what is an seu?

Standard Evaluation Unit

SEU is our universal measure of platform usage. Each experiment evaluation consumes SEUs based on complexity. Most standard evaluation runs use 1-3 SEUs, making costs predictable.

Managed LLM

We handle all LLM API calls. SEU pricing covers model cost + platform.

  • No API key management
  • Included SEUs per tier
  • Overage at tier rates

BYOK (Bring Your Own Key)

Use your API keys. Pay LLM providers directly. Platform fee only.

  • Platform fee: $0.015/SEU
  • Use existing API contracts
  • Full control over LLM spend
