Purpose
Claude models change quickly. Launch pages, pricing tables, system-prompt notes, release notes, and deprecation pages answer different questions. Claude Archive gathers those source trails into one narrow archive so readers can cite the right page for the right claim.
Disclaimer
Claude Archive is an independent educational publication. It is not affiliated with Anthropic PBC. Claude, Anthropic, Claude Code, and related model names are referenced for editorial and historical identification only.
Claude Network boundaries
Claude Archive owns the dated model timeline. It links to sibling sites for adjacent topics instead of duplicating them: Claude Central for which model to use now, Claude Reports for pricing and benchmark analysis, Claude Weekly for weekly reaction, Claude Ships Code for engineering practice, Claude Memories for memory workflows, Claude Context for context engineering, and Claude Logs for session observability.
The line is tense, not date. A rate this archive records as a September 1, 2026 event is history; the same rate quoted as what you will pay today is Claude Reports' and Claude Central's work.
