If we're measuring progress in hours and days then yes. But if we're measuring progress in months then OSS models are doing fine. You can get a state-of-the art performance in an open model if you pretend it is January 2026 instead of June.

There is no evidence here that the cutting edge labs have any durable advantage. Extrapolating current trends it seems likely that even the Europeans will be capable of meeting any given performance measure with enough time. In fact the evidence suggests that the capital required to run the models is where a moat will develop. Knowing the weights won't help much.
