About AI training and why it matters

AI training (also called data labeling or annotation) is the human work that powers modern machine learning: people review, classify, and improve examples that models learn from. This work is highly accessible, often remote, and a practical way to influence how AI understands code, documentation, and technical content.

• Contributors help improve model accuracy for tools, research, and educational products.
• Many assignments are part-time and let you set a schedule that fits your life.

The role — what you'll do

You will work as a Labeler/SME reviewing, categorizing, annotating, and evaluating technical programming content in one narrowly chosen specialty. Tasks include code labeling, evaluation/rating of responses, and writing or ranking model outputs (SFT-style). Your annotations will be used to build and refine training datasets for AI systems.

• Label and annotate code samples, documentation, and technical prompts.
• Evaluate and rate model responses and provide written feedback or SFT-style examples.
• Follow detailed guidelines to achieve high accuracy and consistency.
