qwen2.5-0.5B-Instruct numbers mean

The fastest verified result on our board is 1060.0 output tok/s on an RTX PRO 6000 Blackwell at Q8_0 with a 4608-token context. That is about 0.9 ms per generated token — 500 tokens takes roughly 0.5 seconds. Prompt processing on the same record runs at 116339.6 tok/s, so a 2,000-token prompt is read in about 0.0 seconds. Peak VRAM was measured at 1.8 GB.

How much VRAM does Qwen2.5-0.5B-Instruct need?

Qwen2.5-0.5B-Instruct has 0.5B 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.
