OpenAI has unveiled Jalapeño, its first in-house inference chip, developed with Broadcom and Celestica under the leadership of a former Google TPU core member. Tailored for models like ChatGPT, it set a record for fastest ASIC tape-out and is scheduled for deployment by late 2026 with superior energy efficiency.

## At a glance

- Led by a former Google TPU member, Jalapeño set a record with tape-out in just 270 days
- Optimized for models like ChatGPT, it will deploy in late 2026 with leading energy efficiency

## The update

OpenAI has officially launched Jalapeño, its first self-developed inference acceleration chip. Led by Richard Ho, a former core expert of Google's TPU team, the project was manufactured in collaboration with Broadcom and Celestica. Jalapeño is custom-built for large models such as ChatGPT and Codex, aiming to improve actual utilization by optimizing data movement and resource balance. Taking only 270 days from design to tape-out, it set a new record for the fastest development of high-performance ASICs. The chip reportedly offers significantly better performance per watt than current mainstream solutions and is scheduled for deployment by late 2026 to support more efficient AI inference services.
