IANAL, but the problem with these types of licenses (e.g. WTFPL, Beerware, etc) is that they lack any liability/warranty clauses. If you want a simple, open-as-possible license, you should generally just go with MIT or a similar (and well-known) license.
This MIT-licensed model is 500 times smaller than GPT-4o and claims to outperform it in some benchmarks. Seems useful for tasks requiring extraction of data to JSON.
