plus a simple heuristic (update what’s specific, leave what’s general) that sidesteps the need to learn how to learn. There was a lot of hype around the (very lengthy) paper from DeepMind on nested learning, which starts with the observation that architecture and optimization aren’t separate things. Rather, they’re the same concept operating at different timescales. A transformer’s attention mechanism is associative memory updating every forward pass. The feedforward layers are associative memo

This will enable Anthropic to be, alongside Google DeepMind, the only AI labs benefiting from tight hardware–software co-design in the near horizon.

e optimizations to improve how memory can be efficiently used. Ollama configures causal attention at the individual model level instead of configuring as a group. Examples: Google DeepMind’s Gemma 3 leverages sliding window attention, and Ollama can leverage that to allocate a subset or a portion of the model’s context length to improve performance, and because of the resulting memory efficiency, we can increase the context length of the model on the same system or use the remaining memory for h
