OpenAI's Secret Weapon: AI-Designed 'Jalapeno' Chip Taped Out
thehiphopswami · x · 2026-08-30
Key Rumor: SemiAnalysis reports that OpenAI's secret weapon, the in-house "Jalapeno" chip, has taped out. Allegedly designed by AI, it reportedly beats NVIDIA Rubin on tokens-per-megawatt and was developed in just nine months.
Discussion Points:
- Performance comparison between Jalapeno, Rubin, and GB300 (specifically within InferenceX).
- Why tokens-per-megawatt is the critical metric.
- Samsung's HBM4 comeback.
- AI-written RTL and kernels.
- Is the CUDA moat draining?
- Next up: Anthropic's ASIC.
