Rated as claude-sonnet-5-high (high effort); Claude Sonnet 4.6 as claude-sonnet-4-6. Some were rated at different settings; ratings on one arena share one scale, so the difference still reads directly. Text, WebDev, Vision, Search and Document ratings come from people voting between two anonymous answers; Text, Vision, Search and Document are style-controlled, as on arena.ai. Agent is Arena's separate score for real agent sessions, on its own scale. Data: Arena (arena.ai), CC BY 4.0.

Prompt cachingA prompt prefix you send again and again (system prompt, documents, tools) is cached, so later requests cost less and start faster.Supportedin place when tracking began (October 6, 2026)source
Batch APISend many requests as one job that runs in the background, usually finished within 24 hours, at a lower price than live requests.Supportedin place when tracking began (October 6, 2026)source
