To gain more initiative in the computing power battlefield, OpenAI is accelerating its "de-NVIDIA" strategy. On February 12, 2026, OpenAI officially launched its first AI model based on Cerebras Systems chips - GPT-5.3-Codex-Spark.

The "Lightning" Evolution of Programming Experience

As a productivity tool specifically designed for software engineers, GPT-5.3-Codex-Spark brings a more flexible interaction mode:

Instant Interruption and Switching: Developers can interrupt long-running computational processes at any time, without waiting, and instruct the model to switch to handle other urgent coding tasks.

Full-Process Coverage: The model can assist engineers in quickly completing high-frequency operations such as editing specific code segments and running automated tests.

A $10 Billion Bet on Non-Standard Computing Power

This model release marks the first milestone after OpenAI and Cerebras entered into a deep partnership.

Expensive Agreement: The two parties have signed a multi-year agreement worth over 10 billion dollars, aiming to achieve ultra-large-scale computing power deployment of 750 megawatts.

Long-Term Strategy: The related production capacity will be rolled out in phases, with the full hardware deployment expected to be completed by 2028.

Industry Insight:

As AI competition enters deeper waters, a single chip supply channel has become a bottleneck restricting the development of major players. By supporting Cerebras and running core models on its hardware, OpenAI not only achieved breakthroughs at the technical level but also secured a "card" to free itself from NVIDIA's constraints at the strategic level.
