OpenAI has unveiled 'Jalapeño,' its first self-designed inference chip, benchmarked by SemiAnalysis. Developed with Broadcom in just 16 months, the chip outperforms Nvidia Blackwell, AMD, and Google in TCO and throughput across multiple open-source models. The deep dive covers architectural details and hardware-software co-design strategies, revealing Jalapeño as a generalized high-performance inference chip rather than one specialized solely for OpenAI models.
