The information reports Astra reportedly uses "recurrent depth," or a "looped transformer," which helped its performance while making some internal reasoning less readable.
据报道，Astra 使用的信息报告包含“循环深度”或“循环 Transformer”，这有助于提升其性能，但使得部分内部推理过程的可读性降低。
A looped transformer, or recurrent-depth model, can run the same information through the same transformer layers multiple times before producing the next token, instead of passing through each layer just once in a fixed stack.
循环 Transformer（或称循环深度模型）可以在生成下一个 token 之前，将相同的信息多次通过相同的 Transformer 层进行处理，而不是在固定的堆栈中仅经过每层一次。
That gives the model more computation per token without proportionally increasing its parameter count, potentially letting a smaller model behave more like a larger one while using less memory and bandwidth.
这使得每个 token 的计算量增加，而参数数量并未成比例增长，从而可能让较小的模型表现出类似较大模型的行为，同时使用更少的内存和带宽。
The concern is that more of this reasoning can happen inside internal numerical states rather than readable chain-of-thought text, making human monitoring harder.
令人担忧的是，更多的推理过程可能在内部数值状态中进行，而非以可读的链式思维文本形式呈现，这使得人工监控变得更加困难。
