Chinese AI model Kimi K3, which triggered US tech sell-off, halts new sign-ups

Chinese AI startup Moonshot has paused new subscriptions for its Kimi K3 model after excessive demand pushed its capacity close to the limit. "We're adding capacity as fast as we can and will reopen new subscription spots in batches," Moonshot said. Kimi recently triggered a sell-off in US technology stocks after claiming performance on par with Anthropic's and OpenAI's models.
