Question

A developer at a fintech company notices that when they ask GitHub Copilot's code completion to generate a function similar to one they wrote in a file they edited an hour ago (now closed), Copilot does not seem to 'remember' that earlier code and produces a structurally different result. They ask you why Copilot cannot recall their previous work session. Which explanation best describes this limitation of how Copilot completions work?

Accepted Answer

Copilot completions are stateless: each suggestion is generated from a prompt assembled at request time from currently available context, and the model retains no memory of prior sessions or closed files.

Answer

Copilot stores all prior prompts in a per-user vector database, but fintech content-exclusion rules automatically purge them after one hour.

Answer

Copilot fine-tunes a personalized model from your edits, but the retraining only occurs overnight, so earlier code is not yet reflected.

Answer

Copilot does remember prior sessions, but the proxy's toxicity filter blocked the earlier context from being reused in the new suggestion.
