There was a really cool blueprint released which uses this. Basically, it asks for your calendar entries for the day, include those and weather info etc. in a prompt to e.g. chatGPT, asking for a summary, and then sends this reply as a notification to your phone.

Scripts can also return information now, allowing for cleaner scripts and automations theough Separation of Concern. For example; I sometimes want to turn on lights to a set brightness depending on the time of day, and now I can make a script to calculate the correct level that I then use in all automations. This eliminates the slight delay you get with e.g. f.lux or Adaptive Lighting.
