AI is happening. The future is updating.GLM-5.3-Flash-MXFP4
An MXFP4 GLM-5.3-Flash checkpoint for text and image-to-text serving on AMD Instinct MI355X (gfx950). On matched text-reasoning samples against amd/GLM-5.3-Flash-Quark-MXFP4, it scores **+1.0 percentage point on MMLU** and **+3.5 points on GPQA Diamond**, with **−0.2 point on GSM8K**. These are observed differences on fixed samples, not statistically established superiority or a claim about vision, safety, or general agentic quality. Runtime support: SGLang PR #39273. Both checkpoints answered the same fixed questions with one greedy attempt per question. A capped or unfinished response counts as incorrect.
