Cost Tracking

Phoenix now allows you to track token-based costs for LLM runs automatically, calculating costs from token counts and model pricing data and rolling them up to trace and project levels for comprehensive analysis.New Features:
  • Automatic calculation of token-based costs using Phoenix’s built-in model pricing table.
  • Support for custom pricing configurations in Settings > Models when needed.
  • Token counts and model information are captured automatically when using OpenInference auto-instrumentation with OpenAI, Anthropic, and other supported SDKs.
  • For manual instrumentation, token count attributes can be included in spans to enable cost tracking.
  • OpenTelemetry users can leverage OpenInference semantic conventions to include token counts in LLM spans.
