 "answer": "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 needle retrieval success was 95.8 % of requests (share of all needle requests). The measurement was taken under the frozen long-context-v1@2026-08-03 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.",
