Jalapeño Inference Chip

OpenAI's first custom chip — a reticle-sized ASIC built from scratch for LLM inference (not a repurposed accelerator) that delivers substantially better performance-per-watt by minimizing data movement; co-developed to tape-out in ~9 months with help from OpenAI's own models, deployment starting late 2026.
