USE MULTIPLE MODELS

Problems with AI models can often be solved by passing the same query to a peer model. This suggests that models are actually quite close to being able to solve many tasks, but they're just not there yet. For switching to regularly solve tasks, each model must have a fairly high probability of success. The next generation of models will be even more capable.
