What the Phi-4-reasoning-plus numbers mean

The fastest result on our board is 92.3 output tok/s on an RTX 5090 at Q8_0 with a 2048-token context. That is about 10.8 ms per generated token — 500 tokens takes roughly 5.4 seconds. Prompt processing on the same record runs at 7981.6 tok/s, so a 2,000-token prompt is read in about 0.3 seconds.

How much VRAM does Phi-4-reasoning-plus need?

Phi-4-reasoning-plus has 15.0B 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.
