NeoHorse-Jev-4B

Hugging Face card for NeoHorse-Jev-4B: Apache-2.0 4B decision model for text or image-plus-text, served at /v1/systemone.

ModelbetaApache-2.0

Overview

This is the Hugging Face model card for NeoHorse-Jev-4B, TokenRhythm's 4B structured decision model fine-tuned from NeoHorse-1-4B. Given a state and application-defined questions, it predicts decisions and probabilities for routing requests, selecting tools, checking conditions and rating outcomes, using prefill-only inference without autoregressive generation. Text requests can include multiple questions, and optional image requests combine a single image with text.

The card reports a 77.70 six-group text aggregate, highest among four open-weight decision models with complete results, and 83.26% mean accuracy on Nimble, VitaminC and MASSIVE. It also shows six decision demos: Tetris, Snake, robot manipulation, Mahjong, a four-player bomb arena and autonomous driving. Deployment options are vLLM, SGLang and a native Python, CLI and HTTP runtime serving /v1/systemone. The GitHub repository covers the wider NeoHorse family.

How it works

  1. Download the weights from Hugging Face.
  2. Serve with vLLM, SGLang or the native runtime at /v1/systemone.
  3. Send text (or one image plus text) with questions.
  4. Use probabilities and expected ratings in routing rules.

Strengths

  • Open Apache-2.0 weights with image support.
  • Jev-compatible endpoint shape.
  • Demonstrated on games, robotics and driving tasks.

Caveats

  • Evaluations are by the model authors.
  • Image requests limited to a single image.

Getting started

Download TokenRhythm/NeoHorse-Jev-4B from Hugging Face and serve it with vLLM, SGLang or the native runtime.
