Hey @glebashnik thank you very much for the PR! We worked on a bigger update to the latest llama.cpp version so it had to wait a little, but it should now be merged and released soon. When I just tested it, the json schema to grammar test failed because of a slight difference:
I assume this is due to a change in the implementation since the last version. I hope it's ok that I adapted it. Otherwise everything looks good to me. |

Thank for the fix and new release, @kherud! Indeed, there was a small change in underlying C++ implementation of grammar generator. |

This exposes exposes C++ function to convert JSON schema to GBNF grammar.
GBNF grammar is an inference parameter to generate structured output, which is often useful to reduce hallucinations.
