**Auto-Completer-0.1** is a fine-tuned version of [SmolLM2-360M](https://huggingface.co/HuggingFaceTB/SmolLM2-360M), optimized for **long-range dependency modeling** and **state-of-the-art auto-completion performance**. Trained on an additional **4.2 million tokens** of curated instruction-style and math-rich data, this model excels at completing documents, code, and reasoning chains with high fidelity and semantic coherence.

---

## 🚀 Highlights

- 🔍 **Base Model**: SmolLM2-360M (360M parameters, instruction-tuned)
- 📈 **Fine-Tuning Tokens**: +4.2M tokens focused on long-context reasoning
- 🧠 **Specialization**: Auto-completion, document continuation, math reasoning
- 🧪 **Performance**: SOTA on internal benchmarks for completion accuracy and semantic retention
- 🧰 **Context Length**: Up to 4K tokens with packing enabled

### How to use

```bash
pip install transformers
```

## 🧪 Example Usage

>Don't try to use it as a chat model its not meant for that

* _Using full precision_
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

checkpoint = "Parveshiiii/Auto-Completer-0.1"
device = "cuda"  # or "cpu"

tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint).to(device)

inputs = tokenizer.encode("Gravity is", return_tensors="pt").to(device)

outputs = model.generate(
    inputs,
    repetition_penalty=1.2,                 # you can increase it as it can often stuck in loops after it autocompletes the sentence
    max_new_tokens=10,                      # as a autocomplete model i would suggest to use lower max token as the model generates till the max token cap
    do_sample=True,                         # use this  for diversity
    eos_token_id=tokenizer.eos_token_id     # Optional: stop at end-of-text
)

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

* _Using `torch.bfloat16`_
```python
# pip install accelerate
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

checkpoint = "Parveshiiii/Auto-Completer-0.1"
device = "cuda"

tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(
    checkpoint,
    device_map="auto",
    torch_dtype=torch.bfloat16  # or torch.float16 for fp16
)

# Encode prompt
inputs = tokenizer.encode("Gravity is", return_tensors="pt").to(device)

# Generate with sampling and token control
outputs = model.generate(
    inputs,
    max_new_tokens=10,         # as a autocomplete model i would suggest to use lower max token as the model generates till the max token cap
    do_sample=True,            # Enable sampling for diversity
    temperature=0.7,           # Controls randomness (lower = more deterministic)
    top_p=0.9,                 # Nucleus sampling (focus on top 90% of probability mass)
    repetition_penalty=1.2,    # you can increase it as it can often stuck in loops after it autocompletes the sentence
    eos_token_id=tokenizer.eos_token_id  # Optional: stop at end-of-text
)

# Decode and print
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
```bash
>>> print(f"Memory footprint: {model.get_memory_footprint() / 1e6:.2f} MB")
Memory footprint: 723.56 MB
```

## ⚠️ Limitations

- Not optimized for multi-turn chat
- May hallucinate in open-ended prompts without structure
- Limited factual grounding beyond training corpus
