Price receipt
We read Anthropic's own pricing page on Aug 13, 2026 and found Claude Sonnet 5 listed with a price on the same row — that read is where the number above comes from. We keep the page text we read; its content hash is 89a12b8bd5.
Overview
Anthropic's most agentic Sonnet yet — performance approaching Opus 4.8 at a fraction of the price, strong on reasoning, tool use, coding and autonomous agent workloads. $2/$10 per 1M tokens — first announced as launch pricing, now Anthropic's standard price; the increase once scheduled for Sep 1 2026 will not happen.
