This seems like more competition for Cerebras? Am I understanding correctly?

This is just an uncut wafer - I don't think it's intended to be a wafer-scale chip.

Cerebras etch memory onto the wafer alongside the processing elements, but AFAIK OpenAI are going to be using HBM memory and a conventional chiplet design.

Still competition for cerebras. Seems quite unlikely they will get an OpenAI deal anytime soon.

No - this is OpenAI trying to complete with Google (TPU) and Amazon/Anthropic (Trainium) on cost.

Cerebras are addressing a very specific use cases, not general purpose LLM serving, and OpenAI does already partner with them.
