Anthropic's Claude API pricing page, read September 25, 2026, lists Claude Sonnet 5 at $2 input / $0.20 cache hit / $10 output per million tokens; five-minute and one-hour cache writes are $2.50 and $4, and Batch API input and output are $1 and $5. A footnote on the $2/$10 row states that this pricing, announced at launch as introductory pricing through August 31, 2026, is now the standard price, and that the previously scheduled increase to $3/$15 on September 1, 2026 will not occur. Anthropic's launch post carries an August 10, 2026 edit saying the introductory pricing is now permanent (https://www.anthropic.com/news/claude-sonnet-5). The rate has applied since the June 30, 2026 launch. 1M-token context window.
