OpenAI sets GPT-4 API retirement date for January 2027
OpenAI says it will retire GPT-4o, GPT-4o mini, GPT-4.1, and GPT-4.1 mini from its API on January 14, 2027, along with their snapshots and fine-tuned derivatives. The company recommends GPT-6 Luna as the replacement, but migration may require code and workflow changes because Luna handles reasoning, tool use, and API behavior differently from GPT-4-era models.
