OpenAI unveils its first custom chip, built by Broadcom

OpenAI finally showed its own chip: Jalapeño, an inference processor designed and manufactured with Broadcom. OpenAI says its own models helped design it. Early testing shows much better performance-per-watt than current alternatives. The post doesn't give specific numbers, a production timeline, or which products will use it. I'd discount the hype for now—going from testing to mass deployment usually takes a long time, and it's unclear how much cost this saves versus sticking with NVIDIA.

Why it matters: OpenAI's first custom chip is a watershed moment, but the post lacks key numbers — no performance delta, no timeline, no cost comparison — capping it at 78. HKR all hit, enough for featured, but the info density isn't there for 85+.
