In the past, AI models like ChatGPT relied on vast teams of low-cost workers to identify basic facts.

Today, the demand for more sophisticated AI updates requires specialized human trainers, including historians and physicians.

Companies like Cohere, valued at over five billion dollars, are firms using specialized trainers to advance their AI models.

They partner with Invisible Tech, a startup employing thousands of trainers worldwide.

Invisible Tech, founded in 2015, caters to AI companies like AI21 and Microsoft to reduce errors known as hallucinations.

These efforts are essential for improving AI reliability and performance.
