AutoJev-27B

Built with autonomous agents, from research and data generation to training, evaluation, and deployment. The user set the goals and refined the scope; agents executed the work.

AutoJev-27B is a multimodal decision model based on Qwen3.8-27B. It returns probabilities over supplied choices in one forward pass per question, with a TypeSafe-compatible API and browser playground.

Results

Training

One H200 · full-weight SFT · 73,000 unique training examples · 286 updates. The released model is checkpoint 200. Training uses cross-entropy; calibration fits a scalar temperature separately.

Run bash configs/train.sh --help for training arguments. The exact curated training corpus is not bundled.

Run

Python 3.12+, uv and a GPU with space for approximately 49 GiB of BF16 weights plus runtime overhead.

git clone https://github.com/denis-pplx/autojev.git
cd autojev

Open http://localhost:8000 for the playground or /docs for the API. POST /v1/systemone supports choice, noul, score, and optional base64 images. Set AUTOJEV_API_KEY to enable authentication. While the weights are private, authenticate with uv run hf auth login before downloading.

Use the included DecisionModel loader or server. Published benchmarks measure text decisions; image support is not a natural-image accuracy claim.
