Introduction

Logics-Parsing-Omni is a unified Multimodal Large Language Model (MLLM) designed to bridge the gap between pixel-level structural parsing and semantic-level cognitive captioning. It provides strong performance in both fine-grained perception and high-level semantic understanding across documents, images, audio, and video.

Showcase of the multifaceted capabilities of Logics-Parsing-Omni

Key Features

• Omni-Modal Unified Parsing Framework

  • It introduces a progressive three-level paradigm—integrating Holistic Detection, Fine-grained Recognition, and Semantic Interpretation—that fundamentally bridges the gap between pixel-based perception and logic-based cognition.
  • It transforms unstructured multimodal signals into a standardized, machine-readable schema that is inherently Locatable, Enumerable, and Traceable, forming an indispensable part of fact-based reasoning chains.

• Knowledge-Intensive Document & Graphic Interpretation

  • Surpassing traditional OCR and generic LLM pipelines, it jointly parses structural elements (e.g., dense text, layout, tables, formulas) and deep semantics (e.g., complex illustrations) with high layout fidelity.
  • It overcomes the bottleneck of generic image understanding by explicitly extracting dense, attribute-rich underlying data series, axis labels, and spatial topologies from scientific charts and technical diagrams to support reasoning.

• Long-Form Audio-Visual & Educational Content Parsing

  • Moving beyond flat ASR linear transcripts and generic video summaries, it dynamically synchronizes audio cues with critical visual contexts, explicitly capturing missed details like slides, whiteboards, and code.
  • It is specifically optimized for long-form educational videos, successfully extracting structured pedagogical organizations (e.g., chapter hierarchies, key concepts) and dynamic narrative logic while mitigating information redundancy and topic drift.

• Data-Centric Optimization & Comprehensive Benchmarking

  • Powered by a meticulously constructed omni-modal dataset, the Logics-Parsing-Omni model establishes a robust balance between fine-grained structural fidelity and deep semantic interpretation.
  • Alongside the model, it introduces OmniParsingBench, a standardized evaluation infrastructure designed to quantitatively assess the full spectrum of parsing capabilities across documents, images, audio, and videos.

OmniParsingBench Evaluation

To rigorously evaluate the unified parsing capabilities of our model across diverse modalities, we introduce OmniParsingBench—a comprehensive, large-scale evaluation corpus. It assesses the full spectrum of parsing performance across six primary domains: Natural Image, Graphics, Document, Audio, Natural Video, and Text-Rich Video.

To provide a concise view of model capabilities, we aggregate fine-grained metrics into three core scores:

• Perception (Perc.): Evaluates signal precision and structural fidelity (e.g., spatio-temporal grounding, symbol extraction).
• Cognition (Cog.): Evaluates logical reasoning, semantic understanding, and hallucination resistance.
• Overall (Ovr.): The comprehensive performance metric. Full evaluation details are released in the technical report.

As detailed in the tables above, Logics-Parsing-Omni demonstrates highly competitive capabilities across all diverse modalities:

• Dominance in Complex Modalities: Our model consistently surpasses all evaluated baselines—including the leading proprietary Gemini-3-Pro—in the Graphics, Audio, and Text-Rich Video domains.
• Exceptional Cognitive Reasoning: The superiority is particularly pronounced in the Cognition metric. Logics-Parsing-Omni exhibits exceptional logical reasoning and semantic understanding, achieving top-tier scores such as 92.12 in Graphics and 80.85 in Text-Rich Video. These results firmly validate that our model successfully bridges fundamental signal detection with complex multi-modal interpreting.

Quick Start

1. Installation

conda create -n logics-parsing-omni python=3.10
conda activate logics-parsing-omni

pip install -r requirements.txt

2. Inference

We provide a unified multimodal inference script (inference_omni.py) that supports 12 pre-defined tasks across 4 different modalities (Single Image, Multi-Image, Audio, and Video).

You can easily test different capabilities using the --task argument. Additionally, all pre-defined tasks support bilingual prompts. You can switch between English and Chinese using the --language argument (en or ch, defaults to en).

Option A: Run a Pre-defined Task

Test a specific capability using built-in prompts and assets by passing the corresponding task name and your preferred language:

# Example: Run the natural video parsing task with the English prompt (default)
python inference_omni.py --task natural_video_parsing --language en

# Example: Run the document structure parsing task with the Chinese prompt
python inference_omni.py --task document_structure_parsing --language ch

Option B: Run a Custom Task (CLI Mode)

If you want to test your own files and prompts, use the --task custom mode along with the specific modality argument. (Note: The --language argument is ignored in custom mode since you provide the prompt directly).

# Example 1: Single Image Inference
python inference_omni.py --task custom \
    --image_paths path/to/image.jpg \
    --text_prompt "Describe the content of this image."

# Example 2: Multi-Image Inference
python inference_omni.py --task custom \
    --image_paths path/to/image1.jpg path/to/image2.jpg \
    --text_prompt "What are the differences between these two images?"

# Example 3: Single Audio Inference
python inference_omni.py --task custom \
    --audio_path path/to/audio.wav \
    --text_prompt "Please transcribe this audio."

# Example 4: Single Video Inference (with audio extraction)
python inference_omni.py --task custom \
    --video_path path/to/video.mp4 \
    --use_audio_in_video \
    --text_prompt "Please summarize this video."

3. Supported Pre-defined Tasks
