**Local text classification, workflow routing, and fixed-choice scoring with JevStyle.** This 0.8B v3 release is the package’s default text decision model. It accepts text and JSON, not images; its PyTorch, MLX, and GGUF distributions require the matching decision runtime. Maintained by **Chaoliang Yan** (GitHub: `lawrence3699`), as an independent project, not affiliated with TypeSafe AI. Training provenance is specific to each release; see this card’s training section. The separate 2B v4 release discloses soft-label distillation from TypeSafe Jev 1.14 through its public API. Choose a workflow: local text classification in Python · choosing a local decision model · this model’s setup and limits · evaluation evidence.

> **Hosted API status · 2026-10-28:** The hosted API is temporarily unavailable for maintenance. For a working first try, open the browser demo (2B v4), or run the open weights locally. Service information. **Quickest start: the jev-style package** (0.3.0 or later) downloads these files and serves a local `/v1/systemone` API. It needs this repository's scorer, `jev-score-v2`, built once from `build_jev_score.sh` (see the Quick start below): **Jev-style decisions, now at 2B, for llama.cpp.** These are the GGUF builds of Jev-Style-2B-Decision-v3: F16, Q8_0 and a **1.27 GB** Q4_K_M, with a small bundled scorer (`jev-score-v2`) that reads the decision at one verdict slot per option. Full results, protocols, training data and licences are on the main model card.

读懂模型,再做选择

选型与常见问题
API 价格应该怎么比较?+

先区分输入、输出和缓存价格,再使用同一任务和用量估算总费用。图像、音频和视频可能按张、时长或分辨率计费,不能直接与 Token 单价比较。

开放权重,就代表可以免费商用吗?+

不一定。必须逐一核对具体模型版本的许可证、商用限制及使用政策。自己部署还需要考虑显存、推理资源和运维费用。

排行榜第一,就是最适合我的模型吗?+

榜单取决于测试任务、版本与评测方法。建议用实际业务样本比较准确性、时延、稳定性和成本,再选择模型。
