Having access to dozens of models through a single API key, tracking cost of each request, being able to run the same request on different models and comparing their results next to each other, separating usages through different API keys, adding your own presets, setting your routing rules...
And once you start using an account with multiple users, it's even more useful to have all those features!
Not relying on a subscription and having the right to do exactly what you want with your API key (using it with any tool/harness...) is also a big plus to me.
Because GH is accessing the API behind the scenes, you should face less degradation when using Sonnet/Opus models compared to a Claude subscription.
Keep a ChatGPT $20 subscription alongside for back-and-forth conversations and you'll get great bang for buck.
Any insights / suggestions / best practices?
OpenCode picked up my CLAUDE.md files and skills straight away, and I got similar performance to Opus 4.6.
Also ditching Claude Code is mistake. It is quite capable model, and still great value. I would keep it, even if it's just for code reviews and planning. Anthropic allows pro plans use in Zed.
1. What do you use the hooks for?
2. Do you use an editor alongside the CLI to review code or only examine the diffs?
