3. Production Migration Checklist (gpt-4o-2024-08-06 → gpt-6-luna)
Follow this deterministic engineering sequence before retiring pinned snapshots in production services and SDK clients:
- Inventory pinned model IDs: Search repositories and deployment manifests for
OPENAI_MODEL,openai/LiteLLM routes, and dated snapshot strings in the GPT-4o family (6 deprecated, 3 retired, 0 active variants tracked). - Benchmark successor quality & token pricing: Validate structured output schemas, tool-calling payloads, and latency against
gpt-6-luna, then compare input, output, and cached token rates in DevToken. - Enforce keyless CI guardrails: Wire RSS, Atom, iCal feeds & CI Guard into pull-request checks so retired or deprecated GPT-4o identifiers cannot re-enter production.
