🇮🇳 Bharat-Tiny-LLM v2 (PyTorch / Transformers Base)

1.5B Parameter Open-Weights Indic LLM featuring Brahmi Token Injection for 33.8% token compression and +36% faster Hindi inference.

🎯 Model Overview

Bharat-Tiny-LLM v2 is an open-weights 1.5B parameter language model built on top of Qwen2.5-1.5B, optimized specifically for Hindi and Hinglish text generation.

By introducing Brahmi Token Injection — a technique that surgically injects 300 Devanagari subword tokens into the model's vocabulary — Bharat-Tiny-LLM v2 eliminates the severe "Token Tax" imposed by standard English-centric tokenizers on Indian scripts.

This repository contains the unquantized PyTorch / HuggingFace Transformers open weights, compatible with Linux, Windows, CUDA GPUs, vLLM, TGI, and Google Colab.

🚀 Quick Start with PyTorch & Transformers

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "eulogik/Bharat-Tiny-LLM-v2"

# Load Tokenizer & Model Weights
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Generate Hindi Text
prompt = "भारत की सांस्कृतिक विविधता के बारे में बताइए:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=150,
    temperature=0.7,
    do_sample=True
)

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

📊 Token Compression Benchmarks

Prompt (Hindi / Hinglish)	Base Qwen Tokens	Bharat-v2 Tokens	Savings
`"ज़रूरी बात है क्या करते हो"`	26 tokens	11 tokens	58% Savings
`"नमस्ते, आप कैसे हैं?"`	15 tokens	7 tokens	53% Savings
`"भारत की राजधानी नई दिल्ली है"`	22 tokens	14 tokens	36% Savings
`"bhai aaj ka weather kaisa hai?"`	12 tokens	8 tokens	33% Savings
