Why we don't have claude haiku 4.5 model in google antigravity yet?

it is kinda good model when used as explorer or in ask question setting, so i was wondering why google has not added it?

Hello @duff-nova, welcome to AI Forum!

Thanks for the feedback! We are aware of the demand for the newest Claude models.

Currently, our priority is optimizing the Gemini lineup (Pro and Flash) to handle the heavy lifting of the agentic workflow. We don’t have a specific timeline for the integration of external models like Claude Haiku 4.5 yet.
