OpenAI is building internal software that lets its AI workloads run across hardware from multiple manufacturers, a direct challenge to Nvidia’s near-monopoly on the infrastructure powering modern artificial intelligence.

The effort centers on creating low-level platform primitives, essentially the foundational code that tells different chips how to handle the same AI tasks.

The multi-vendor playbook

This isn’t just a software project. OpenAI is pairing its internal tooling with major hardware partnerships designed to give it real alternatives to Nvidia’s ecosystem.

In October 2025, OpenAI formalized a multi-year partnership with Broadcom focused on co-developing accelerator and networking systems. That same month, the company signed a deal with AMD to deploy up to 6 gigawatts of AMD Instinct GPUs, with deployment starting in the second half of 2026.
