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.
Source-backed AI research over SEC filings for public companies
Ask plain-English questions about 10-Ks, 10-Qs and 8-Ks. The assistant retrieves the relevant filing excerpts and streams an answer with citations you can open to inspect the source text.
Deep Mode extracts entities and relationships from filings and maps companies, people, products, ownership, strategy and risk into a dual-view network where every node links back to evidence.
Search extracted connections to answer who is tied to whom and how, then follow dated events across filing periods to see how leadership, strategy and risks evolved.
Add companies to a watchlist and get AI-summarized notifications when a new 8-K, 10-Q or Form 4 lands, with insider transactions organized for quick review.
