Grok Models

How to Connect Grok

The recommended way to call Grok models is usually through the OpenAI-compatible API:

POST /v1/chat/completions

That means:

• Base URL is still https://logox.top
• Route is still /v1/chat/completions
• The main change is setting model to a Grok model name

Query Available Models Through new-api

curl https://logox.top/v1/models \
  -H "Authorization: Bearer sk-logox-your-key"

Native xAI Query Method

curl https://api.x.ai/v1/models \
  -H "Authorization: Bearer $XAI_API_KEY"

Common Current Text Models

• grok-4.20

      { "role": "user", "content": "Give me a product announcement title" }
    ]
  }'

Note

If GET /v1/models does not show Grok models, the current token's group has not assigned them, or token model permissions filtered them out.
