## Summary

[Openai](/ar/entity/openai) signed a multi-year deal with wafer-scale chipmaker Cerebras for 750MW of low-latency inference compute valued above $20bn, disclosed in Cerebras's first quarterly report as a public company. Cerebras posted $193.4m in Q1 revenue, up 94% from a year earlier, and added a parallel partnership with [Amazon](/ar/entity/amazon)'s AWS to distribute its CS-3 systems globally. The company raised $6.4bn in what it calls the largest semiconductor IPO ever. The deal diversifies OpenAI's compute away from [Nvidia](/ar/entity/nvidia) GPUs toward custom silicon built for inference speed.

## Why it matters

OpenAI is spreading its compute book across vendors as inference, not training, becomes the cost center. Cerebras's single-chip design targets the latency that conventional GPU clusters struggle with, giving OpenAI faster real-time responses and giving a second-source supplier real scale against Nvidia.

## What to watch

- Whether the 750MW deploys on schedule given grid and power constraints.
- How much of OpenAI's inference shifts off Nvidia hardware.
- Whether Cerebras's revenue ramp justifies its post-IPO valuation.
