The Snowflake Arctic model is a cutting-edge, hybrid transformer architecture that’s making waves in the AI community. Developed by the Snowflake AI Research Team, it’s now publicly available for you to harness in your applications. This guide will walk you through the key details of the Arctic model, its architecture, how to set it up, and troubleshoot common issues.

Model Details

The Snowflake Arctic model combines a dense-MoE transformer architecture pre-trained from scratch. It includes both base and instruct-tuned versions under the Apache-2.0 license, allowing for free use in research, prototypes, and products. You can explore more about the model on the blog Snowflake Arctic: The Best LLM for Enterprise AI — Efficiently Intelligent, Truly Open.

Understanding the Architecture

Picture the Arctic model like a highly efficient restaurant kitchen, where different types of chefs (parameters) are on standby, preparing food (output). The kitchen uses a combination of a main chef (10B dense transformer model) alongside specialized sous-chefs (128×3.66B MoE MLP) to whip up complex dishes efficiently. The top-2 gating mechanism ensures that only the best sous-chefs are summoned to handle specific tasks, leading to optimized and delicious outcomes (results).

Setup Instructions

To start using the Arctic model, follow these steps:

• Install the required transformers version:

python
pip install transformers==4.39.0

• Install DeepSpeed:

python
pip install deepspeed==0.14.2

After installation, you can easily load and use the Arctic model for inference.

Inference Example

Due to the model’s size, it’s recommended to utilize a powerful instance from your cloud provider, such as:

• AWS p5.48xlarge
• Azure ND96isr_H100_v5

Here’s a sample code snippet to get you started:

python
import os
os.environ['HF_HUB_ENABLE_HF_TRANSFER'] = '1'
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
from deepspeed.linear.config import QuantizationConfig

tokenizer = AutoTokenizer.from_pretrained('Snowflake/snowflake-arctic-instruct', trust_remote_code=True)

quant_config = QuantizationConfig(q_bits=8)

model = AutoModelForCausalLM.from_pretrained(
    'Snowflake/snowflake-arctic-instruct',
    trust_remote_code=True,
    low_cpu_mem_usage=True,
    device_map='auto',
    ds_quantization_config=quant_config,
    max_memory={i: '150GiB' for i in range(8)},
    torch_dtype=torch.bfloat16
)

content = "5x + 35 = 7x - 60 + 10. Solve for x"
messages = [{"role": "user", "content": content}]
input_ids = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors='pt').to('cuda')

outputs = model.generate(input_ids=input_ids, max_new_tokens=256)
print(tokenizer.decode(outputs[0]))

Troubleshooting

While using the Arctic model, you may run into occasional hiccups. Here are some troubleshooting tips to help you sail smoothly:

• Model Loading Issues: Ensure that your internet connection is stable and that your environment has sufficient memory allocated.
• Dependencies Errors: Double-check that you have the correct versions of transformers and DeepSpeed installed as shown above.
• Output Quality: Remember to experiment with quantization settings for optimal performance based on your specific requirements.
