OpenAI's New Chip Beats Nvidia in Independent Speed Test

At Hot Chips on August 25, 2026, OpenAI shared first results for Jalapeño, a custom chip it built with Broadcom to run AI models. On an independent test by SemiAnalysis, Jalapeño generated more AI text per user and used less power per unit of work than a comparable Nvidia Blackwell system. Limited rollout starts late 2026, broader in 2027.
