Kimi K3 Developer Suspends New Sign-Ups After Demand Surges Sixfold

My take: Kimi K3 demand multiplied sixfold in under 48 hours and Moonshot AI's infrastructure could not absorb it. The company halted new sign-ups while rebuilding capacity; existing subscribers are not affected.

What this says goes beyond simple popularity. It signals real, active, and growing demand for open-weight models that compete directly with Western frontrunners. A 2.8-trillion-parameter model built in China hitting GPU limits this fast, forcing a pause on new registrations, is not a marketing accident — it is the market responding to real capability.

On July 27, Kimi K3's full weights are set to be released, making it the largest open-weight model published to date. Once that happens, any company or team with sufficient infrastructure will be able to run it internally, without depending on Moonshot's API.

Does your organization have the infrastructure capacity to take advantage of frontier-scale open-weight models, or are you still depending exclusively on third-party APIs?
