# OpenAI pairs its Jalapeño AI chips with AMD EPYC Turin hosts

*2026-10-02 · Source: [Tom's Hardware](https://www.tomshardware.com/pc-components/cpus/openais-jalapeno-asics-are-deployed-alongside-amd-epyc-turin-cpus-as-hosts-hardware-vp-says-nvidias-vera-standalone-is-a-little-bit-behind-on-that-maturity-level)*

OpenAI is deploying rack-scale systems of its in-house Jalapeño ASIC (application-specific integrated circuit) with AMD EPYC 'Turin' CPUs as host processors. It did not choose newer agent-oriented chips such as Arm's AGI or Nvidia's Vera.

**Why it matters:** Host CPU choice shows where OpenAI's custom-silicon stack is going: it is betting on proven x86 hosts rather than the new agentic CPU wave. It also gives AMD a data-center win in the same week it claimed its Venice CPUs beat Nvidia's Vera, and signals Nvidia's CPU push faces resistance even from its biggest customers.
