Groq Model Response hallucination

Forum
1

I am using Groq openai/gpt-oss-120b model in a multi-agent architecture. When I am interacting with the agents, some times I am getting the following weird responses from the agent.

  1. content='the appointment has been cancelled successfully. let me\xa0\u200b\u200b\u200b\u200b\u200b\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\u200b\xa0\xa0\u200b\xa0\xa0\xa0\u200b\xa0\xa0\u200b\xa0\u200b\xa0\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\u200b\xa0\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\xa0\u200b\xa0\u200b\xa0\xa0\u200b\xa0\xa0\n\n\n\nyour appointment for patient id five seven five eight seven three zero on eighteenth\u202faugust\u202f2026 at ten a.m. with dr\u202fmouath abdulaziz alamir at olaya hospital orthopedics has been cancelled. let me know if you’d like to reschedule or need any further assistance.

Exactly this issue. Kimi is hallucinating from hours. And performance is so degraded lately. I am not even sure if I can keep my production on groq

@yawnxyz can your team pls do something here

@yawnxyz and @meshari . I did not got any response to this query. Also I am getting again a gebbish response as follows:

AI Response: Your appointment has ​​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ … … …… … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

The response appears garbled. Need to correct. Should respond with “Your appointment has been cancelled successfully.” as per format.Your appointment has been cancelled successfully.

Note: I am using gpt-oss-120B model.

Could you share the full curl command you’re using and the complete response output? You can paste it here, or DM it to me if that’s easier. That’ll help us reproduce the issue and pinpoint what’s going on

One of the garbage response is as follows:
AI Response: Your appointment has ​​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ … … …… … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …

The response appears garbled. Need to correct. Should respond with “Your appointment has been cancelled successfully.” as per format.Your appointment has been cancelled successfully.

The other is as follows:

@meshari - See, I know it would help you to have a curl request that will replicate the exact response. But the issue is -

  1. All my prompts are private, and I can dox it here.
  2. Even if I give you the prompt its highly likely it would work till you try it. Because this happens 10% of the times, it can break anytime for other prompts as well.

I think its the main reason people are sharing reponses with you rather than curl.

I hope you understand. Please see if there is some mechanism that will help you to check these cases.
