Copilot is an AI code assistant that offers autocomplete, chat, and commands. It has strong autocomplete performance using the OpenAI Codex model and offers in-IDE and mobile chat with GPT-4o. It also offers deep integration with the GitHub platform with Copilot Enterprise (for teams using GitHub Enterprise Cloud).
Unfortunately, Copilot is limited in how it uses code context. Copilot Enterprise can use code context from remote repositories, but it is limited to using code hosted in GitHub, specifically GitHub Enterprise Cloud (as Copilot Enterprise is not available for self-hosted GitHub). While Copilot offers the choice between multiple chat models, users are limited to a few models provided by GitHub directly. Enterprises can't host their own models, bring their own model keys, or connect to cloud providers like Amazon Bedrock and Azure OpenAI for a more private connection.
TL;DR: Copilot is a good choice for enterprises already using GitHub Enterprise Cloud and looking for a solution deeply embedded in the GitHub ecosystem. However, Cody is the better option for enterprises that want their AI solution to utilize context from a complete codebase spanning multiple code hosts or for enterprises that want to connect to self-hosted code hosts. Cody is also a better option for model flexibility: it allows teams to self-host models, bring their own model keys, or securely connect to LLMs via cloud provider services such as Amazon Bedrock.
