OpenAI announced the preliminary test results for its first custom inference chip, Jalapeño. Data indicates that compared to baseline systems, the chip delivers a 1.5x to 1.9x increase in peak performance per watt across models including GPT-OSS 120B, DeepSeek R1 670B, and Kimi K2.5 1T, while reducing end-to-end latency by 1.7x to 3.6x; under high-interaction workloads, performance improvements reach 2.1x to 4.1x.
