What it does

Hugging Face hosts the 0.8B and 2B models under a non-commercial licence. The vendor’s technical report evaluates 4B and 9B versions for fast, structured business decisions, but those larger versions may be hosted-only. Independent benchmarks are not available for them.

How you can use it

For Japanese business questions, JJ-1 selects answers instead of composing replies. You can run the released 0.8B and 2B models locally, provided the use is non-commercial. The larger models’ results are from Jurin’s report, not independent tests of downloadable versions.
