What it does
Kimi K2.5 was one of the models offered through the Kimi API Platform, and the platform's model list now marks it as deprecated. According to that page, it was officially discontinued on 31 August 2026 and is no longer maintained or supported. The page directs users to kimi-k3 as the replacement, describing it as the vendor's most capable model, with 2.8 trillion parameters, native visual understanding and a 1M-token context window. The list also keeps kimi-k2.7-code, a coding-focused model with a high-speed variant, and kimi-k2.6, which accepts visual and text input and supports thinking and non-thinking modes. The older moonshot-v1 family was retired on the same date, and earlier kimi-k2 variants were retired in May 2026. An integration that still calls kimi-k2.5 needs to move to a current model; the platform documentation includes migration guidance and guides for tool calls, streaming, JSON mode, vision input and context caching.
