-fa offis required — flash attention breaks the vision path on gfx1151.14.34 GiB · 14.08 tok/s on a Ryzen AI MAX+ 395.
Phi-4-Reasoning-Vision-15B — ROCmFPX 8-bit AGENT GGUF
An 8-bit ROCmFPX quantization for AMD gfx1151 (Ryzen AI MAX+ 395 / Strix Halo), quantized from BF16 GGUF — a lossless source, not a requantization of a lower-bit build.

⛔ Requires a llama.cpp with the ROCmFPX quant types
Q8_0_ROCMFPX (111) and Q8_0_ROCMFPX_AGENT (115) exist only in
charlie12345/ROCmFPX. Stock llama.cpp reports
invalid ggml type 103. Ignore the auto-generated "Use this model" commands above.
All quant variants
Three builds, all measured in one session on one box with one binary (Ryzen AI MAX+ 395,
gfx1151, ROCm 7.2.4, ROCmFPX-2809dc5, -fa off) — so these rows are directly comparable.
Median of 3, warm-up discarded, otherwise-idle box.

| 8-bit AGENT | 115 | 14.34 GiB | 8.40 | 14.08 | 14.06 – 14.09 | link |

⚠️ The 4-bit build is ~1.7× faster and 43% smaller. The 8-bit builds exist for accuracy
headroom, not throughput. The two 8-bit builds are within noise of each other (14.08 vs
14.15, ranges touching) — this model has no MTP draft head, and AGENT's benefit shows up in
draft acceptance, so there is nothing here for it to win.
⚠️ -fa off is mandatory — flash attention breaks the vision path on gfx1151.
The BF16 mmproj (862 MiB) ships in every one of these repos and is required for vision.
Correctness: 17×23 ⇒ ✅ 391 · capital of Japan ⇒ ✅ Tokyo · days in 2024 ⇒ ✅ 366
Give this model room to reason. On a curt "reply with only the number" prompt it can answer
365for the 2024 question; allowed to reason it correctly derives leap year ⇒366.
What was NOT measured
- No perplexity run, and no quality A/B against the source. The checks above are memorized-fact prompts — necessary but not sufficient.
- No long-context testing. · No tool-calling evaluation.
- Vision was smoke-tested only (the 4-bit build correctly describes an 8×8 red PNG as
Red); no vision benchmark was run on these 8-bit builds.
