"The big improvement is a new feature called DSA (DeepSeek Sparse Attention), which makes the AI better at handling long documents and conversations. The pros and cons of sparse attentionAn AI model makes decisions based on its training data and new information, such as a prompt. "The reality is, they [sparse attention models] have lost a lot of nuances," said Almasque, who was an early supporter of Dataiku and Darktrace, and an investor in Graphcore. "And then the real question is, did they have the right mechanism to exclude not important data, or is there a mechanism excluding really important data, and then the outcome will be much less relevant?" This could be particularly problematic for AI safety and inclusivity, the investor noted, adding that it may not be "the optimal one or the safest" AI model to use compared with competitors or traditional architectures.
