Question

A platform engineer is documenting how a single Copilot code completion travels from the model back to the developer's editor. They want to explain, at a high level, what happens to a candidate suggestion inside GitHub's Copilot proxy service before it is returned to the client. Which statement most accurately describes the proxy's post-processing responsibility in the code-suggestion lifecycle?

Accepted Answer

The proxy applies filters such as the optional public-code (duplication) match check and toxicity/security screening, and may block or drop a candidate before it reaches the editor.

Answer

The proxy stores every generated suggestion in a per-user history database so the same prompt always returns an identical cached result.

Answer

The proxy retrains the underlying model on each accepted suggestion so future completions improve for that specific developer.

Answer

The proxy performs no processing on generated text; all filtering happens entirely inside the local IDE extension after the suggestion arrives.
