I'm interested in how it feels to use: whether there is any context leaking, as you mentioned, if it introduces latency, and whether there are any pricing implications? I know they weighed a variety of factors, including the smaller models, but cost had to be a big concern, too... I feel like Google is the only provider giving away so much AI inference for free.

This will further blur the picture about when and how consumers / employees are supposed to pay for AI services. For example, they showed consumer rather than coding tasks, but could you select five files and ask Siri to write a Python script or a small app? Will enterprises just disable Siri AI functionality, or will they be able to route it through their own AI auditing and providers?
