AWS Lambda Deployment

Deploy Fair Forge generators, runners, and metrics as AWS Lambda functions for serverless execution.

Available Lambda Functions

Function	Purpose	Endpoint
BestOf	Tournament-style AI assistant comparison	`POST /run`
Generators	Generate test datasets from context	`POST /run`
Runners	Execute tests against AI systems	`POST /run`

BestOf Metric Lambda

Run tournament-style comparisons between multiple AI assistants to determine which performs best.

How It Works

Submit datasets from multiple assistants (same questions, different responses)
The LLM judge evaluates head-to-head matchups
Winners advance through elimination rounds
Returns the tournament winner with detailed contest results
