# gemma-4-26B-A4B-it Q4_0 on Ryzen AI Max+ 395 (llama.cpp Vulkan) — answerless (empty) responses in default mode: 8.3 % of requests

On a Beelink GTR9 Pro — AMD Ryzen AI Max+ 395, Radeon 8060S (gfx1151), 128 GB LPDDR5X-8000 unified running llama.cpp (server, Vulkan backend), b9049 (server_fingerprint b9049-2496f9c14) with ggml-org/gemma-4-26B-A4B-it-GGUF @ bb4531cda34d (Q4_0), the measured answerless (empty) responses in default mode was 8.3 % of requests (share of all issued requests). The measurement was taken under the frozen interactive-assistant-v2@2026-08-02 workload; evidence level lab_repeated, 3 valid runs across 1 physical unit. The value is re-derived from the raw run records on every CI build.

## Statement

> In its default operating mode at a 1024-token budget, this share of everyday requests returned HTTP 200 with an empty answer: the reasoning pass consumed the entire budget. A second model family reproduces the failure mode.

**Limitations.** Three repeated runs on one unit. Default operating mode of the model (reasoning emitted); disabling reasoning via the chat template was not tested for this model family.
