Welcome to the 221st issue!

What will be the impact of GPT-4o on testing?

Thanks to its new ability to interpret more input sources, such as audio, image or video, it immediately got the attention of the testing community.

In one example, someone tried to automate web UI tests from a single screenshot.

The result? It's a significant improvement in assisting testing but it's not taking it over... yet.

However, keep in mind that we might also face other problems because, apparently, GPT-4o's Safety Tests Started Failing, as Jason Arbon points out.

So, whatever the future brings... happy testing! 🙂
