RL Data Infrastructure
We build high-quality reinforcement learning datasets — from code reasoning and competitive programming to multimodal tasks. Every sample is verifiable, every reward signal is grounded.
End-to-end RL data pipelines — from problem curation to verified reward signals.
Competitive programming problems with verified test cases, automated judging, and outcome-based reward signals. Built on our own online judge infrastructure.
Chain-of-thought datasets for mathematical reasoning, proof generation, and logical deduction. Ground-truth verifiable outputs for reliable reward modeling.
Vision-language pairs, spatial reasoning tasks, and embodied action sequences. Expanding into robotics and real-world interaction data.
Human preference rankings, comparison pairs, and reward model training sets. Scalable annotation pipelines with expert labelers.
Currently focused on code & reasoning. Expanding across every modality.
Whether you need 10K samples or 10M, we'll scope a pipeline that fits your model's appetite.
