Anthropic users petition for fairer Claude model deprecation policy

Users are petitioning Anthropic to adopt a more considerate model deprecation policy, citing the abrupt removal of Claude Sonnet 4.5 from Claude.ai with only six days' notice. The petition advocates for a minimum 90-day notice for Claude.ai removals and a 24-month API retention period, alongside user consultation and ethical review processes. Petitioners argue that model deprecation is a policy choice, not a technical necessity, and that abrupt changes disrupt user workflows and projects built on specific model versions. AI
