Google Antigravity is a buggy mess at the moment, but I believe it will eventually eat Cursor as well. The £20/mo tier currentluy has the highest usage limits on the market, including Google models and Sonnet and Opus 4.5.

It's not in Google's style, but they need a codex-like fine-tune. I don't think they have ever released fine-tunes like that though.

The model is very hard to work with as is.
