Microsoft Azure OpenAI and Foundry services will retire multiple models including o1, o1-pro, codex-mini, and Claude Haiku 4.5 in November 2026.
The third wave of retirement occurs on November 19, 2026, when o1, o1-pro, and another five o-series models will be retired together.
Taking OpenAI's o1-pro as an example, a single complex reasoning task may generate tens of thousands of hidden thinking tokens, and the cost can be 5 to 10 times that of normal mode.
