# 🕊️ Duchifat-2.2-Instruct

**Duchifat-2.2-Instruct** is a fine-tuned version of the original **Duchifat-2 base model**. While this specific version is an optimized Instruct/Chat model, the underlying base architecture and weights were developed and trained from scratch by **Raziel**.

## 🚀 Lineage & Development
- **Base Model (Duchifat-2):** Built and pre-trained from scratch on **3.27 Billion tokens** (50/50 Hebrew-English C4 dataset). It features 136M parameters and was designed to establish a native Hebrew reasoning foundation.
- **Version 2.2 (Instruct):** A refined fine-tuned version (SFT) designed to transform the base capabilities into a quirky, safe, and highly responsive conversational agent.

### Key Features:
* **Native Hebrew Foundation:** Unlike models that adapt English weights, Duchifat was born in Hebrew using the **DictaLM tokenizer**, ensuring high efficiency and natural linguistic flow.
* **Compact Power:** At only 136M parameters, it delivers impressive performance while remaining small enough for edge deployment and low-latency applications.
* **Quirky & Human-like:** The SFT process focused on giving the model a distinct personality—witty and engaging rather than robotic.
* **Safety Integrated:** Built-in guardrails ensure the model remains professional and refuses to engage with profanity or offensive prompts.

## 📊 Benchmark Results (Zero-Shot)
Tested using manual prompt formatting to accurately reflect real-world chat performance.

## 🛠️ Technical Specifications
* **Parameters:** 136M
* **Base Pre-training Data:** 3.27B tokens (C4 Hebrew/English)
* **Tokenizer:** DictaLM (Hebrew optimized)
* **Context Window:** 1024 tokens

## 💡 How to Use
Use the following instruction format to trigger the Instruct-tuned behavior:

Prompt Template:
```
<|instruction|>
{user_query}
<|assistant|>
```

## Example Usage:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "razielAI/Duchifat-2.2-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True).to("cuda")

prompt = "<|instruction|>\nשלום!\n<|assistant|>\n"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

output = model.generate(**inputs, max_new_tokens=256, temperature=0.7, do_sample=True)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```

## ⚠️ Limitations
Duchifat-2.2 is a lightweight model. It excels at conversational tasks, social media content, and short-form text generation. It is not designed for complex mathematical proofs or extensive coding sessions.
