By far the biggest announcement at the 37th Hot Chips conference was OpenAI’s stunning progress on their own chip, less than a year after the Broadcom announcement… and that it isn’t an ASIC; but a full on Blackwell-beating alternative.The key metric now is shifting to performance per watt, and Jalapeno delivers:The full Hot Chips presentation is not yet out but various takes are below.

In OpenAI’s tests, Jalapeño delivered 1.5–1.9× more work per watt at peak throughput and 1.7–3.6× lower end-to-end latency, with 2.1–4.1× higher performance for highly interactive workloads; the chip is rated at 700W but reportedly stayed at or below 550W on the tested runs. OpenAI says deployment into its own infrastructure begins by year-end, with Gen 2 already deep in development and Gen 3 underway (OpenAI announcement, deployment roadmap, Sam Altman).Why engineers care: the claim is not just raw perf, but a more balanced inference architecture that reduces …
