3. Production Migration Checklist (claude-3-haiku-20240307 → claude-haiku-4-5-20251001)

Follow this deterministic engineering sequence before retiring pinned snapshots in production services and SDK clients:

  1. Inventory pinned model IDs: Search repositories and deployment manifests for ANTHROPIC_MODEL, anthropic/ LiteLLM routes, and dated snapshot strings in the Claude 3 Haiku family (1 deprecated, 2 retired, 0 active variants tracked).
  2. Benchmark successor quality & token pricing: Validate structured output schemas, tool-calling payloads, and latency against claude-haiku-4-5-20251001, then compare input, output, and cached token rates in DevToken.
  3. Enforce keyless CI guardrails: Wire RSS, Atom, iCal feeds & CI Guard into pull-request checks so retired or deprecated Claude 3 Haiku identifiers cannot re-enter production.

Compare sibling model families or inspect full provider-level schedules across every ecosystem hosting this family:
