# OpenAI's Jalapeño Inference Chip Beats Nvidia Blackwell on Performance Per Watt

> OpenAI walked into Hot Chips on August 25 with benchmarks for Jalapeño, its first serious custom inference chip, and the numbers were aimed straight at Nvidia. On interactive chatbot-style workloads the company claimed 1.5 to 1.9 times better energy efficiency and 2.1 to 4.1 times lower latency than Nvidia's Blackwell, the part that currently underpins much of the industry. The caveats matter. Jalapeño only handles inference, the running of already-trained models, and leaves training firmly in Nvidia's court. It was built with Broadcom and is only headed for low-volume production late this year, so it will not dent Nvidia's order book any time soon. Still, the direction is clear. Every large model company is now trying to escape the Nvidia tax on the workload that actually costs them money day to day, which is serving billions of chat responses. If OpenAI can really cut the power bill on inference by a third or more, it changes the economics of running its own products and gives it leverage it has never had over its most important supplier.
