GPT-4 Turbo preview (1106) (OpenAI)
Yes — OpenAI deprecated GPT-4 Turbo preview (1106) on September 26, 2025 and shuts it down on October 23, 2026 (in 85 days). The recommended replacement is GPT-5.6 Sol.
The November 2023 preview that introduced 128k context and JSON mode, and the one entry on this site with two conflicting shutdown dates: OpenAI first set it for March 26, 2026, then listed the same id again in the April 2026 announcement with a new date of October 23, 2026. The later announcement is the one that stands.

What to use instead
JSON mode has been superseded by structured outputs, which enforce a schema rather than only guaranteeing valid JSON. Worth adopting during the move instead of after it.
