OpenAI to retire GPT-4o and legacy models from ChatGPT
🔔 OpenAI said it will retire the popular GPT-4o model on February 13, 2026, along with several other models, including GPT-5 Instant, GPT-5 Thinking, GPT-4.1, and o4-mini. The company said the move follows the rise of GPT-5.2, which it now regards as meeting expectations for capability and safety. OpenAI introduced a Personality feature to help users replicate aspects of GPT-4o’s warmer, conversational style, and said API behavior is unchanged at this time.
