library_name: transformers
base_model:
- tiiuae/Falcon-H1-34B-Instruct
---

This tiny model is intended for debugging. It is randomly initialized using the configuration adapted from [tiiuae/Falcon-H1-34B-Instruct](https://huggingface.co/tiiuae/Falcon-H1-34B-Instruct).

### Example usage:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_id = "yujiepan/falcon-h1-tiny-random"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
)
pipe = pipeline('text-generation', model=model,
                tokenizer=tokenizer, trust_remote_code=True)
print(pipe('Write an article about Artificial Intelligence.', max_new_tokens=32))
```

### Codes to create this repo:

```python

    )
set_seed(42)

with torch.no_grad():
    for name, p in sorted(model.named_parameters()):
