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.
See and control your AI spend across every provider from one dashboard
Track token usage and spend across OpenAI, Google AI, Azure, Bedrock, and other services in one view, so you can see which provider is driving costs.
Project your bill based on current usage patterns so budgets stay under control and end-of-month surprises are avoided.
Get notified when usage jumps, catching retries, broken prompts, or runaway jobs before they compound into large bills.
Recommendations generated from usage and billing signals suggest cheaper model substitutions, idle GPU shutdowns, and retry or error fixes.
