OpenAIs First Custom AI Chip Is Here — And Its Called Jalapeño - Memeburn
Summary
OpenAI and Broadcom unveiled Jalapeño, OpenAI’s first custom AI chip built for inference workloads. The chip moved from design to manufacturing in nine months and is already running lab workloads, including GPT-5.3-Codex-Spark. OpenAI claims the chip can cut inference costs by about 50%, but those numbers are self-reported and still need independent verification. Deployment starts with small prototype volume in late 2026 and is expected to ramp through 2027–2029, which could reshape OpenAI’s compute economics and reduce reliance on NVIDIA.
