Whether you're a seasoned developer or a beginner, this guide aims to equip you with the knowledge and steps necessary to overcome this hurdle.

Understanding the Error: Model Not Accessible

The core issue presented in the error message is that the specified model, gpt-5.1-codex, is not accessible through the /chat/completions endpoint. This typically indicates a mismatch between the model being requested and the API endpoint being used. Several factors can contribute to this incompatibility. Let's delve deeper into the potential causes.

Common Causes for Model Inaccessibility

  • Incorrect Endpoint Usage: The /chat/completions endpoint is designed for models that support conversational AI, often involving a back-and-forth dialogue format. If gpt-5.1-codex is not a model intended for this type of interaction, using this endpoint will result in an error. It's crucial to verify the intended use case of the model and select the appropriate API endpoint.
  • Model Deprecation or Updates: Models can be deprecated or updated over time. If gpt-5.1-codex is an older model, it may no longer be supported on the /chat/completions endpoint. Reviewing the API documentation or release notes can shed light on any changes in model availability.
  • Account Permissions and Access: Access to specific models might be restricted based on your account type or subscription plan. Ensure that your account has the necessary permissions to utilize gpt-5.1-codex on the chosen endpoint. Contacting the API provider's support team can clarify any access-related limitations.
  • API Version Incompatibility: Using an outdated API version might lead to incompatibility with newer models or features. Always strive to use the latest stable version of the API to avoid such issues. Check the API documentation for the most recent version and update your code accordingly.
  • Extension or Software Bugs: Although less common, bugs within the extension (version 0.29.1 in this case) or VS Code itself (version 1.102.3) could trigger unexpected errors. Updating to the latest versions of both the extension and VS Code can often resolve these software-related glitches.
