At the end of 2025, OpenAI, Anthropic, and xAI collectively utilized only about 21% of the global operational AI compute, despite the existence of approximately 16 million deployed H100-equivalents and 20 million sold H100-equivalents. This highlights a significant gap in usage versus availability, as the production and sales of advanced AI accelerators have generated a substantial global inventory that currently exceeds the immediate operational needs of leading labs.

xAI: xAI focuses on AI systems aimed at advancing scientific understanding, including through its Grok models. The organization is referenced in the EpochAI data for its role within the small group of frontier labs driving only a portion of total AI compute operations.
OpenAI: OpenAI develops and deploys advanced generative AI models and related applications as a leading AI research organization. The company appears in the EpochAI analysis as one of three frontier labs whose combined usage represents a modest share of worldwide operational AI compute.
EpochAI: EpochAI tracks and publishes data on AI progress, with emphasis on compute resources, model capabilities, and industry trends. The group serves as the direct source of the analysis examining compute utilization by OpenAI, Anthropic, and xAI at the end of 2025.
Anthropic: Anthropic builds reliable and interpretable AI systems, primarily through its Claude model family. It is included in the report as a key participant among labs whose aggregate compute consumption remains limited relative to global capacity.
