This issue might be a duplicate of existing issues. Please check:

  • #8851: Kimi-K2 via OpenRouter fails with tool call tokens inside thinking block
  • #6253: Kimi K2 on Zen keeps adding ':' colon before commands or file names
  • #6598: KimiK2-thinking fails at subagent call

Feel free to ignore if none of these address your specific case.
