I wouldn't use Claude API Key pricing, but I also wouldn't get a Claude Max sub unless it was the only AI tool I used.

Antigravity / Google AI Pro is much better value, been using it as my primary IDE assistant for a couple months and have yet to hit a quota limit on my $16/mo sub (annual pricing) which also includes a tonne of other AI perks inc. Nano Banana, TTS, NotebookLM, storage, etc.

No need to use Anthropic's premium models for tool calling when Gemini/MiniMax are better value models that still perform well.

I still have a Claude Pro plan, but I use it much less than Antigravity and thanks to Anthropic axing their sub usage, I no longer use it outside of CC.

Counterpoint: on the $20 monthly account I would hit my 5 hour limits within an hour on antigravity. I end up spending half my time managing my context and keeping conversations short.
