The Prompt API isn't available in Web Workers for now, due to the complexity of establishing a responsible document for each worker in order to check the permissions policy status.
大多数人认为现代浏览器API应该支持Web Workers以实现并行处理，但作者明确表示Prompt API不支持Web Workers。这与人们对浏览器API应该全面支持现代Web开发模式的认知相悖，限制了开发者在后台线程中使用AI的能力。
This problem is compounded for proprietary reasoning APIs that expose neither logits nor intermediate token probabilities, leaving practitioners with no reliable uncertainty signal at inference time.
令人惊讶的是：当前许多专有的推理API既不提供logits也不提供中间token概率，这使得实践者在推理时无法获得可靠的不确定性信号。这一被忽视的挑战限制了大型语言模型在实际应用中的可靠性评估，而SELFDOUBT正是为了解决这一特定问题而设计的。
