Evaluation criteria

From eval tests

We validate VTT structure, translation faithfulness, and language code integrity, plus performance and budget targets.

English Translation
"Together we can reach more"
EN / ENG • Confidence 100%
Contextual Localization
Efficacy checks
  • Translated VTT starts with WEBVTT and keeps timestamps.
  • Cue count matches the original and translation differs.
  • Faithfulness scoring against the original transcript.
  • Language codes match ISO 639-1/3 and are consistent.
  • Response preserves asset ID and language fields.
Efficiency targets
  • Latency: scores are normalized between 0 and 1. Under 8s earns 1.0; past 15s trends toward 0.
  • Token usage: scores are normalized between 0 and 1. Under 2,500 tokens earns 1.0; higher usage reduces the score.
Expense guardrails
  • Estimated cost under $0.012 per request for full score.
  • Usage data must include total tokens for cost analysis.
