How were these rankings determined?
Rankings combine (1) benchmark scores weighted by what matters for translation / multilingual — for example coding benchmarks dominate for coding, long-context retrieval dominates for RAG and long documents, (2) cost at a typical production volume, (3) speed and latency tier, (4) ergonomics like prompt caching and structured output, (5) recency of release, and (6) a curated editorial boost for provider-specific strengths that generic benchmarks miss (e.g. Gemini's advantage on maps and geospatial tasks).
