Users on Reddit are reporting significant changes in OpenAI's models, particularly concerning the "Sol High" setting for Chat and Codex. In Chat, users note a loss of reasoning chains, instant replies without apparent thought, and a degradation in output quality, including sudden swearing and a failure to cite sources. The Codex model is also described as no longer following instructions or documentation as effectively, requiring more revisions and proactively using user-created skills. These changes are leading to frustration and speculation about A/B testing or a broader rollout of a new model version, with one user reporting the model identifying itself as "GPT 5.6 Sol." AI
