3. Production Migration Checklist (gpt-5-2025-08-07 → gpt-5.6-sol)
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-5, GPT-5.1 – GPT-5.5 & Codex family (34 deprecated, 16 retired, 7 active variants tracked). - Benchmark successor quality & token pricing: Validate structured output schemas, tool-calling payloads, and latency against
gpt-5.6-sol, 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-5, GPT-5.1 – GPT-5.5 & Codex identifiers cannot re-enter production.
