Datasets as the source of truth
Braintrust organizes test cases into datasets that can be versioned and reused across experiments.
SERVICES / EVALUATION PLATFORMS
Get real value from Braintrust experiments.
Independent planning and implementation for teams considering or using Braintrust: reviewed datasets, trustworthy scorers and experiments that drive release decisions.
Where Braintrust fits
Experiments and comparisons
Each change can be run as an experiment and compared with previous ones, case by case.
Scorers and human review
Automated scorers, including its open-source autoevals library, sit alongside human review of individual results.
Common gaps we fix
Datasets that don't reflect reality
Test sets built from a handful of developer examples miss the journeys and edge cases real users bring.
Scorers nobody trusts
Model-graded scores that haven't been checked against experts lead to arguments rather than decisions.
Experiments without a decision rule
Lots of comparisons, but no agreed threshold for what counts as better enough to ship.
How we help
Curate representative datasets
Combine approved interactions, expert scenarios and reviewed synthetic cases, tagged by workflow, difficulty and risk.
Design and calibrate scorers
Code scorers for objective checks, rubric-based judges for quality, both validated against reviewer labels.
Set decision rules
Agree baselines, critical-failure rules and thresholds so experiment results translate into clear go or no-go calls.
Make it routine
Release integration
Run agreed experiments on relevant changes in your development workflow, with critical checks as gates.
Promote failures into tests
Confirmed failures from reviews become dataset cases, so fixed problems stay fixed.
Team enablement
We train engineers and reviewers to add cases, read results and maintain scorers after handover.
From scope to handover
Start with your inputs
Representative tasks, expected outcomes, platform access and a domain reviewer.
Keep reusable assets
Versioned datasets, scorer code and prompts, a baseline experiment, prioritized findings and a documented rerun process.
Support after handover
We can retest fixes, extend coverage to new Braintrust workflows or move to recurring Managed Evaluations as your agent changes. Platform usage and licenses stay in your account.
Make your next decision with evidence.
Start with one workflow, clear success criteria, and an evaluation plan your team can use.
