This model is randomly initialized, using the config from [state-spaces/mamba-2.8b-hf](https://huggingface.co/state-spaces/mamba-2.8b-hf/blob/main/config.json) but with smaller size.

Codes:
```python
import os

import torch

import transformers
from huggingface_hub import create_repo, upload_folder

source_model_id = 'state-spaces/mamba-2.8b-hf'
tiny_random_name = 'mamba-tiny-random'
save_path = f'/tmp/yujiepan/{tiny_random_name}'
repo_id = f'yujiepan/{tiny_random_name}'

    source_model_id, trust_remote_code=True)
config.hidden_size = 8
config.expand = 4
config.intermediate_size = 32

config.num_hidden_layers = 2
config.n_layer = 2
config.torch_dtype = torch.bfloat16

model = transformers.AutoModelForCausalLM.from_config(

    trust_remote_code=True,
)
model.generation_config = transformers.GenerationConfig.from_pretrained(

    for name, p in sorted(model.named_parameters()):
        print(name, p.shape)
        torch.nn.init.uniform_(p, -0.5, 0.5)

model.save_pretrained(save_path)
