Notes
- All prices confirmed from official sources on July 19, 2026. Verify before citing.
- Arena Elo scores are dynamic; this snapshot captures one point in time.
- SWE-bench Verified, AIME 2025, GPQA Diamond, and MMLU-Pro scores require dedicated searches and may not be available on the same day.
- Anthropic's new tokenizer (Opus 4.8+, Sonnet 5+) generates ~30% more tokens for the same text — this should be factored into any cost-per-task calculation.
- DeepSeek V4 Flash cache hit pricing ($0.0028/MTok) makes it the overwhelming value leader for repeated-context workloads.
- Google Gemini pricing was unavailable at snapshot time (timeout). Refer to https://ai.google.dev/pricing for current rates.
