LlamaV-o1

Overview

LlamaV-o1 is an advanced multimodal large language model (LLM) designed for complex visual reasoning tasks. Built on a foundation of cutting-edge curriculum learning and optimized with techniques like Beam Search, LlamaV-o1 demonstrates exceptional performance across diverse benchmarks. It is fine-tuned for step-by-step reasoning, enabling it to tackle tasks in domains such as visual perception, mathematical reasoning, social and cultural contexts, medical imaging, and document understanding.

The model is designed with a focus on interpretability and precision. By leveraging a structured reasoning approach, LlamaV-o1 provides coherent and accurate explanations for its decisions, making it an excellent tool for research and applications requiring high levels of reasoning. With over 4,000 manually verified reasoning steps in its benchmark evaluations, LlamaV-o1 sets a new standard for multimodal reasoning, delivering consistent and reliable results across challenging scenarios.

Key Features:

• Model Size: 11 billion parameters.
• Architecture: Based on the Llama (Large Language Model Architecture) family.
• Fine-Tuning: Enhanced for instruction-following, chain-of-thought reasoning, and robust generalization across tasks.
• Applications: Ideal for use cases such as conversational agents, educational tools, content creation, and more.

Evaluation

Benchmarks

LlamaV-o1 has been evaluated on a suite of benchmark tasks:

• Reasoning: VRC-Bench

Limitations

While the model performs well on a broad range of tasks, it may struggle with:

• Highly technical, domain-specific knowledge outside the training corpus.
• Generating accurate outputs for ambiguous or adversarial prompts.

Usage

from transformers import MllamaForConditionalGeneration, AutoProcessor

model_id = "omkarthawakar/LlamaV-o1"

model = MllamaForConditionalGeneration.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
processor = AutoProcessor.from_pretrained(model_id)

Results

Table 1: Comparison of models based on Final Answer accuracy and Reasoning Steps performance on the proposed VRC-Bench. The best results in each case (closed-source and open-source) are in bold. Our LlamaV-o1 achieves superior performance compared to its open-source counterpart (Llava-CoT) while also being competitive against the closed-source models.

Training Data

LlamaV-o1 is trained on the LLaVA-CoT-100k dataset. We have formatted training sample for multi-step reasoning.

Training Procedure

LlamaV-o1 model is finetuned on llama-recipes. Detailed Training procedure will be coming soon!
