Duchifat-2-Instruct

🚀 Duchifat-V2-Instruct (דוכיפת 2) | Official Model Card

📝 Executive Summary

Duchifat-V2-Instruct is a fine-tuned, instruction-following version of the Duchifat-V2 architecture (136M parameters). Developed by TopAI, this model is specifically optimized for creative content generation, bilingual dialogue, and task-oriented text processing.

While the base model provides a massive knowledge foundation from 3.27 billion tokens, the Instruct version has undergone targeted fine-tuning to transform it from a "text completer" into a creative writer capable of following complex prompts with a unique, human-like voice.

🎨 Model Capabilities & "The Creative Writer"

Unlike standard small-scale models, Duchifat-V2-Instruct exhibits "Creative Personality." It excels at:

• Narrative Writing: Crafting stories and monologues with emotional depth.
• Instruction Following: Responding to specific system prompts and user constraints.
• Bilingual Versatility: Seamlessly switching between Hebrew and English based on the prompt's linguistic context.
• Marketing & Copywriting: Generating slogans, blog posts, and creative ads.

Note: Due to its training on the C4 corpus, the model retains a vast "general knowledge" base, allowing it to act as a sophisticated creative partner rather than a purely technical agent.

📊 Training Infrastructure

• Dataset: Curated C4 (3.27B Tokens) - 50% Hebrew, 50% English.
• Fine-Tuning: Instruction-tuning on high-quality conversational and creative datasets.
• Optimization: AdamW with a focus on preserving the pre-trained knowledge (Knowledge Retention).

💻 Implementation & Inference

To utilize the Instruct capabilities, use the following structure:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

MODEL_ID = "TopAI-1/Duchifat-2-Instruct"

def run_duchifat_chat():
    print("--- Loading Duchifat-2 (Post 5-Epoch Instruct Training) ---")
    
    tokenizer = AutoTokenizer.from_pretrained(MODEL_ID, trust_remote_code=True)
    model = AutoModelForCausalLM.from_pretrained(

        trust_remote_code=True, 
        torch_dtype=torch.bfloat16,
        device_map="auto"
    )
    model.eval()
    model.config.use_cache = False 

    chat_history = []
    
    print("--- Model Ready! ---")

            full_prompt = "\n".join(chat_history) + "\nContent:"
            inputs = tokenizer(full_prompt, return_tensors="pt").to(model.device)

            )
        
        full_text = tokenizer.decode(output_tokens[0], skip_special_tokens=True)
        
        # Extract only the latest response
        parts = full_text.split("Content:")
