Copilot isn’t really a competing product to Claude - in fact I use Claude through copilot.
I have found in general that for the type of work I do (senior to staff level engineering, 90-10 research to programming) that Claude Opus is the only model really worth my time - but I just really like the Copilot CLI tooling.
I do use LLMs to learn about new subjects but we already only bill 10% for "coding" and that's inflating it to cover other parts.
I can't imagine that slopping it up would be a great decision. Having alien code that no one ever understood between a bug report and a solution. Anthropic isn't going to give us money for our lost contracts, is it?
