Sovrano AI

Sovrano AI is a European platform dedicated to enhancing the development of artificial intelligence through expert human evaluation. It connects skilled individuals with AI companies to assess and improve AI models, ensuring their outputs are reliable and aligned with human values. The platform offers remote, flexible, and paid opportunities for evaluators across various domains, including finance, law, STEM, marketing, and general business. The process begins with users creating a free account, which requires no university email and is entirely free of charge. After registration, candidates undergo a short skills assessment tailored to their expertise, covering domain knowledge and evaluation abilities. This assessment helps match them to suitable projects from top AI companies across Europe. Once matched, evaluators can start working on tasks such as Reinforcement Learning from Human Feedback (RLHF), data annotation, red-teaming, safety evaluations, response writing, and rating and scoring. These tasks involve ranking AI-generated responses, labeling data, identifying vulnerabilities, crafting ideal responses, and scoring AI outputs based on predefined criteria. Sovrano AI emphasizes the importance of genuine human judgment in the evaluation process. The use of AI tools to perform evaluations is strictly prohibited, as it undermines the purpose of human assessment and can degrade model quality. Evaluators are allowed to use tools for grammar and spelling correction but must rely on their own reasoning and analysis for the evaluation tasks. The platform also offers a referral program, allowing users to refer researchers, labs, or students to join Sovrano AI. Referrers earn a flat €20 for every intern hire or 20% of everything their contractor referrals make, capped at four times the referral's first accepted hourly rate. For students and scholars, Sovrano AI provides structured internships that combine AI education with hands-on evaluation work. These internships are designed to fit various university formats, including part-time semesters, for-credit integrations, and summer intensives. Participants receive mentorship, structured assessments, and certifications upon completion, enhancing their employability in an AI-driven job market. Payments are processed through Deel, a global payroll platform. Evaluators set up their Deel accounts during onboarding, providing personal details, tax information, and bank account or withdrawal methods. Payments are processed in euros, with Deel handling currency conversions if necessary. The earnings dashboard allows users to track their payments, filter earnings by contract or time period, and download payment reports for tax purposes. Sovrano AI's mission is to build the infrastructure for trustworthy AI by leveraging human expertise to validate and improve AI models. By connecting evaluators with AI companies, the platform ensures that AI development is grounded in human consensus, learning, and scalability.
