We believe in making our tools available gradually, which allows us to make improvements and refine risk mitigations over time while also preparing everyone for more powerful systems in the future. This strategy becomes even more important with advanced models involving voice and vision.
My issue isn't fully with them rolling out slowly, my issue is never knowing when you will get the feature or rather not being told when you do get it. I'm fine with "sometime in the next X days/months you will get feature Y", my issue is the only way to see if you got feature Y is to check back daily.
