You can just use it and see for yourself. It's quite good. I do believe they were honest in the paper, but the $5.5m training cost (for v3) is defined in a limited way: only the GPU cost at $2/hr for the one training run they did that resulted in the final V3 model. Headcount, overhead, experimentation, and R&D trial costs are not included. The paper had something like 150 people on it, so obviously total costs are quite a bit higher than the limited scope cost they disclosed, and also they didn't disclose R1 costs. Still, though, the model is quite good, there are quite a few independent benchmarks showing it's pretty competent, and it definitely passes the smell test in actual use (unlike many of Microsoft's models which seem to be gamed on benchmarks).
