Jurin AI ships JJ-1, Japanese business decision models, with 0.8B and 2B weights under CC BY-NC
On 13 October 2026 Tokyo-based Jurin AI announced JJ-1, a decision model family for Japanese enterprise workflows: which team gets a request, how urgent it is, whether to escalate. The press release went out on PR Times and EIN Presswire.
The family has four sizes. JJ-1-0.8B and JJ-1-2B are on Hugging Face with BF16 and Q8_0 GGUF weights, a CLI and a /v1/systemone server. The weights are CC BY-NC 4.0, modified from StartLux-Decision-2B. The 4B and 9B are private, and a hosted service needs sign-up.
Jurin’s numbers (UnverifiedClaim): JJ-1-9B 79.20% over 84,153 hard-label questions in six areas, against 76.50% for Jev 1.13 and 71.35% for GPT-6 Luna Decisions; 97.43% on 6,033 Japanese workflow questions; 8–30 ms per request on one B200. The public 2B scores 68.54% on the same report.
