The full stack behind abundant intelligence

OpenAI's compute strategy focuses on an integrated system spanning data centers, chips, frontier models, developer platforms, consumer and enterprise products, and AI-native devices, with each layer reinforcing the others. Jalapeño, OpenAI's first custom inference chip, outperforms commercial systems in peak tokens per kilowatt throughput and lower token latency using GPT-OSS 120B on the InferenceX benchmark, and also excels on DeepSeek R1 and Kimi K2. This increased computational efficiency allows OpenAI to serve more customers at a lower cost, funding future research and development.

This report marks the first time OpenAI has shared measured performance results for its custom inference chip, Jalapeño, showing it outperforms commercial systems on key benchmarks.
