@katopz I tried openthaigpt-1.0.0-beta-13b-chat with both the curl command you provided and reproduced the error. According to the investigation, the issue should be caused by the curl command. It contains special characters. The following snapshot presents the comparison between the curl command (red circle) mentioned in this issue and the one (blue circle) we created. You can try the one we created on your local system. If any further issues, please let us know. Thanks!
