Kimi K3.1 Pro starts rolling out on Kimi web and mobile

Moonshot's Kimi K3.1 Pro is appearing in the Kimi web and mobile apps, according to TestingCatalog, which posted a screenshot where the app describes it as "Complex tasks and professional work, all-around flagship." Other X accounts (LuminaBench, AiBattle_, ai_for_success) report the same, and say K3.1 Pro and a K3.1 Pro Highspeed variant are also in the Kimi Code CLI. No official Moonshot post was seen when these reports were made.

One user, notjazii, posted rough API prices: K3.1 Pro at $1.94 per million input tokens and $10.15 per million output tokens, and Highspeed at $3.88 and $20.30. They say this is about 35% cheaper on input and 32% cheaper on output than K3, and that their first test ran at about 100 tokens per second. These figures are the user's, not Moonshot's.

The rollout follows a teaser video the day before, when Moonshot had not yet announced the model.
