Turley, a witness for the government, testified earlier in the day that Google shot down a bid by OpenAI to use its search technology within ChatGPT. OpenAI had reached out to Google after experiencing issues with its own search provider, Turley said, without naming the provider. ChatGPT uses technology from Microsoft's search engine, Bing.

"We believe having multiple partners, and in particular Google's API, would enable us to provide a better product to users," OpenAI told Google, according to an email shown at trial.

OpenAI first reached out in July, and Google declined the request in August, saying it would involve too many competitors, according to the email.

"We have no partnership with Google today," Turley said.

The DOJ's proposal to make Google share search data with competitors as one means of restoring competition would help accelerate efforts to improve ChatGPT, Turley said.

OpenAI competes with Google, so obviously the government invited them to testify about how Google is a big bully that has no competition.

maybe one line of defense is that Chrome is good for society, but no one wants to buy and support it..
