Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language
Feed KaneAI text, tickets, docs, diffs, images or media and it drafts scenarios and test cases automatically.
Written steps describe intent rather than selectors, so the tests remain readable to non-engineers.
Authored tests convert into runnable automation for web and mobile, executed at scale on the cloud grid.
Intent-based steps and AI-based error classification reduce flakiness and false failures as the UI evolves.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
