AI Evaluation Platforms: When to Buy vs Build
Eval platforms (Braintrust, LangSmith, Weights & Biases) accelerate teams. The buy-vs-build call depends on team size, use cases, and customization needs.
Creators · Tools Literacy · ~24 min read
The premise
AI evaluation infrastructure is a differentiator; platforms accelerate teams but lock in some choices.
What AI does well here
- Evaluate platforms on coverage of your eval needs (offline eval, online monitoring, regression testing)
- Assess integration cost into your existing infra
- Plan for the platform's role in your team workflow (who uses it, when)
- Maintain ability to migrate (avoid total platform lock-in)
What AI cannot do
- Get evaluation right without organizational discipline regardless of platform
- Substitute platforms for actual eval design thinking
- Eliminate the maintenance burden
