Why does my VSCode extension respond as ChatGPT3 instead of GPT-4?

Below is an explanation of what might be happening:

Possible Reasons for the "ChatGPT3" Response

1. Extension Defaulting to an Older Model
   Many VSCode extensions for ChatGPT use the OpenAI API to generate completions. Even if you’ve set the extension to use GPT-4, the extension might default to GPT-3.5 (often referred to as “ChatGPT3”) if:

   • The extension’s configuration isn’t correctly updated.
   • The extension doesn’t support GPT-4 via the API.
   • There’s a fallback mechanism when the requested GPT-4 resource isn’t available.

2. Model Specification in the API Request
   The OpenAI API requires you to specify the desired model (for example, "model": "gpt-4" or "gpt-4o" in some examples). If the extension isn’t sending the correct model name or if there’s an internal misconfiguration, the API call might actually be using GPT-3.5 (often represented internally as a ChatGPT3 variant).

3. Extension Version or API Key Issues
   Even if you have a ChatGPT Plus subscription (that provides access to GPT-4 from the website), using the API via extensions requires:

   • An API key with proper permissions.
   • Correct endpoint and model configuration.
     Some extensions might still be using their default settings or cached configuration pointing to GPT-3.5.

What You Can Do

• Double-check the Extension Settings: Ensure that the model is explicitly set to GPT-4 in the extension’s configuration. For example, if the configuration file includes a field like this:

  JSONCopied
  {
    "model": "gpt-4"
  }

  confirm that the value is correct and there are no overrides elsewhere.

• Review the Extension Documentation: Some VSCode plugins might note that GPT-4 is only available through certain settings or API endpoints. Verify that you’re following those recommendations.

• Confirm Your API Key and Endpoint: If the extension is using an API key that you provided, make sure it’s enabled for GPT-4. Although ChatGPT Plus provides GPT-4 access via the web interface, the API usage is governed by separate rate limits and configuration. Check if the extension’s API calls include the correct model name and headers.

• Update or Switch Extensions: It might be worth checking for an update to the extension or trying another one that explicitly supports GPT-4. Some plugins may still be primarily designed for GPT-3.5 even if they offer limited configuration for GPT-4.

In Summary

The behavior you’re seeing likely points to the extension falling back to GPT-3.5. This could be due to misconfigured settings, defaults within the extension, or limitations in support for GPT-4. Double-checking your configuration and ensuring your API key has the correct permissions should help resolve the issue.
