# Tri-7B

## Introduction

We introduce **Tri-7B**, the next generation model following Trillion-7B-preview, that continues to push the boundaries of efficient training while achieving exceptional performance at the 7B parameter scale.

</p>


### Key Highlights
* **Enhanced Reasoning**: Modified training dataset mixture specifically optimized for reasoning capabilities
* **Advanced Post-Training**: Significantly improved RL training pipeline focusing on mathematical reasoning and everyday usage
* **Extended Context**: Supports up to 32K context length for long-form understanding
* **Multi-lingual**: Specially optimized for Korean, English, and Japanese.

Our **Tri-7B** model represents a significant advancement over Trillion-7B-preview, achieving substantial performance improvements across all evaluated domains while maintaining the same efficient parameter count.

### Model Specifications

## Quickstart

Here is a code snippet with `apply_chat_template` that demonstrates how to load the tokenizer and model and generate text.

### Tri-7B Usage
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "trillionlabs/Tri-7B"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Explain the concept of quantum computing in simple terms."
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```

Tri-7B is also available with vLLM and SGLang!

```bash
# vLLM
vllm serve trillionlabs/Tri-7B --dtype bfloat16 --max-model-len 32768

# vLLM with custom options
vllm serve trillionlabs/Tri-7B \
    --dtype bfloat16 \
    --max-model-len 32768 \
    --gpu-memory-utilization 0.95 \
    --port 8000
```

```bash
# SGLang
python3 -m sglang.launch_server --model-path trillionlabs/Tri-7B --dtype bfloat16

# SGLang with custom options
python3 -m sglang.launch_server \
    --model-path trillionlabs/Tri-7B \
    --dtype bfloat16 \
    --context-length 32768 \
    --port 30000 \
    --host 0.0.0.0
```

## Evaluation

We evaluated Tri-7B across a comprehensive suite of benchmarks assessing general reasoning, knowledge recall, coding abilities, mathematical reasoning, and instruction-following capabilities. Compared to our previous generation model Trillion-7B-preview, Tri-7B achieves significant gains across all domains.
