OpenAI Is Working With SoftBank’s Arm on AI Chip Effort

OpenAI’s development of its own artificial intelligence chip could end up benefiting SoftBank, one of its biggest shareholders, which is also helping the ChatGPT maker develop and finance its ambitious data center plan.

OpenAI is talking with SoftBank’s Arm subsidiary about using an Arm-designed central processing unit with OpenAI’s AI server chip, according to three people close to Arm. OpenAI is co-designing its AI chip with Broadcom, and Arm hopes OpenAI will also use the CPU with other AI chips from Nvidia and AMD, one of these people said.
