🇮🇳 Gemma-4-E4B-Hindi-Instruct (16-bit)

A Hindi instruction-tuned fine-tune of Gemma 4 E4B. This is the merged 16-bit model for use with 🤗 Transformers / vLLM / further fine-tuning.

For local CPU/edge use, see the GGUF build.

Part of my Hindi LLM Series — small, openly-documented Indic models that actually follow instructions in Hindi and run on your own machine.

Usage (Transformers)

from transformers import AutoModelForCausalLM, AutoProcessor
import torch

model_id = "pankajpandey-dev/gemma-4-e4b-hindi-instruct"
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="auto")
proc  = AutoProcessor.from_pretrained(model_id)

msgs = [{"role": "user", "content": [{"type": "text", "text": "मशीन लर्निंग को आसान शब्दों में समझाओ।"}]}]
inputs = proc.apply_chat_template(msgs, add_generation_prompt=True, tokenize=True,
                                  return_dict=True, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=256, use_cache=True)
print(proc.decode(out[0], skip_special_tokens=True))

Example outputs

Prompt: भारत के बारे में एक रोचक तथ्य बताओ।

भारत दुनिया में सबसे अधिक भाषाओं वाले देशों में से एक है — 22 आधिकारिक भाषाएँ और 1,000 से अधिक बोलियाँ। हिंदी एक इंडो-आर्यन भाषा है, जबकि तमिल एक द्रविड़ भाषा है।

Training details

Trained text-only (vision layers frozen), single-BOS chat template to avoid double-BOS corruption.

Limitations

• ~8B-class model: strong Hindi fluency, but can hallucinate facts and occasionally repeat phrasing on long open-ended generation.
• Tuned for single-turn Hindi instructions; long multi-turn chat is not the focus.
• Not safety-aligned for production.
