"productively increase the number of iterations" should say "productively increase the number of recurrent iterations"
Transparency about the opaque serial depth is great, but this statement is consistent with Astra having a configurable "dial" that is currently set to a low depth but could be trivially increased. We need more info to see how concerning these architectural changes are,I want to prevent a race into unmonitorability kicked off by confused reporting. The depth of the computation graph for our present frontier models, including Astra, is within a factor of two of GPT-4. OpenAI has worked to preserve and utilize chain-of-thought monitoring since- "productively increase the number of iterations" should say "productively increase the number of recurrent iterations"
