OpenAI’s Jalapeño chip boosts AI speed and cuts power use

Quantum ZeitgeistAugust 26, 20265 min read

OpenAI’s Jalapeño inference chip delivers industry-leading speed and efficiency, serving up to 1.9x more AI work per watt.

OpenAI reports its first custom inference chip, Jalapeño, can serve more AI work per unit of power while also returning responses more quickly. Jalapeño delivers both higher throughput and lower latency with one architecture, a feature often requiring tradeoffs in existing hardware systems. The chip achieves this efficiency across GPT‑OSS 120B, DeepSeek R1, and Kimi K2.5 1T, delivering 1.5 to 1.9 times more AI work per watt at peak throughput and 1.7 to 3.6 times lower end-to-end latency than comparison systems. For highly interactive workloads, it delivered 2.1 to 4.1 times higher performance. OpenAI…
