What it does

Same API as Jev (/v1/systemone): just change the address in your code
Apache 2.0, public weights and training recipe
A notch below Jev on accuracy, but free, local and with no call limits

! Free alternative to Jev (Apache 2.0). Its local server uses the same API contract as TypeSafe: the official SDK works by changing only the address. Author-published evaluation: 0.82 accuracy against 0.86 for Jev on new sources, with a close confident-error rate (4.0% vs 3.7%). Information from the official repository and tech press.
