About two weeks ago, Bloomberg released a research paper detailing the development of Bloomberg GPT. This internal AI model can answer financial questions in the search function like "CEO of Silicon Valley Bank," asses the bullish or bearish sentiment of headlines, and even write headlines based on text. 

The tech behind Bloomberg GPT wasn't developed using supercomputers, nor is it using OpenAI's technology. Instead, Bloomberg used "freely available, off-the-shelf AI methods and apply them to its massive store of proprietary — if niche — data," CNBC said.
