It's hard to tell exactly without knowing what's going on under the hood, but what has significantly got better in recent months for me is:
- Individualized predictions (it clearly picks up things I often write, including slang and abbreviations)
- Multi-words predictions ("What time" completed by "is it" instead of "is", "it")
- Context dependent predictions: predicts email addresses when I'm in the "To" field of an email, predicts an URL when I'm in the browser's omnibox, etc.
- Multi language support (I can mix English and French in my texts... Happens all the time)
Yes, but that’s not much of a feature. You don’t have to detect anything, you can just use a different prediction model for each context, and train each separately.
