Usage and pricing comparisons will determine whether Anthropic’s decision to make Claude Sonnet 5 introductory pricing permanent materially changes model selection for coding-agent workloads.

What is this?
Claude Sonnet 5 is an Anthropic model positioned for agentic work, including coding, browser, and terminal use, and made the default for Claude Free and Pro plans. Anthropic’s own announcement says its introductory API pricing is $2 per million input tokens and $10 per million output tokens through August 31, 2026, after which pricing rises to $3 and $15; several secondary snippets agree. The supplied evidence therefore does not establish that Anthropic made introductory pricing permanent and directly conflicts with the case’s stated event.
Why it matters to Scott
Scott already holds on AI Unit Economics and Model-Plus-Harness Benchmark Unit that model selection should be based on reliable cost per completed task rather than headline token prices. The supplied grounding contradicts the alleged permanent-price event, so this adds no actionable change beyond an already-held evaluation position.

The alleged permanent pricing change remains unsupported, while Anthropic’s published schedule explicitly says introductory pricing ends August 31. With no new evidence or engagement, the episode should close unless a later first-party announcement creates a new pricing delta.
