Kimi K2 Thinking Turbo is listed as a discontinued API model in Kimi’s official catalog. Publisher sources identify no separate Turbo model card or weight release; they point to the distinct Thinking checkpoint with 1 trillion total parameters, 32 billion active parameters, long context, and tool calls.
Moonshot’s catalog marks kimi-k2-thinking-turbo as discontinued from May 25, 2026. The underlying open model card is Kimi K2 Thinking, so the service label and weights remain separate.
