Quants

4bpw h6 (main)
5bpw h6
6bpw h6
8bpw h8

Quantization notes

Made with Exllamav3 0.0.29. It can be used with TabbyAPI and perhaps Text-Generation-WebUI on Nvidia RTX3xxx or newer GPUs.
In my brief testing it seemed to work on English texts with the 4bpw quant in OpenWebUI + TabbyAPI but had some messy tokens sometimes.
I think it might require sampler parameters from the original Qwen3-VL-2B-Instruct for better performance.

🔥 FireRed-OCR

FireRed-OCR is a systematic framework designed to specialize general Large Vision-Language Models (LVLMs) into high-performance, pixel-precise structural document parsing experts.

General VLMs frequently suffer from "Structural Hallucination" (e.g., disordered rows, invented formulas) when processing complex documents. FireRed-OCR addresses this by shifting the paradigm from "impressionist" text generation to "structural engineering," achieving State-of-the-Art (SOTA) results on authoritative benchmarks like OmniDocBench v1.5.

✨ Key Features

• SOTA Performance: Achieves 92.94% overall score on OmniDocBench v1.5, significantly outperforming DeepSeek-OCR 2, OCRVerse, and massive general VLMs (e.g., Gemini-3.0 Pro，Qwen3-VL-235B).
• Structural Integrity: Utilizing Format-Constrained GRPO (Group Relative Policy Optimization), the model enforces strict syntactic validity, eliminating common errors like unclosed tables or invalid LaTeX formulas.
• "Geometry + Semantics" Data Factory: A novel data engine that uses geometric feature clustering and multi-dimensional tagging to synthesize balanced datasets, effectively handling long-tail layouts.
• Progressive Training Pipeline:
  1. Multi-task Pre-alignment: Establishes spatial grounding.
  2. Specialized SFT: Standardizes full-image Markdown output.
  3. Format-Constrained GRPO: Self-correction via Reinforcement Learning.
• In-the-Wild Robustness: Demonstrates superior resilience on complex, non-standard layouts (FireRedBench) compared to traditional pipeline systems like PaddleOCR.

🏗️ Model Architecture

The FireRed-OCR framework transforms a general VLM into a structural expert through a three-stage progressive training strategy:

1. Stage 1: Multi-task Pre-alignment: Trains the model on detection, region recognition, and layout-to-markdown tasks to ground visual perception.
2. Stage 2: Specialized SFT: Fine-tunes on a high-quality, standardized Markdown dataset to ensure logical consistency and hierarchical expression.
3. Stage 3: Format-Constrained GRPO: Applies Reinforcement Learning with specific rewards for Formula Syntax, Table Integrity, Hierarchical Closure, and Text Accuracy.

⚡️ Quick Start

FireRed-OCR is based on the Qwen3-VL architecture. You can use the following code snippets to generate structured Markdown from document images.

1. Install Dependencies

pip install transformers
pip install qwen-vl-utils
git clone https://github.com/FireRedTeam/FireRed-OCR.git
cd FireRed-OCR

2. Inference

from transformers import Qwen3VLForConditionalGeneration, AutoProcessor
from conv_for_infer import generate_conv

# Load the model
model = Qwen3VLForConditionalGeneration.from_pretrained(
    "FireRedTeam/FireRed-OCR",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

# We recommend enabling flash_attention_2 for better acceleration and memory saving, especially in multi-image and video scenarios.
# model = Qwen3VLForConditionalGeneration.from_pretrained(
#     "FireRedTeam/FireRed-OCR,
#     dtype=torch.bfloat16,
#     attn_implementation="flash_attention_2",
#     device_map="auto",
# )

processor = AutoProcessor.from_pretrained("FireRedTeam/FireRed-OCR")

# Prepare Input
image_path = "./examples/complex_table.png"
messages = generate_conv(image_path)

# Preparation for inference
inputs = processor.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt"
)
inputs = inputs.to(model.device)

# Inference: Generation of the output
generated_ids = model.generate(**inputs, max_new_tokens=8192)
generated_ids_trimmed = [
    out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
