The environments frontier AI trains on, and the agents that do the recurring work
Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
Evaluation, data and post-training infrastructure for AI in game development
Benchmark suites such as GameEngineBench score how well AI models handle real game-engineering tasks, producing a leaderboard rather than anecdotal demos.
The team measures specific failure modes of models in game development contexts and turns those findings into published methodology and papers.
Contractor-sourced Unreal Engine 5 data and reinforcement-learning environments are produced for labs that need high-quality training material.
Rather than only publishing static datasets, Nitrode builds interactive environments where models can learn to create games by acting in them.
