Sourcebae

Sourcebae is a specialized online platform that connects pre-vetted domain experts with leading artificial intelligence companies for critical AI training tasks. The platform focuses on providing high-quality human expertise for data labeling, reinforcement learning from human feedback (RLHF), model evaluation, and red teaming. It functions as a two-sided marketplace: on one side, AI firms such as Google, Meta, Anthropic, and over 200 other companies seek skilled professionals to annotate data, refine model outputs, and stress-test AI systems for safety and reliability. On the other side, domain experts—ranging from linguists and medical professionals to software engineers and creative writers—register to offer their specialized knowledge. The core process begins when an expert creates a profile on Sourcebae, specifying their domain expertise, qualifications, and availability. The platform then uses an AI-driven verification system to assess the expert’s skills and match them with suitable projects. This matching mechanism ensures that tasks are assigned to individuals who possess the precise background required, such as a radiologist for medical image labeling or a native speaker for dialect-specific language model training. Once matched, experts can choose from a variety of project types: annotation (e.g., bounding boxes for computer vision, text classification), RLHF (ranking model responses to align with human preferences), model evaluation (testing AI outputs for correctness, bias, or safety), and red teaming (deliberately probing models for vulnerabilities or harmful behaviors). Work is fully remote and asynchronous, allowing experts to operate on their own schedule. Payment is processed weekly, with no fees or hidden costs, and rates typically range from $15 to $
