ProsQA

A new arXiv preprint (2609.03090v1) reports that matrix-CODI, a continuous chain-of-thought model with matrix-valued latent bottlenecks, shows rank-indifference on the ProsQA benchmark: rank-k project…

A study by researchers testing the Coconut and CODI models found that these latent reasoning models barely use their hidden reasoning steps for logical tasks like PrOntoQA and ProsQA, with performance…
