@rekram1-node, I had this at least 4 times today and few times yesterday. I thought it was a fluke first but now it is happening frequently.

@rekram1-node here is the example: https://opncd.ai/share/jG3Zt7Gd

I started a new session in the OpenCode source code and just asked "What is this code about", then it started hallucinating

Hi @rekram1-node,

I am sorry for bothering. I really wanted to use the Kimi K2 Thinking as my testing target. This bug is blocking me from using it.

The issue is random, and most probably because of the model behavior. I suspect, if you are using OpenRouter, then one of the providers setup and different.

I contacted our inference provider, not much I can do on our end but if it continues to be unresolved ill see if I can do something else to fix it
