Custom Benchmarks
Purpose‑built tests that stay ahead of frontier models—and tell you how close models are to practical value.
LLM Leaderboards are Saturated
Sepal AI crafts use case specific item banks large enough and hard enough to give researchers signal into model improvements.
Purpose build for precision
We workshop goals, failure modes, and real‑world scenarios with your Safety or MTS team.
Partial test sets ship every two weeks; full suite in 4‑8 weeks.
Iterate on rubric and difficulty until it measures what matters.
Crafted by elite domain experts, ready to drop straight into your eval pipeline.
Quarterly refreshes guarantee lasting headroom so the test keeps separating good models from frontier breakthroughs.
Generate custom test suites for varied mediums like computer use and image processing.
Stress‑test guardrails, spot catastrophic failure paths, and generate audit‑ready evidence before launch.
Pinpoint missing skills, compare training runs, and justify compute spend with hard numbers.
Trusted by Frontier Labs
OpenAI, Anthropic, and other pioneers rely on Sepal to deliver human evaluation signal at the speed of modern release cycles.
