OpenAI has introduced a new model, with some reports specifying it as GPT-5.1, while others mention GPT-5.1-Codex-Max or GPT-5.2. The model is said to have various features, including adaptive reasoning and personalization, as well as coding capabilities. However, the exact details and naming of the model are not consistent across reports, with some outlets also mentioning alternative models, such as Claude Opus 4.5 from Anthropic.
