# AIDO.Protein-16B-v1
## Model Description
We pretrained our model in three stages. This model represents the final stage, where we continued training our AIDO.Protein-16B using an additional 100 billion amino acids from Uniref90.

## How to Use
### Build any downstream models from this backbone
#### Embedding
```python
from genbio_finetune.tasks import Embed
model = Embed.from_config({"model.backbone": "proteinfm_v1"}).eval()
collated_batch = model.collate({"sequences": ["ACGT", "AGCT"]})
embedding = model(collated_batch)
print(embedding.shape)
print(embedding)
```
#### Sequence Level Classification
```python
import torch
from genbio_finetune.tasks import SequenceClassification
model = SequenceClassification.from_config({"model.backbone": "proteinfm_v1", "model.n_classes": 2}).eval()
collated_batch = model.collate({"sequences": ["ACGT", "AGCT"]})
logits = model(collated_batch)
print(logits)
print(torch.argmax(logits, dim=-1))
```
#### Token Level Classification
```python
import torch
from genbio_finetune.tasks import TokenClassification
model = TokenClassification.from_config({"model.backbone": "proteinfm_v1", "model.n_classes": 3}).eval()
collated_batch = model.collate({"sequences": ["ACGT", "AGCT"]})
logits = model(collated_batch)
print(logits)
print(torch.argmax(logits, dim=-1))
```
#### Regression
```python
from genbio_finetune.tasks import SequenceRegression
model = SequenceRegression.from_config({"model.backbone": "proteinfm_v1"}).eval()
collated_batch = model.collate({"sequences": ["ACGT", "AGCT"]})
logits = model(collated_batch)
print(logits)
```
#### Protein-Protein Interaction
