🌟 Model Description

This is a fine-tuned version of Qwen/Qwen2.5-7B-Instruct specifically optimized for Sanskrit language processing. The model has been trained using LoRA (Low-Rank Adaptation) on a comprehensive Sanskrit dataset to excel in three key areas:

Sanskrit to IAST Transliteration - Converting Devanagari script to IAST format
Sanskrit to English Translation - Translating Sanskrit text to English
English to Sanskrit Translation - Translating English text to Sanskrit

🚀 Key Features

IAST Transliteration: Accurate conversion from Devanagari to IAST
Bidirectional Translation: Sanskrit ↔ English translation
Context-Aware: Preserves meaning and cultural context
Chat-Optimized: Uses conversation format for natural interactions

🔧 Technical Improvements Over Previous Model

Enhanced Base Model: Upgraded from Qwen2.5-7B-Instruct-1M to Qwen2.5-7B-Instruct
Specialized Dataset: Trained on Sanskrit-transliteration-chat-dataset (vs. previous Sanskrit-llama)
Chat Template Format: Uses structured conversation format for better performance
Optimized LoRA: Improved LoRA configuration with better target modules
Memory Efficient: Enhanced with flash attention and gradient checkpointing

🛠️ Usage Examples

1. Sanskrit to IAST Transliteration

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "diabolic6045/Sanskrit-qwen-7B-Translate-v2"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Prepare the conversation
messages = [
    {
        "role": "system", 
        "content": "You are a Sanskrit transliteration expert. Convert the given Sanskrit text from Devanagari script to IAST (International Alphabet of Sanskrit Transliteration) format."
    },
    {
        "role": "user", 
        "content": "Transliterate this Sanskrit text to IAST: बुद्धिश्चार्थात्परो लोभः सन्तोषः परमं सुखम् ।"
    }
]

# Apply chat template and generate
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100, temperature=0.7)
response = tokenizer.decode(outputs[0][len(inputs.input_ids[0]):], skip_special_tokens=True)

print(response)
# Output: buddhiścārthātparo lobhaḥ santoṣaḥ paramaṃ sukham |

2. Sanskrit to English Translation

messages = [
    {
        "role": "system", 
        "content": "You are a Sanskrit to English translation expert. Translate the given Sanskrit text accurately while preserving the meaning and context."
    },
    {
        "role": "user", 
        "content": "Translate this Sanskrit text to English: यद॒ग्नौ सूर्ये॑ वि॒षं पृ॑थि॒व्यामोष॑धीषु॒ यत् ।"
    }
]

# Generate translation
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=150, temperature=0.7)
response = tokenizer.decode(outputs[0][len(inputs.input_ids[0]):], skip_special_tokens=True)

print(response)
# Output: The poison that is in the sun, in the earth and in the herbs...

3. English to Sanskrit Translation

messages = [
    {
        "role": "system", 
        "content": "You are an English to Sanskrit translation expert. Translate the given English text accurately into Sanskrit while preserving the meaning and context."
    },
    {
        "role": "user", 
        "content": "Translate this English text to Sanskrit: May the divine powers protect us and grant us wisdom."
    }
]

# Generate Sanskrit translation
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=200, temperature=0.7)
response = tokenizer.decode(outputs[0][len(inputs.input_ids[0]):], skip_special_tokens=True)

print(response)
# Output: देवाः अस्मान् रक्षन्तु बुद्धिं च प्रयच्छन्तु ।
