Nous-Hermes-2-Vision - Mistral 7B

In the tapestry of Greek mythology, Hermes reigns as the eloquent Messenger of the Gods, a deity who deftly bridges the realms through the art of communication. It is in homage to this divine mediator that I name this advanced LLM "Hermes," a system crafted to navigate the complex intricacies of human discourse with celestial finesse.

Model description

Nous-Hermes-2-Vision stands as a pioneering Vision-Language Model, leveraging advancements from the renowned OpenHermes-2.5-Mistral-7B by teknium. This model incorporates two pivotal enhancements, setting it apart as a cutting-edge solution:

• SigLIP-400M Integration: Diverging from traditional approaches that rely on substantial 3B vision encoders, Nous-Hermes-2-Vision harnesses the formidable SigLIP-400M. This strategic choice not only streamlines the model's architecture, making it more lightweight, but also capitalizes on SigLIP's remarkable capabilities. The result? A remarkable boost in performance that defies conventional expectations.

• Custom Dataset Enriched with Function Calling: Our model's training data includes a unique feature – function calling. This distinctive addition transforms Nous-Hermes-2-Vision into a Vision-Language Action Model. Developers now have a versatile tool at their disposal, primed for crafting a myriad of ingenious automations.

This project is led by qnguyen3 and teknium.

Training

Dataset

• 220K from LVIS-INSTRUCT4V
• 60K from ShareGPT4V
• 150K Private Function Calling Data
• 50K conversations from teknium's OpenHermes-2.5

Usage

Prompt Format

• Like other LLaVA's variants, this model uses Vicuna-V1 as its prompt template. Please refer to conv_llava_v1 in this file
• For Gradio UI, please visit this GitHub Repo

Function Calling

• For functiong calling, the message should start with a <fn_call> tag. Here is an example:

<fn_call>{
  "type": "object",
  "properties": {
    "bus_colors": {
      "type": "array",
      "description": "The colors of the bus in the image.",
      "items": {
        "type": "string",
        "enum": ["red", "blue", "green", "white"]
      }
    },
    "bus_features": {
      "type": "string",
      "description": "The features seen on the back of the bus."
    },
    "bus_location": {
      "type": "string",
      "description": "The location of the bus (driving or pulled off to the side).",
      "enum": ["driving", "pulled off to the side"]
    }
  }
}

Output:

{
  "bus_colors": ["red", "white"],
  "bus_features": "An advertisement",
  "bus_location": "driving"
}
