What is Sourcegraph Cody and how does it handle large codebases?

Sourcegraph Cody is an AI coding assistant specifically designed for large, complex codebases using Sourcegraph's code intelligence platform for context. Unlike tools that limit context to open files, Cody can search across your entire codebase using Sourcegraph's code graph, making it particularly valuable for understanding large legacy systems or enterprise monorepos where the relevant code could be anywhere.
