What GPT-6 Astra is used for
Coding tools are chosen on workflow as much as on model quality. Ask how the tool gets context from your repository, whether it can run and test what it wrote, how it handles a large codebase, and where your code is sent when it runs. A tool that understands your project beats a stronger model with no context.
