Moonshot AI Announces End of Service for First-Generation Trillion-Parameter Multimodal Model Kimi K2.5 at Month-End

Moonshot AI has officially announced that its first-generation trillion-parameter multimodal model, Kimi K2.5, will cease service at the end of this month. This marks the official end of the model's lifecycle on official channels, and users will no longer be able to call this version through the original interface.

Kimi K2.5 was released and open-sourced in January of this year and was once considered Moonshot AI's smartest model at the time. It demonstrated top-level performance in the open-source domain on general intelligence tasks such as Agent, code generation, and image and video processing, and adopted a native multimodal architecture.

Rapid iteration of large models is an industry norm, and the retirement of old versions usually means that a new generation model is about to or has already taken over. This retirement reflects the acceleration of AI technology updates and also tests the open-source community's capability to maintain and migrate old version models.
