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.
Open-source DynamoDB capacity visualization with Amazon Bedrock AI insights
Connect with an AWS access key and secret key, then browse and monitor the DynamoDB tables in your account.
Pick a table and date range to generate clear graphs of provisioned versus consumed capacity, so you can judge whether provisioning is right-sized.
A one-click AI panel uses Amazon Bedrock (Mistral 7B Instruct by default) to turn raw capacity data into written insights and provisioning recommendations.
Optionally save generated analyses and metrics to a DynamoDB table in your own account, then regenerate graphs later to compare trends over time.
