## Evo 2

Evo 2 is a state-of-the-art DNA language model trained autoregressively on trillions of DNA tokens.

For instructions, details, and examples, please refer to the [github](https://github.com/ArcInstitute/evo2) and [paper]().

Evo 2 40B and 7B checkpoints, trained up to 1 million sequence length, are available here:
| Checkpoint name | Num layers | Num parameters |
|------------------------------|----|----------|
| [evo2_40b](https://huggingface.co/arcinstitute/evo2_40b) | 50 | 40B |
| [evo2_7b](https://huggingface.co/arcinstitute/evo2_7b) | 32 | 7B  | 

We also share 40B, 7B, and 1B base checkpoints trained on 8192 context length:
| Checkpoint name | Num layers | Num parameters |
|------------------------------|----|----------|
| [evo2_40b_base](https://huggingface.co/arcinstitute/evo2_40b_base) | 50 | 40B |
| [evo2_7b_base](https://huggingface.co/arcinstitute/evo2_7b_base) | 32 | 7B  | 
| [evo2_1b_base](https://huggingface.co/arcinstitute/evo2_1b_base) | 25 | 1B  |
