· Generative AI Evaluation
Measure what models actually do.
Seuil independently evaluates generative pipelines — faithfulness, accuracy, and operational risk — so leadership can decide at the threshold, not from a demo.

Solutions
Judgment, written down.
Seuil is an independent consultancy. We evaluate generative systems — LLMs, RAG pipelines, and agents — so a production decision can be owned: ship, hold, or roll back, on evidence rather than a demo.
- 01
Evaluation Strategy
Failure modes, task taxonomies, rubrics, and the written line between ship, hold, and rollback.
- 02
Golden Datasets
Provenance-tracked test cases from real production distribution — including the rare and the high-stakes.
- 03
Evaluation Harnesses
Repeatable scoring in CI/CD. Judges calibrated. Gates that fire before the answer leaves the building.
- 04
Human Evaluation
Calibrated SME review where automation is not enough — with agreement measured, not assumed.
- 05
Agent Evaluation
Process quality — tool calls, recovery, hand-offs — not only the final answer.
- 06
Continuous Evaluation
A living scorecard. The same dimensions, re-run as models, prompts, and traffic drift.
- 07
Risk & Compliance
Red-teaming, policy adherence, fairness, and audit-ready evidence for the committee that asks.

Company
Independent of the model. Accountable to the threshold.
Seuil is a consulting practice for organisations that must know whether a generative system is ready — not impressive. We do not sell a model, and we do not sit inside the vendor’s narrative.
Athena is the figure for a reason. Wisdom here is not fluency. It is measure: what can be shown, what fails, and where the line is drawn before the answer leaves the building.

Get Started
When a model is ready is not a feeling.
Write with a system in mind. We will tell you whether it can be evaluated, and what the first ledger would contain.
