📊 Performance

Metric	Original	Optimized
Parameters	1.1B	1.1B (4.3% pruned)
Disk	2.7GB	1.3GB (52%↓)
GPU	3.5GB+	2.3GB
Speed	1x	2-3x

🚀 Quickstart

python

from transformers import BitsAndBytesConfig, AutoProcessor, AutoModelForImageTextToText
import torch

MODEL_PATH = "ManiKumarAdapala/glm-ocr-pruned-8bit"

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "url": "Image.jpeg"
            },
            {
                "type": "text",
                "text": "Text Recognition:"
            }
        ],
    }
]

quant_config = BitsAndBytesConfig(load_in_8bit=True)

processor = AutoProcessor.from_pretrained(MODEL_PATH)
model = AutoModelForImageTextToText.from_pretrained(
    pretrained_model_name_or_path=MODEL_PATH,
    quantization_config=quant_config,
    device_map="auto",
)

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

inputs.pop("token_type_ids", None)

generated_ids = model.generate(**inputs, max_new_tokens=8192)

output_text = processor.decode(generated_ids[0][inputs["input_ids"].shape[1]:], skip_special_tokens=False)

print(output_text)

🛠 Optimizations Applied

✅ Selective Pruning: q_proj, v_proj, fc2, vision_tower (52%)
✅ BitsAndBytes 8-bit: Linear8bitLt (vision+text decoder)
✅ Protected: lm_head, early vision, final decoder layers
