Additional Information
Slack where this was reported

[azan-baloch]

There old endpoint is not supported now and returns 410 Gone status. Now they have new endpoint https://router.huggingface.co/v1/chat/completions.

Also now request body format has changed,

{
  "model":"openai/gpt-oss-120b",
  "messages":[
    {"role":"user","content":"Hello!"}
  ],
  "stream":false
}

and now their response contains an array of choices, to get cotent we have to use this

response.choices[0].message.content
