On February 13, 2026, OpenAI officially launched its first AI model, GPT-5.3-Codex-Spark, powered by Cerebras Systems' chips. This model is a lightweight yet faster version of the Codex code automation software, designed to compete with companies like Google and Anthropic in the AI programming assistant market. GPT-5.3-Codex-Spark enables software engineers to swiftly complete tasks such as code editing and running tests, while supporting the ability to pause or switch tasks at any time. To enhance the model's response speed, OpenAI had previously signed a hardware usage agreement with Cerebras worth over $10 billion.
