Our first run on Psyche will pretrain a 40B parameter model using the Multi-head Latent Attention (MLA) architecture across 20T tokens, which we're naming Consilience. This represents the largest pretraining run conducted over the internet to date, surpassing previous iterations that trained smalle...
For instance, if u(x,t) represents the displacement of a vibrating violin string at time t and at a distance x from one end of the string, then u(x,t) satisfies the wave equation. Here the constant a depends on the density of the string and on the tension in the string....
