In other AI-related news, Nvidia researchers have developed a technique called dynamic memory sparsification (DMS) that can reduce the memory costs of large language model (LLM) reasoning by up to eight times, VentureBeat reported. This method compresses the key value (KV) cache, the temporary memory LLMs use, without significantly degrading the model's performance. Experiments showed that DMS allows LLMs to "think" longer and explore more solutions.
