# DeepLatent Base Model

This is a DeepLatent model checkpoint from the base training stage.

## Model Details

- **Stage**: base
- **Model Tag**: deeplatent_200m
- **Step**: latest
- **Architecture**: DeepLatent (Continuous Thought Machine)

## Usage

```python
from models.DeepLatent.DeepLatent import DeepLatent
from models.DeepLatent.tokenizer import get_tokenizer

# Load model
model = DeepLatent.from_pretrained("almaghrabima/deeplatent-base")

# Load tokenizer
tokenizer = get_tokenizer()  # or load from the tokenizer directory in the repo

# Use model
inputs = tokenizer("Hello, world!")
outputs = model(inputs)
```
