SantaCoder's impressive but that's probably misleading. It's reported that incoder doesn't generate as diverse a set of solutions but does do better at the ones it generates. This means it performs well at a lower number of tries when compared to other similar models, which is what matters in practice. The numbers reported here required many trials.

With a fuller context and just a handful of tries, it's unlikely that 6.7B version of incoder will be outperformed by SantaCoder.
