Astra's no-CoT limits track speculative depth, not step count

tl;dr I have tested Astra's ability to complete various long multi-step tasks without using its chain-of-thought, and found that the number of sequential steps is a poor predictor of task success. Instead, Astra's ability to solve a task seems to correlate more strongly with what I will call the speculative depth of the task. Based on experimental results, it seems less likely that Astra solves sequential no-CoT tasks purely by reasoning step-by-step in latent space. Instead, Astra appears to do...
