Can AI Agents Adapt When the World Changes?

AI agents often struggle when environments change mid-task, risking outdated decisions, lost work, and unsafe actions. This research proposes the State-Shift Evaluation Protocol (SSEP) to evaluate how reliably agents detect, adapt to, and safely handle unexpected changes.

WHAT WE DO

Three ways to get capable-agent data.

Custom RL Environments

Purpose-built, containerized environments for coding agents, computer-use agents and other systems that learn through verifiable interaction.

Capabilities: Task design, environment engineering, automated graders, reference solutions, reward signals, adversarial validation and model-run analysis.

Explore RL Environments

Off-the-Shelf Datasets

Private, unpublished coding-agent tasks available for controlled sampling, direct acquisition, and exclusive or non-exclusive licensing.

Capabilities: Terminal workflows, DevOps, system administration, debugging, repository-level engineering and long-horizon agent tasks.

View Available Datasets

Benchmarks & Research

Independent benchmarks and evaluation systems designed to measure whether AI agents can complete difficult real-world work reliably.

Capabilities: Reproducible execution, task validation, repeated model trials, trajectory analysis and evidence-based reporting.
