Ultra模式
ChatGPT GPT-5.6中的最高推理强度模式，能够根据任务复杂度自动调用多个子代理进行并行工作，采用多Agent协作架构，默认并发子线程上限为6，委派层级为1
Timeline (last 90 days)
Google's rumored Ultra mode, and similar enhanced-thinking modes in the industry, require users to give up millisecond-level instant responses in exchange for the AI using minutes or even hours of compute time to plan, test, and verify work.
Ultra mode corresponds to more complex, compute-intensive tasks where fixed high-intensity computation accounts for a larger share of the cost structure, leaving relatively limited room for optimization.
The user had to keep Astra running in Ultra mode throughout; otherwise the model would start going in circles and be unable to make progress.
