Summary by WebProNews
OpenAI just dropped hard numbers on its first custom AI processor. The chip, called Jalapeño, claims striking gains over Nvidia’s latest systems in power efficiency and response speed. But the real story runs deeper than any single benchmark. At the Hot Chips conference, OpenAI’s hardware chief Richard Ho presented results that turn heads. On three open models — GPT-OSS 120B, DeepSeek R1 670B, and Moonshot’s Kimi K2.5 1T — Jalapeño delivered 1.5…

OpenAI and Broadcom have developed the Jalapeño chip to optimize the inference of large language models (LLM). This chip surpasses the current solutions of Nvidia and AMD thanks to a generalist architecture focusing on energy efficiency and exceptional performance/watt ratio. The development has been accelerated by the use of AI for hardware design and automatic generation of software kernels via Codex. With Jalapeño, OpenAI calls into question …

OpenAI advances in the design of its own processors with Jalapeño, but Jensen Huang argues that Nvidia retains decisive advantages in scale, supply and technology. *** Jensen Huang stated that he does not personally take the development of Jalapeño and defended Nvidia’s ability to compete. OpenAI said that his inference chip exceeded Nvidia’s GB300 in response speed and energy efficiency, according to his own tests. Nvidia reported revenues of U…
