Toptal vs BairesDev: overview
Toptal
Toptal has run its remote freelance network since 2010, and its buying model is the most flexible on the hours side. You can book a machine learning, NLP or generative AI specialist for a few hours a week or full-time, billed hourly or weekly, and each new engagement starts with a no-risk trial. Toptal says fewer than 3% of applicants pass a screen that ends with interviews by senior engineers and a test project. What you give up is a stable employee: freelancers choose their clients, and Toptal publishes no rate card.
BairesDev
BairesDev was founded in Buenos Aires in 2009, is headquartered in San Francisco and employs several thousand engineers across Latin America. Buyers can choose staff augmentation, dedicated teams or project delivery, and the AI practice covers ML, data engineering and generative AI. It is a practical choice when one contract needs to cover AI engineers and the software developers around them. As a generalist, though, its AI depth varies by engineer, and rates are not published.
