  • The fsiovn FIM endpoint is only allowed to be used with the AI Autocomplete extension so all other uses are prohibited.

Compare with GitHub Copilot

GitHub Copilot remains a more full-featured product overall.

• Pros:

  1. Web support:

     GitHub Copilot still doesn't fully support VS Code for the Web (github.dev, vscode.dev).

     This extension works seamlessly in web environments, making it ideal for contributing to public repositories without a local setup.

  2. Lightweight:

     This extension is extremely small - around 40 KB, compared to 33 MB for GitHub Copilot + Copilot Chat.

  3. Focused on autocomplete:

     The extension is dedicated purely to autocomplete. Users who prefer external chat tools (Cline, KiloCode, ClaudeCode, Codex CLI, etc.) can combine them as they like.

  4. Privacy-friendly (BYOK):

     When users bring their own API key, the extension does not collect or store any code or usage data.

  5. No additional subscription needed:

     Users with a Cerebras Code Pro/Max or Gemini subscription don't need a GitHub Copilot plan.

  6. Better free tiers:

     Cerebras and Gemini both offer more generous free tiers compared to GitHub Copilot's current free tier.

• Cons:

  1. Copilot is generally more capable overall:

     While inline suggestions work similarly, GitHub Copilot tends to perform better in certain scenarios - especially with more advanced features like Next Edit, multi-file reasoning, and deep context understanding.

  2. No built-in chat:

     Unlike Copilot Chat, this extension intentionally does not include an integrated chat experience (though users can combine it with third-party tools if needed).

  3. Model quality depends on user's API key provider:

     Performance will vary depending on whether users choose Cerebras or Gemini and what tier they're on.

Overall, GitHub Copilot remains a more comprehensive solution, but this extension focuses on being lightweight, open-source, and flexible.
