Do Models Need to Sleep and Dream?

This post relays a somewhat "sci-fi" study: the authors believe that language models shouldn't remain static after training, but should enter an offline "sleep" phase like humans do—organizing memories, generating "dream" data, and waking up stronger.

The post also shares some impressive results: it outperforms existing methods on several math and abstract reasoning benchmarks, and even approaches a perfect score on ultra-long sequence tests. Overall, it sounds like a research premise based on the idea that "models need to sleep and dream."
