The ATOM Report provides updated analysis of the open language model ecosystem using the Relative Adoption Metric (RAM), a novel methodology for measuring model adoption in a time-varying, size-normalized manner. The report examines GPT-OSS growth, inference market share dynamics, Chinese mid-tier models like Moonshot and Z.ai, and Gemma 4's strong early adoption. The work supports strategic investment in U.S. open models.
