Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
Extract structured outputs such as company details, people and other entities for list building and data pipelines.
Train AI with domain experts and real-world data
Generate supervised fine-tuning prompts, reference answers, demonstrations and review rubrics with specialists matched to your subject area rather than generalist annotators.
Collect comparison data on accuracy, relevance, instruction following and domain quality so models can be tuned against ranked human preferences.
Capabilities Assessment responses against expert-defined criteria to surface errors, knowledge gaps and inconsistent behaviour, and run adversarial prompts to expose safety failures.
Capture real tasks in households, factories, warehouses, workshops, farms, labs and clinical settings to build training data for robotics and Physical AI.
