Jalapeño at 700 watts against the 1,400-watt GB300 point in the same SemiAnalysis tables is the number OpenAI wanted in one frame. 216 GB of HBM4, 13.4 MXFP4 petaFLOPS, Broadcom on the tape-out. Treat the 1.5 to 1.9 times throughput-per-watt claims as OpenAI’s, with a slide behind them. Volume in 2027, trickle later this year.
