via “cost estimation and token counting across providers”
Test your prompts, agents, and RAGs. Red teaming/pentesting/vulnerability scanning for AI. Compare performance of GPT, Claude, Gemini, Llama, and more. Simple declarative configs with command line and CI/CD integration. Used by OpenAI and Anthropic.
Unique: Aggregates token counts from provider responses and applies provider-specific pricing formulas (including dynamic pricing like Claude's cache tokens) to estimate costs before or after evaluation. Enables cost-aware test planning and budget management.
vs others: More accurate than manual cost calculation because it tracks actual token usage, and more actionable than post-hoc billing because cost estimates enable planning before expensive evaluation runs.
