The painstaking effort of retraining large language models (LLMs) to acquire new knowledge daily is now a thing of the past, thanks to the cutting-edge MeMo framework. Developed by a team of researchers eager to liberate us from the tyranny of continuous AI retraining, MeMo cleverly channels new information into a petite, peripheral MEMORY model. This Herculean feat allows the dedicated EXECUTIVE model to remain blissfully ignorant of its newfound intelligence, undisturbed by the chaos around it.

MeMo adopts a modular architecture that humorously avoids the throes of complexity brought on by traditional methods. It deftly sidesteps the accuracy-killing catastrophic forgetting occasionally shared among models seeking new acquaintances within their parameters. "Finally, an AI model that is as stubborn as your grandfather when it comes to updating himself," enthused fictional Microsoft spokesperson, Alexa Spreadsheetson.

Enterprises besieged by torrents of ever-evolving data have found a savior in MeMo's innovative 'model merging' method. By surgically implanting updates directly into the MEMORY model rather than dragging the entire LLM family through another round of training, companies can now update knowledge seamlessly, except for the pesky 11% to 19% accuracy drop—considered a feature by some optimistic marketers.

MeMo's glory doesn’t stop there! It reigns supreme in long-document reasoning, taking on challenges like synthesizing arcane regulatory frameworks or unraveling vast codebases effortlessly. Meanwhile, other methodologies struggle, dragging their feet amidst context window limits and irrelevant document noise.

Ending the retraining reign of terror, MeMo surely positions itself as the driving force toward a universe where AIs take in new information as sporadically as their human creators update their software—very occasionally.
