OpenAI to retire 15 models, including Codex, on July 23, 2026

By PulseAugur Editorial · [1 sources] ·

OpenAI is scheduled to retire approximately 15 of its AI models, including five from the Codex family, on July 23, 2026. This deprecation will affect production endpoints, potentially causing them to stop responding without advance error notification. The article advises users to test recommended replacements, noting that current generation models like GPT-5.6 (GPT-5.6 "Sol", gpt-5.6-terra, GPT-5.6-luna) are suggested alternatives. A tool is also mentioned for tracking retirement dates across OpenAI, Anthropic, and Google. AI

IMPACT Users of OpenAI models need to migrate to newer versions before July 2026 to avoid service disruptions.
