Benchmarks

Measure where models actually fail.

We design benchmark suites that go beyond academic leaderboard performance — targeting the vertical, expert-level tasks where frontier models still break down in practice.

Methodology

01

Expert-authored tasks

Every test case is written or validated by a domain specialist. We do not generate tasks from existing benchmarks or LLM outputs. The difficulty floor is set by what capable professionals actually find hard.

02

Real-world distribution

Tasks are drawn from genuine professional scenarios — not textbook problems or cleaned-up academic exercises. We preserve the ambiguity, noise, and context-switching that characterizes expert work in practice.

03

Tail-aware evaluation

We measure failure modes as carefully as successes. A model that scores 90% average but fails catastrophically on 10% of safety-critical tasks is not the same as one that scores 90% uniformly. We report both.

04

Contamination controls

Test sets are held out entirely from any training pipeline. We version-control task sets and rotate items over time to prevent leakage from model providers or public disclosures.

VLM Benchmark

Where vision-language models actually fail.

3 weeks

A high-difficulty evaluation suite testing vision-language models on complex, real-world scenarios that standard academic benchmarks consistently miss. Tasks span professional document analysis, multi-panel scientific reasoning, and visually ambiguous decision-making — designed so that current frontier models face genuine difficulty.

Evaluation dimensions

  • Multi-page document understanding
  • Scientific figure interpretation
  • Visual ambiguity and edge-case reasoning
  • Cross-modal consistency
  • Professional context grounding

Office Workflow Benchmark

The professional tasks models claim they can do.

3 weeks

Systematic evaluation of model performance across professional office workflows. Goes beyond single-turn QA to test multi-step reasoning across documents, formats, and tools — the kind of work a capable knowledge worker does every day, and the kind where current models consistently underperform against expectation.

Evaluation dimensions

  • Cross-format document synthesis
  • Multi-step task planning and execution
  • Spreadsheet and structured data reasoning
  • Email and communication drafting under constraints
  • Tool-use and workflow orchestration
