Short summary

Anthropic released Claude Sonnet 5 on June 30, claiming the most agentic Sonnet yet with capabilities near Opus 4.8 on autonomous web search and computer-use benchmarks. At $2/$10 per million tokens input/output (rising to $3/$15 after August 31), early adopters report improved autonomous task completion, self-verification without prompting, and fewer hallucinations. The shift reflects a broader trend: agent execution capabilities are migrating from flagship to mid-tier pricing tiers.
