### Model Summary:

Llama-3.1-Centaur-70B is a foundation model of cognition model that can predict and simulate human behavior in any behavioral experiment expressed in natural language.

### Usage:

Note that Centaur is trained on a data set in which human choices are encapsulated by "<<" and ">>" tokens. For optimal performance, it is recommended to adjust prompts accordingly.

The recommended usage is by loading the low-rank adapter using unsloth:

```python
from unsloth import FastLanguageModel

model_name = "marcelbinz/Llama-3.1-Centaur-70B-adapter"
model, tokenizer = FastLanguageModel.from_pretrained(
  model_name = model_name,
  max_seq_length = 32768,
  dtype = None,
  load_in_4bit = True,
)

FastLanguageModel.for_inference(model)
```

This requires 80 GB GPU memory.

You can alternatively also directly use the less-tested [merged model](https://huggingface.co/marcelbinz/Llama-3.1-Centaur-70B).
