OpenAI Taps Cerebras for GPT-5.3 Codex Spark in Bid to Loosen Nvidia’s Grip
OpenAI's new coding model is its first major step to break free from Nvidia's grip.
Deep Dive
OpenAI is releasing GPT-5.3 Codex Spark, its first AI model powered by chips from Nvidia rival Cerebras. The $10 billion deal-backed model is designed for real-time, interactive coding edits and will be available in ChatGPT. This marks a strategic push by OpenAI to diversify its chip supply chain away from Nvidia, alongside other partnerships with AMD and Broadcom, despite still planning massive Nvidia deployments.
Why It Matters
This signals a major industry shift to challenge Nvidia's AI chip monopoly, which could reshape costs and availability for all developers.
