Anthropic provides 60-day advance notice for API model retirements but silently removes models from the claude.ai model picker without equivalent user notification, creating a policy inconsistency for consumer users.

What is this?
Anthropic publishes a deprecation policy committing to at least 60 days' notice before retiring publicly released models on its API and first-party platforms (Claude Platform on AWS, Microsoft Foundry). The policy explicitly excludes partner-operated platforms (Bedrock, Vertex) which set their own schedules. The case alleges a gap: models are removed from the claude.ai consumer model picker without equivalent advance notice to users, creating an inconsistency between API/developer and consumer surfaces. The supplied snippets confirm the 60-day API policy and the partner-platform carve-out, but do not directly document silent removals from claude.ai — the evidence for that claim rests on the case's canonical anchor, not the web results.
Why it matters to Scott
This case is a concrete, documented instance of the exact failure mode Scott's model-perishability and vendor-lock-in frameworks warn against: a major lab providing explicit exit rights (60-day notice) for API/developer surfaces while silently removing models from the consumer doorway (claude.ai) without equivalent notice. It validates his argument that retail AI clients are doorways where engagement continuity must belong to the platform, not undocumented chat-memory behavior, and that counterparty delete-tests expose when vendors treat humans as disposable. This is a dated-receipts opportunity — Scott has the framework; Anthropic just supplied the case study.
