I got the Max subscription and have been using Opus 4.6 since, the model is way above pretty much everything else I've tried for dev work and while I'd love for Anthropic to let me (easily) work on making a hostable server-side solution for parallel tasks without having to go the API key route and not have to pay per token, I will say that the Claude Code desktop app (more convenient than the TUI one) gets me most of the way there too.
