What the Qwen3.8-Flash-Next-REAP-256-duo numbers mean

The fastest verified result on our board is 53.5 output tok/s on an RTX 3090 x2 at Unsloth-Dynamic-Q3_K_XL with a 32768-token context. That is about 18.7 ms per generated token — 500 tokens takes roughly 9.3 seconds. Prompt processing on the same record runs at 948.6 tok/s, so a 2,000-token prompt is read in about 2.1 seconds. Peak VRAM was measured at 33.9 GB.

How much VRAM does Qwen3.8-Flash-Next-REAP-256-duo need?

Qwen3.8-Flash-Next-REAP-256-duo has 180.0B 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)	117.2 GB	141 GB
Q8_0 (8-bit)	220.7 GB	multi-GPU or CPU offload
FP16 (16-bit)	414.8 GB	multi-GPU or CPU offload

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.
