Moonshot launches Kimi K3.1 Pro with updated pricing and reasoning features

By PulseAugur Editorial · [1 sources] ·

Moonshot has released Kimi K3.1 Pro, an updated version of its Kimi K3 model, with pricing adjustments and new technical considerations. The new model is available through the Kimi app, Kimi Code, and API, with pricing reduced by approximately one-third compared to Kimi K3.
