Open-Weights Frontier

The open-weights frontier is the rolling subset of publicly downloadable model weights whose benchmark performance is within one generation of the best closed model available.

Why It Matters

A closing open-weights gap caps how much rent any closed lab can extract per token, and shifts defensibility from model quality to distribution, data, and deployment.
