From tasks
to training data
Every step matters

Data quality starts with a verifiable process.

239.AI explores coding tasks, terminal trajectories, multimodal samples, and synthetic data, including frontier research and open-source projects. Technical insights and method analysis help model and agent teams assess data for their training goals.

Technical insight.
Real data needs.

A dataset's value depends on how its content fits the training goal. Task coverage, sample structure, difficulty, and correctness are key to assessing suitability.

Discuss dataset purchases or request custom data. Start with your training use case and the samples you need, then work through data scope, volume, budget, and delivery timing.

Explore dataset content, quality, and limitations in the articles, then discuss the data you need. Purchase terms, delivery arrangements, and pricing are agreed for each engagement.
