# Precis: Document Summarization

## Model Overview

**Precis** is a specialized document summarization model fine-tuned from IBM's Granite 4.0-H-Micro (3.2B parameters) using efficient LoRA adapters. It generates comprehensive ~300-word summaries optimized for question-answering capability while maintaining complete privacy through local, on-premise processing.

**Key Features:**
- 🔒 **Privacy-First**: Process sensitive documents entirely on your infrastructure
- ⚡ **Fast**: 0.5s inference time (5-10x faster than cloud APIs)
- 💰 **Cost-Effective**: Zero per-document API fees
- 📚 **Long Context**: 128K tokens ≈ 320-380 book pages
- 🎯 **Specialized**: Trained on 5,500+ document-summary pairs, processed millions of tokens during training


## 🚀 Quick Start

### Using with Transformers + PEFT

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "unsloth/granite-4.0-h-micro",
    torch_dtype=torch.float16,
    device_map="auto"
)

# Load LoRA adapters
model = PeftModel.from_pretrained(base_model, "cernis-intelligence/precis")
tokenizer = AutoTokenizer.from_pretrained("cernis-intelligence/precis")

# Generate summary
document = """Your long document here..."""

messages = [
    {"role": "user", "content": f"Summarize the following document in around 300 words:\n\n{document}"}
]

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

outputs = model.generate(
    inputs,
    max_new_tokens=512,
    temperature=0.3,
    top_p=0.9,
    do_sample=True
)

summary = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(summary)
```

### Using with Unsloth (Recommended)

```python
from unsloth import FastLanguageModel

model, tokenizer = FastLanguageModel.from_pretrained(
    model_name="cernis-intelligence/precis",
    max_seq_length=2048,
    load_in_4bit=True,  # For lower memory usage
)

FastLanguageModel.for_inference(model)

messages = [
    {"role": "user", "content": f"Summarize the following document in around 300 words:\n\n{document}"}
]

inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_tensors="pt"
).to("cuda")

outputs = model.generate(inputs, max_new_tokens=512, temperature=0.3)
summary = tokenizer.decode(outputs[0], skip_special_tokens=True)
```

### Using with vLLM (Production)

```python
from vllm import LLM, SamplingParams
from vllm.lora.request import LoRARequest

# Initialize vLLM with base model
llm = LLM(
    model="unsloth/granite-4.0-h-micro",
    enable_lora=True,
    max_lora_rank=32,
    gpu_memory_utilization=0.9
)

# Create LoRA request
lora_request = LoRARequest(
    "precis-granite",
    1,
    "cernis-intelligence/precis"
)

# Sampling parameters
sampling_params = SamplingParams(
    temperature=0.3,
    top_p=0.9,
    max_tokens=512
)

# Generate
prompts = ["Summarize the following document in around 300 words:\n\n" + document]
outputs = llm.generate(prompts, sampling_params, lora_request=lora_request)

print(outputs[0].outputs[0].text)
```

## 📊 Training Details

### Base Model
- **Architecture**: IBM Granite 4.0-H-Micro
- **Parameters**: 3.2B (38.4M trainable via LoRA)
- **Context Length**: 128K tokens
- **License**: Apache 2.0

## 🎯 Use Cases

### ✅ Perfect For:
- 📄 **Legal Document Review**: Summarize contracts while maintaining confidentiality
- 🏥 **Medical Records**: HIPAA-compliant summarization of patient notes
- 💼 **Financial Reports**: Analyze earnings reports without exposing sensitive data
- 📚 **Research Papers**: Quick digests of academic literature
- 📧 **Email Threads**: Comprehensive summaries of long conversations

### ⚠️ Considerations:
- Works best with documents under 380 pages (128K token limit)
- Optimized for English text (multilingual support coming)
- May miss some deeply nested structured data (tables, forms)
- For specialized needs, consider fine-tuning on domain-specific data
