Real-world simulations for long-horizon AI agents.

ARIMLABS builds production-fidelity simulations where AI agents run multi-hour tasks, and the benchmarks that measure what frontier models actually do.

RLVR Environments

4 areas

Carefully calibrated training environments for the agents of tomorrow.

  • Cyber — offense and defense environments
  • SRE — incident response simulations
  • Compilation — build, toolchain, and dependency repair
  • STEM — verifiable reasoning and problem solving

Benchmarks

2 areas

We measure what frontier models can actually achieve on the bleeding edge of long-horizon, domain-specific tasks across cybersecurity, SRE, terminal use, STEM, and more.

  • Isolated capabilities
    CTF-style challenges, vulnerability identification, exploit development, code audit — single-step or short-task tests that isolate one skill.
  • Long-horizon environments
    Multi-hour red-team operations, defensive triage under active adversary, persistent offensive ops — full kill chains that unfold over hours or days.

LLM Safety Benchmarking

3 areas

Testing for containment failure, deception, and hidden capability in frontier models.

  • Containment
  • Deception and sandbagging
  • Capability elicitation
