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.

💡 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.
