The mystery model that topped OpenRouter's charts as "Ox Alpha" has been unmasked: it was z.ai's GLM 5.3 Flash all along, and the weights are now open. Nick and Jack break down why it's basically Opus 4.8 you can run at home, the 15-cent-per-million pricing that explains why it was free, and the new pre-training approach that lets it run on Chinese chips. Then: Apple's M5 Ultra Mac Studio with 512GB of unified memory, whether that's enough to run GLM 5.3 locally, how fast it would be, and whether local inference is finally worth it. Plus: Stacked is taking a sponsor and giving the money to viewers, a first look at Stacked Bench (draw Arnold in SVG), DeepSeek's peak pricing, DGX Spark, the Elon question, and the most insane people Nick and Jack have ever met.
