DEEPSEEK FAQ

DeepSeek's R1 model, which is similar to OpenAI's o1, caused a meltdown in the tech industry over the weekend. Many of the revelations that contributed to the meltdown were included in DeepSeek's announcement over Christmas and most of the breakthroughs in V3 were actually revealed with the release of the V2 model last January. DeepSeek-V2 introduced two important breakthroughs, DeepSeekMoE and DeepSeekMLA - the implications of these breakthroughs only became apparent with V3, which added a new approach to load balancing and multi-token prediction in training. The cost of training the model amounted to only $5.576 million, but that excludes the costs associated with prior research, experiments, and data. Many of the decisions DeepSeek made in training its model were due to the constraints of the chip ban - if DeepSeek had access to more powerful chips, it probably would have used a different method.

HUGE STUDY FINDS CONSTELLATION OF HEALTH BENEFITS FOR OZEMPIC BEYOND WEIGHT LOSS

A new study that tracked millions of diabetes patient outcomes over a period of 3.5 years found that those on GLP-1 medications saw significant improvements across a staggering range of health concerns, far beyond anything clearly linked to weight or blood sugar. The patients experienced improvements in addiction and psychotic disorders and the risk of Alzheimer's was decreased. GLP-1RA drugs act on receptors that are expressed in brain areas involved in impulse control, reward, and addiction, which may potentially explain their effectiveness in curbing appetite and addiction disorders. While the findings are positive, the researchers found some issues that seemed to be exacerbated by taking GLP-1s, including an increase in risk for arthritis and pancreatitis.
