OpenAI retires legacy Codex API aliases July 23
Archive item — written before sources were shown.
OpenAI confirmed that gpt-5-codex, o3-deep-research, computer-use-preview, and 11 additional legacy model aliases will stop accepting requests on July 23, 2026.
The July 23 sunset is the first in a two-wave sequence: an October wave covers GPT-4 and o1-lineage models, giving teams on older endpoints a harder deadline.
