I'm using it via Copilot, now considering to also try Open Code (with Copilot license). I don't know if it's as good as Claude Code, but it's pretty good. You get 100 Sonnet requests or 33 Opus request in the subscription per month ($20 business plan) + some less powerful models have no limits (i.e. GPT 4.1), while extra Sonnet request is $0.04 and Opus $0.12, so another $20 buys 250 Sonnet requests + 83 Opus requests. This works for me better since I do not code all day, every single day. Also a request is a request, so it does not matter if it's just a plain edit task or an agent request, it costs the same.

Btw. I trust Microsoft / GitHub to not train on my data more (with the Business license) than I would trust Antrophic.
