## The use case: how Dropbox deploys Braintrust

Dropbox uses Braintrust to evaluate the AI features of its Dash product. It runs a multi-tier pipeline of pre-merge smoke tests, a full post-merge suite, and online LLM-as-a-judge scoring of sampled production queries, and feeds production traces back into new test sets.

> Evals are how Dropbox applies this testing rigor to its AI, and with Braintrust they've built a structured, multi-tier testing pipeline:

- **150**: “Pre-merge smoke tests (150 tests).”

> We can run hundreds to thousands of experiments with Braintrust.
