OpenAI首款自研芯片Jalapeño通过Broadcom合作推出

OpenAI rolls out its 1st chip through a Broadcom tie-up as part of its “build the full stack” push.

Jalapeño is an ASIC, so it is less flexible than an Nvidia GPU, but can be cheaper and faster when the workload is known very well.

They say "the architecture reduces data movement and balances compute, memory, and networking resources to achieve realized utilization much closer to theoretical peak performance."

Overall better performance per watt.

Jalapeño also signals OpenAI’s shift from buying compute to shaping the whole stack: models, software, servers, networks, and now silicon.

There was a 9-month tape-out, means OpenAI and Broadcom finalized the chip design and moved it to manufacturing unusually fast for advanced AI silicon.

OpenAI says its own models helped speed up parts of the design work.
