Kimi, the chatbot from Moonshot AI, apologized to paying users for speed limitations and unjustified quota consumption when using the new K3.1 Pro model. The company decided to return part of each subscriber's monthly limit.
The company announced this early on October 26, according to sources IT Home and National Business Daily. In its statement, Kimi admitted that the problem was the company's fault and should have been resolved sooner.
As compensation, Kimi announced a one-time reset for all subscribers across all subscription tiers. Every active user will receive a refund equivalent to 25% of their total monthly quota, which is equivalent to about a week of usage. Users who used less than 25% of their quota will receive a reset of their usage to zero. Kimi specified that the adjusted values will be displayed in user usage indicators by the end of the day.
Furthermore, the company announced a configuration change that includes reducing unnecessary sub-agent calls and shortening output lengths. This will allow the same quota to perform more real tasks. The reason for the quota consumption issue was that in workflows simulating agent operation, one request could trigger multiple sub-agents and long responses, each consuming the user's limit.
These apologies came two days after Moonshot AI released K3.1 Pro on October 24 as the first model in the K3.1 series. The company positions it as its most powerful model to date, boasting around 3 trillion parameters and a context window of 1 million tokens. A high-speed version is also available, generating responses two to three times faster. The models are available on kimi.com, the Kimi app, Kimi Work, Kimi Code, and via the Kimi API. Moonshot AI plans to release the full model weights by November 4. The company reported a score of 65.7% on Terminal-Bench 4.0, a test for coding agents in real terminal environments, which is a self-reported figure.
Previously, Kimi had faced capacity overload. In July, shortly after launching K3, the company temporarily suspended new consumer subscriptions because demand exceeded available computing power.
