Figure 2 in our paper (https://arxiv.org/abs/2307.09702) shows the difference between guidance and outlines to generate a sequence that is valid to a regex. Jsonformer uses the same technique as guidance. Extrapolate this to several fields.

Note that we still need to manage the KV cache in outlines. It’s a small interface change that will be made this week hopefully, but we’ve been focusing on constrained generation so far.

jsonformer uses a template rather than a DFA. The logit masking seems to be identical, though.
