3. Production Migration Checklist (gpt-4-turbo-2024-04-09 → gpt-5.6-sol)

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 OPENAI_MODEL, openai/ LiteLLM routes, and dated snapshot strings in the GPT-4 Turbo family (0 deprecated, 8 retired, 0 active variants tracked).
  2. 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.
  3. Enforce keyless CI guardrails: Wire RSS, Atom, iCal feeds & CI Guard into pull-request checks so retired or deprecated GPT-4 Turbo identifiers cannot re-enter production.

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

5. GPT-4 Turbo Deprecation & Upgrade FAQ

Is GPT-4 Turbo deprecated or retired across OpenAI?

LLMEOL tracks 8 GPT-4 Turbo variants across OpenAI: 0 deprecated with scheduled shutdowns, 8 retired past their UTC EOL date, and 0 active with no announced shutdown date. Check the cross-ecosystem matrix above for exact snapshot dates.

What is the recommended replacement model when migrating off gpt-4-turbo-2024-04-09?

The primary recommended upgrade target for gpt-4-turbo-2024-04-09 is gpt-5.6-sol. Always test prompt formatting, max output tokens, and tool schemas on gpt-5.6-sol, and compare token pricing in DevToken before switching production traffic.

How can I replace gpt-4-turbo-2024-04-09 in .env and LiteLLM configs safely?

Paste your OPENAI_MODEL assignment or LiteLLM model block into the Quick Replacement Matcher on this page to generate an exact diff, or open the full Local Model Config Auditor to scan multi-service manifests with zero network upload.
