Aliases such as gpt-daybreak-blue-latest currently point to GPT-5.6 Sol and GPT-5.6 Cyber, respectively. When new models are released, these aliases will automatically switch to the latest models. Pricing will be adjusted according to each base model.
Furthermore, OpenAI is scaling back its fine-tuning platform. Access for new users has been suspended, although existing users will remain able to create training jobs for several months.
Fine-tuned models are reported to remain available for inference until the corresponding base model is deprecated. The specific schedule can be confirmed via the company's timeline.
