Julia 1

Supersonic Labs

Released: -
Data date: October 3, 2026

Model class: Multilingual decision model for classification and routing, not a chat model
Access: Local PyTorch or ONNX execution

Julia 1 is Supersonic Labs’ first checkpoint in the Julia family, with 144.3 million parameters. The multilingual model processes a state, a question, and possible answers, then returns Choice, Noul, or Score. It fits classification and routing while keeping the readout structured instead of producing a free-form explanation.

It is based on jhu-clsp/mmBERT-small. Local PyTorch or ONNX execution supports up to 8,192 runtime tokens under an Apache-2.0 license.
