# OpenAI GPT-4 32k — deprecation status

> Yes — GPT-4 32k is retired. OpenAI deprecated it on June 6, 2024 and shut it down on June 6, 2025; API requests to it now fail. The recommended replacement is GPT-4o.

The 32,000-token variant of the original GPT-4, sold at twice the price of the 8k model when a long context was still a premium feature. Access was gated behind a waitlist for most of its life, so it never had the reach of plain gpt-4. GPT-4o made it redundant: 128k of context, faster, and cheaper than the 8k model it replaced.
