Anthropic's cheaper, near-Opus everyday model
Added Jun 30, 2026
Claude Sonnet 5 is Anthropic's mid-tier model released June 30, 2026, replacing Sonnet 4.6 as the default model on Claude.ai's Free and Pro plans. It plans, uses tools like browsers and terminals, and runs autonomously, with performance approaching Claude Opus 4.8 on reasoning, tool use, coding, and knowledge work at a fraction of the cost. It also checks its own output without being explicitly asked to.
Why: Sonnet 5 is the practical default for most day-to-day work: it closes much of the gap to Opus-tier performance while staying meaningfully cheaper, and Anthropic made it the automatic replacement for Sonnet 4.6 across the free and Pro tiers.
