> In the end it took us only a very small number of smaller scale & shorter ablation runs to get to the strong 21B Reka Flash and 7B edge model (and also our upcoming largest core model). Finding a solid recipe with a very limited number of runs is challenging and requires changing many variables at once given the ridiculously enormous search space. In order to do this, one has to abandon the systematicity of Bigtech and rely a lot on “Yolo”, gut feeling and instinct. > Thankfully, I (and many of us in the team) have built up this intuition quite a bit in our ML careers to get it right within a substantially short amount of tries. While we’ve trained really good models before in our previous jobs, differences in training infrastructure, data, incorporation of new ideas and other environmental issues can still cause non-trivial differences in outcomes. That said, a strong prior helps to significantly cut down the search space and is probably one of the easiest explanations to why we were able to train really strong models with so few trials, resources and experimentation.
