OpenAI's First Chip, Jalapeño, Takes Aim at NVIDIA's Inference Margins
OpenAI unveiled Jalapeño, its first custom chip: an inference-only chip designed in-house and built with Broadcom, scaled over Ethernet rather than NVLink, with OpenAI's own models helping design it. OpenAI claims significantly better performance per watt than current hardware, but the chip is still in testing and it shared no TFLOPS, HBM capacity, power, or confirmed node. We separate what's confirmed from what's still marketing.
