Δ-Mem: Efficient Online Memory for Large Language Models

This doesn’t solve the capacity problem of memory. You can cram more into one context window, but then again you need to associate them with input queries. That’s very hard because slight variations in input create hugely different activations. So really, it doesn’t improve caching. This paper might do a thing or two approximating the compression limit for context windows, but there’s a fundamental limit on how much information can go into it. What you really need is contextual search, as in, different events and objects with the same abstractions and semantic lead to same response, so you can cache effectively… on this front the paper does little to improve “memory” in a meaningful way

- fixed size of the memory seems like a good idea to overcome the current limitations

- skimming through the thing, I can't find any mention of the cost?

- I would need more time to read it in-depth to see if this is legitimate and not just fancy form of overfitting or training on testing data

Is it a lowercase to uppercase conversion going on here?

(Obviously ignoring the huge energy saver, which is to observe if you even need to bother doing the task at all.)

What I want to see is something that was tested and proved in practice to be genuinely useful, especially for coding agents.
