What the Qwen3.5-4B-MTP numbers mean

The fastest verified result on our board is 240.4 output tok/s on an RTX 3090 at Q6_K_XL with a 24576-token context. That is about 4.2 ms per generated token — 500 tokens takes roughly 2.1 seconds. Prompt processing on the same record runs at 2167.6 tok/s, so a 2,000-token prompt is read in about 0.9 seconds. Peak VRAM was measured at 5.6 GB.

How much VRAM does Qwen3.5-4B-MTP need?

Qwen3.5-4B-MTP has 4.0B 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.
