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.
Automated AI-answer verification via one API call
A single balanced metric that combines completeness, correctness and contradiction checks, so an answer is graded on more than surface similarity.
Call the evaluation endpoint from any language or workflow and incorporate answer verification into development and CI/CD processes.
Import the evalmyai client, pass expected/actual answer pairs and receive a structured evaluation result directly inside your Python code.
Out-of-the-box validation plus tunable semantic-scoring settings let testers adjust strictness based on their risk profile.
