Not everyone is convinced. Some analysts say the update is mostly about catching up with rivals rather than moving the field forward. Others point to small but useful changes that the headlines missed.
We will update this story as more independent testing is published. If you have used the feature and want to share what you found, write to the editorial team.
The bigger picture
If you use these tools at work, ask your administrator whether the new feature is turned on, and what the company policy says about using it with customer data.
- Independent tests are still limited
- API access at a separate price
- No change to default privacy settings
- Rolling out region by region
What to watch next
The announcement came with a short blog post, a technical document and a handful of demos. As usual, the demos show the best case. We read the documentation to see what the product does on an ordinary day.
We are seeing steady progress, not a leap. That is still useful for the people who rely on these tools every day.
An independent researcher
Independent researchers were quick to test the claims. Early results broadly match what the company said, with the usual caveat: benchmarks measure narrow skills, and real work is messier than a test set.

What critics say
Privacy groups asked how the new data will be stored and for how long. The company says customer data is not used for training by default on business plans. Consumer plans have a setting that you should check.
Developers get the same capability through the API, with a separate price list. Several startups said they will update their products within days, which is usually how new features reach most people.
