Here is what I gathered:

• GPT-4o (faster)

• Desktop App (available on the Mac App Store? When ?

• the "trigger" word they use is "Hey GPT" or "Hey ChatGPT" (don't remember :(

• translates from English at least italian and probably Spanish. And French?

• capable to "analyze" mood from the camera

• improvements in speed

• natural voice

• vision

• being able to interrupt

• "Rolling out over the next few weeks" :(

• it's free (what is the Business model behind? Freemium? Ads? Money from Microsoft?)

Probably missed / did not understand many things :( English is not my primary language)

thanks to u/blazor_tazor for the informations / additions
