01 / 04 · Frontier evals
Evals that predict production.
Custom benchmarks built from your real use cases — not leaderboard trivia. Capability elicitation, LLM-as-judge calibrated against expert humans, contamination checks, and a harness you keep.
- Capability maps per checkpoint
- Rubrics & judge calibration
- Contamination & regression checks
02 / 04 · Red-teaming
We break it before your users do.
Adversarial testing by people who live inside these models. Jailbreak discovery, prompt-injection audits for agents, refusal calibration and reward-hacking hunts — every finding reproducible.
- Jailbreak & policy bypass
- Prompt injection · tool abuse
- Over- & under-refusal
03 / 04 · Post-training data
Data that moves the loss curve.
Expert-written SFT demonstrations, preference pairs for RLHF and DPO, and reasoning traces — designed against the failures we found, and measured on the evals that matter.
- SFT demonstrations
- RLHF · DPO preference pairs
- Reasoning traces & rubrics
04 / 04 · RL environments
Worlds for agents to learn in.
Verifiable tasks with graders that can't be gamed — tool-use, browser and workflow sandboxes where agents roll out, fail, and get better. Built for long-horizon reliability.
- Verifiable tasks & graders
- Tool-use & computer-use sandboxes
- Long-horizon trajectories
