OpenAI Deploys In-House Jalapeño ASIC with AMD Turin Hosts

KEY FACTS

  • OpenAI has deployed its in-house Jalapeño ASIC internally.
  • The chip runs alongside AMD EPYC Turin hosts equipped with 1.5TB of memory.
  • OpenAI hardware lead Richard Ho said the choice of Turin was a pragmatic one.
  • Ho noted that Nvidia's new Vera CPU is slightly behind in maturity.
  • Jalapeño is currently limited to internal use at OpenAI, with no plans for external sales.

PHYSIX OBSERVATION

OpenAI's in-house chip has landed, yet it chose AMD over an Nvidia CPU, showing it values deployment speed and engineering controllability more. This sends a signal: AI giants are using in-house ASICs to reduce dependence on Nvidia, but ecosystem maturity remains a key variable, and Nvidia's position will be hard to shake in the short term.
