Precision Data for Giant AI Leaps
While we build data services, we don't train models directly. Instead, AI labs use our platform for their training pipelines. We don't plan to release any consumer-facing products in the foreseeable future. Our current focus is enabling high-quality AI development, but our long-term goal is to support the advancement of AI across all valuable applications in the economy.
Models are provided with precisely labeled datasets for tasks such as RLHF tuning, object detection, or speech recognition. Their performance is evaluated based on how successfully they utilize these datasets. These evaluations serve as quality signals during training, teaching models how to understand and process real-world data effectively.
We are a data platform that builds high-quality annotation services and sells them to the leading AI labs. Our platform provides data annotation, curation, and model evaluation for training LLMs and computer vision models.
