Claude Sonnet 5 Offers 60% Discount Over Opus, But Only Temporarily
Anthropic launched Claude Sonnet 5 on June 30, 2026, with intro pricing at $2 input and $10 output per million tokens through August 31, a 60% discount versus Opus 4.8. After the intro, pricing rises to $3/$15, still 40% cheaper than Opus. The model is broadly available across Claude tiers and GitHub Copilot, making it the default for many coding agents.

The discount is real and significant, but developers should treat Sonnet 5 as a cost-effective first pass, not a universal Opus replacement for high-stakes tasks.
