OpenAI has signed a multi-year AI computing deal worth more than US$10 billion with Cerebras Systems, marking one of the largest infrastructure commitments yet in the global race to scale artificial intelligence.
The agreement will give OpenAI access to 750 megawatts of AI computing power, built in stages through 2028 and hosted by Cerebras, according to a joint statement.
What’s in the Deal
Scale: 750MW of AI compute capacity
Duration: Multi-year, through 2028
Estimated value: > US$10 billion
Purpose: Faster inference and response times for AI models, including ChatGPT
OpenAI said the partnership will significantly improve speed and responsiveness, a critical factor as AI usage scales globally.
“This partnership will make ChatGPT not just the most capable but also the fastest AI platform in the world,”— Greg Brockman, President and Co-founder, OpenAI
Why Cerebras Matters
Cerebras uses giant, wafer-scale chips designed specifically for AI workloads, taking a different architectural approach from traditional GPUs.
Focused on high-speed inference, not just training
Operates its own data centres to demonstrate performance and generate recurring revenue
Aims to challenge Nvidia in selected AI workloads
Recent testing showed Cerebras hardware running OpenAI’s GPT-OSS-120B model up to 15 times faster than conventional systems.
This deal positions Cerebras to capture a meaningful share of the tens of billions of dollars being poured into AI infrastructure worldwide.
OpenAI’s Expanding AI Compute Stack
The Cerebras agreement adds to a string of massive infrastructure commitments by OpenAI:
Nvidia: Up to US$100bn AI infrastructure investment (announced Sept)
Advanced Micro Devices: Deployment of 6GW of GPUs over multiple years
Broadcom: Partnering with OpenAI on custom AI chip development
Together, these moves reflect an unprecedented bet on sustained, long-term demand for AI compute.
Cerebras IPO Angle
The OpenAI deal also strengthens Cerebras’ capital markets story:
In talks to raise ~US$1 billion in new funding
Potential pre-money valuation of ~US$22 billion
Preparations underway for a possible IPO
CEO Andrew Feldman said the agreement “launches high-speed inference into the mainstream,” pushing Cerebras into the top tier of AI infrastructure providers.
Investment Takeaway
This deal reinforces three major AI trends:
Inference is becoming as critical as training
AI infrastructure demand remains far from peaking
Alternative chip architectures are gaining real traction
For investors, the OpenAI–Cerebras partnership underscores that the AI boom is no longer just about models — it is increasingly about who controls speed, scale, and power-efficient compute.
