`gpt-daybreak-blue-latest` and `gpt-daybreak-red-latest` are aliases that currently point to `gpt-5.6-sol` and `gpt-5.6-cyber`, respectively. As new models are released through the Daybreak program, these aliases will be updated to point to the latest models, with pricing adjusted to match each underlying model.

Tokens used for built-in tools are billed at the chosen model's per-token rates. GB refers to binary gigabytes (also known as gibibytes), where 1 GB is 2^30 bytes. Web search content tokens are tokens retrieved from the search index and fed to the model alongside your prompt to generate an answer. For `gpt-4o-mini` and `gpt-4.1-mini` with the non-preview web search tool, search content tokens are billed as a fixed block of 8,000 input tokens per call. File search tool call pricing applies to the Responses API only. Container pricing includes Hosted Shell and Code Interpreter. Eligible container sessions will be billed by the minute, with a 5-minute minimum per session. Responses API, Chat Completions API, Realtime API, Batch API, and Assistants API are not priced separately. Tokens are billed at the chosen model's input and output rates.

Finetuning
Prices per 1M tokens.
OpenAI is winding down the fine-tuning platform. The platform is no longer accessible to new users, but existing users of the fine-tuning platform will be able to create training jobs for the coming months.
All fine-tuned models will remain available for inference until their base models are deprecated. The full timeline is here.
