how to connect continue to LLMs from GitHub Models Marketplace ?

[fabse-hack]

Hello,

how i can connect models from:
https://github.com/marketplace?type=models

i test gpt 5:
https://github.com/marketplace/models/azure-openai/gpt-5
(the apiBase is the new url from github, since a few month)

to continue?

i try it already a few times:

name: Local Config
version: 1.0.0
schema: v1
models:
  - name: GPT-5
    model: openai/gpt-5
    provider: openai
    apiBase: https://models.github.ai/inference
    apiKey: my_GITHUB_TOKEN

but i get the error:
Unexpected non-whitespace character after JSON at position 4 (line 1 column 5)

here is the error log:

        }
      ],
      "messageOptions": {
        "precompiled": true
      }
    }
  }
}

SyntaxError: Unexpected non-whitespace character after JSON at position 4 (line 1 column 5)

so, what is wrong???

solution:

name: Local Config
version: 1.0.0
schema: v1
models:
  - name: GPT-5 via GitHub
    provider: openrouter
    model: openai/gpt-5-chat
    apiBase: https://models.github.ai/inference
    apiKey: <NEUER_TOKEN>
    requestOptions:
      headers:
        X-GitHub-Api-Version: "2022-11-28"

From my point of view, the error suggests Continue is treating the GitHub Models response as if it were a standard OpenAI payload when there are still provider-specific differences in endpoint behavior or response framing. That is why a config that looks syntactically reasonable can still explode during parsing.

The clean fix is either a first-class GitHub Models provider preset or a documented compatibility layer, not trial and error with the generic openai provider.
