Sama review: the best managed route to synthetic AI training data
Answer in brief: Sama is our top pick for the synthesize route. When real data is too hard or too costly to get, its team defines what the data must cover, creates and augments prompts and responses, and checks the output against real data. People stay in the loop throughout. Sama also covers the label route with GenAI validation, preference ranking, captioning and computer-vision annotation. All its GenAI solutions are backed by SamaAssure.
Synthetic data, checked by people. SamaAssure is what Sama calls the industry's highest quality guarantee for generative AI.
