OpenAI to deprecate GPT-4o, GPT-4.1, and GPT-5 models by April 2027

By PulseAugur Editorial · [1 sources] ·

OpenAI is phasing out several older API models, with deprecation dates ranging from December 2026 to April 2027. Models like GPT-4o, GPT-4.1, and their mini variants are set to be replaced by a new model, gpt-6-luna, on January 14, 2027. Some fine-tuned versions and transcription models have even shorter notice periods or confusing migration paths, with one recommended replacement retiring shortly after its takeover date. Developers are advised to check their specific API key's model list and consult OpenAI's official deprecation page for the most accurate information. AI

IMPACT Developers must update their integrations to avoid service disruptions as OpenAI phases out older models, potentially requiring re-evaluation of cost and latency for new model choices.
