Claude Sonnet 4.6 (Anthropic)

Anthropic's Claude Sonnet 4.6 balances speed and intelligence for everyday work: drafting, analysis, research and code, at a lower price than Opus. It keeps up to 1M tokens in context, enough for long contracts or dozens of papers at once, and follows through on multi-step tasks more consistently than earlier Sonnet models. Turn on thinking for harder problems, attach images, text files or PDFs, or add web search.
