OpenAI Partners With Cerebras For 750 MW Computing Power Deal Through 2028

• According to a report from CNBC that cited people close to the company, the deal is worth over $10 billion. 
• Cerebras said that the partnership was a decade in the making, with teams of both companies having met frequently since 2017 to share research and other work. 
• Cerebras is an artificial intelligence company that builds Wafer-Scale Engines (WSEs) designed to train and run generative AI models that are touted to respond up to 15 times faster than GPU-based systems.

ChatGPT’s OpenAI and AI chipmaker Cerebras Systems on Wednesday announced that they have signed a 750 megawatts multi-year computing power agreement.

Both companies announced the plans on their websites. The deployment will roll out in multiple stages starting in 2026 and make it the largest high-speed AI inference deployment in the world, Cerebras said.

Meanwhile, OpenAI said in its statement that capacity will go online in multiple tranches through 2028.

Deal Contours

According to a report from CNBC that cited people close to the company, the deal is worth over $10 billion.

Cerebras said that the partnership was a decade in the making, with teams having met frequently since 2017 to share research. Under the deal, Cerebras will deploy its wafer-scale systems to serve OpenAI customers.

“For Cerebras, 2026 is shaping up to be an extraordinary year. In collaborating with OpenAI, the wafer-scale technology we pioneered will reach hundreds of millions—and eventually billions—of users,” the company said.

“OpenAI’s compute strategy is to build a resilient portfolio that matches the right systems to the right workloads. Cerebras adds a dedicated low-latency inference solution to our platform. That means faster responses, more natural interactions, and a stronger foundation to scale real-time AI to many more people,” said Sachin Katti, who works with OpenAI’s compute infrastructure.

What Is Cerebras?

Cerebras is an artificial intelligence company that positions itself as a high-speed solution for AI. The company builds Wafer-Scale Engines (WSEs) or large processors designed to train and run generative AI models touted to provide responses up to 15 times faster than GPU-based systems.

This makes Cerebras a competitor to companies like Nvidia Corp. (NVDA), which provides GPU-based solutions and is the largest semiconductor company in the world.

Earlier, Bloomberg reported, citing a person familiar with the matter, that Cerebras was in talks to raise about $1 billion in a new funding round, valuing it at $22 billion before the investment. The company was still planning to pursue an initial public offering, as per the report.

Cerebras filed for an IPO with the U.S. Securities and Exchange Commission in 2024, without a set share price or expected market cap. The company was expected to go public in 2025, but withdrew its plans in October 2025.
