What Invisible supplies to AI labs

Proof point: Cohere

Invisible's case study says it sourced PhD-level experts in STEM, math, SQL, HR, retail and aviation to blind-annotate evaluations of Cohere's Command A. It also says it helped Cohere expand into 10 languages. Invisible reports a 51.7% average win rate for Command A in that work. These are Invisible's reported figures.
