ANTHROPIC

Computer Code ProgrammingPrompt Response Writing SFT
This AI training project with Anthropic involves evaluating and improving model-generated responses to a wide range of prompts, focusing on accuracy, clarity, relevance, and safety. The work includes reviewing outputs, identifying issues such as factual errors, bias, or harmful content, and providing structured feedback or corrections to help refine model performance. It requires strong critical thinking, attention to detail, and a solid understanding of language and context, as well as the ability to follow evaluation guidelines consistently to support the development of more reliable and aligned AI systems.

VIDEO ANNOTATOR

VideoSegmentation
This video labeling project focuses on precise **segmentation annotation**, where objects in each frame are labeled at the pixel level to create high-quality training data for computer vision models. Annotators carefully outline and track objects across video sequences, ensuring consistency despite challenges like motion, occlusion, and lighting changes. The goal is to produce accurate segmentation masks that allow models to recognize, differentiate, and follow objects over time, supporting applications such as autonomous systems, surveillance, medical imaging, and advanced video analytics.
