B.AI said Moonshot AI's latest preview model, Kimi K2.8 Preview, is now live and available to developers through both API and Web Chat. According to ChainCatcher, the model is designed for coding and agent workflows and supports a 1M-token context window, along with text, image, and video multimodal input.

It is also said to deliver performance close to the flagship Kimi K3, improve reasoning efficiency and coding capability versus K2.7 Code, and offer adjustable Low, High, and Max inference modes. Developers can access Kimi K2.8 Preview through the B.AI platform starting now.
