## Model Details |
|
|
|
Arctic is a dense-MoE Hybrid transformer architecture pre-trained from scratch by the Snowflake AI |
|
Research Team. We are releasing model checkpoints for both the base and instruct-tuned versions of |
|
Arctic under an Apache-2.0 license. This means you can use them freely in your own research, |
|
prototypes, and products. Please see our blog |
|
[Snowflake Arctic: The Best LLM for Enterprise AI — Efficiently Intelligent, Truly Open](https://www.snowflake.com/blog/arctic-open-and-efficient-foundation-language-models-snowflake) |
|
for more information on Arctic and links to other relevant resources such as our series of cookbooks |
|
covering topics around training your own custom MoE models, how to produce high-quality training data, |
|
and much more. |

## Model Architecture |
|
|
|
Arctic combines a 10B dense transformer model with a residual 128x3.66B MoE MLP resulting in 480B |
|
total and 17B active parameters chosen using a top-2 gating. For more details about Arctic's model |
|
Architecture, training process, data, etc. [see our series of cookbooks](https://www.snowflake.com/en/data-cloud/arctic/cookbook/). |

## Usage |
|
|
|
As of 4/24/2024 we are actively working with the maintainers of `transformers` to include the Arctic |
|
model implementation. Until this support is released please follow these instructions to get the |
|
required dependencies for using Arctic: |
|
|
|
```python |
|
pip install git+https://github.com/Snowflake-Labs/transformers.git@arctic |
|
``` |
|
|
|
Arctic leverages several features from [DeepSpeed](https://github.com/microsoft/DeepSpeed), you will need to |
|
install the latest version of DeepSpeed to get all of these required features: |
|
|
|
```python |
|
pip install "deepspeed>=0.14.2" |
|
``` |
|
|
|
### Inference |
|
|
|
The Arctic github page has several resources around running inference: |
|
|
|
* Example with pure-HF: https://github.com/Snowflake-Labs/snowflake-arctic/blob/main/inference |
|
* Tutorial using vLLM: https://github.com/Snowflake-Labs/snowflake-arctic/tree/main/inference/vllm |
