# MAMBA (2.8B) 🐍 fine-tuned on OpenHerms

Model Card is still WIP!


## Base model info

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers.
It is based on the line of progress on [structured state space models](https://github.com/state-spaces/s4),
with an efficient hardware-aware design and implementation in the spirit of [FlashAttention](https://github.com/Dao-AILab/flash-attention).

## Dataset info

TBA


## Usage

```sh
pip install transformers
pip install causal-conv1d<=1.0.2
pip install mamba-ssm
```

```py
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
from mamba_ssm.models.mixer_seq_simple import MambaLMHeadModel

CHAT_TEMPLATE_ID = "HuggingFaceH4/zephyr-7b-beta"

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model_name = "clibrain/mamba-2.8b-instruct-openhermes"

eos_token = "<|endoftext|>"
tokenizer = AutoTokenizer.from_pretrained(model_name)
tokenizer.eos_token = eos_token
tokenizer.pad_token = tokenizer.eos_token
tokenizer.chat_template = AutoTokenizer.from_pretrained(CHAT_TEMPLATE_ID).chat_template

model = MambaLMHeadModel.from_pretrained(
        model_name, device=device, dtype=torch.float16)

history_dict: list[dict[str, str]] = []
prompt = "Tell me 5 sites to visit in Spain"
history_dict.append(dict(role="user", content=prompt))

input_ids = tokenizer.apply_chat_template(
            history_dict, return_tensors="pt", add_generation_prompt=True
).to(device)

out = model.generate(
    input_ids=input_ids,
    max_length=2000,
    temperature=0.9,
    top_p=0.7,
    eos_token_id=tokenizer.eos_token_id,
)

decoded = tokenizer.batch_decode(out)
assistant_message = (
    decoded[0].split("<|assistant|>\n")[-1].replace(eos, "")
)

print(assistant_message)
```


## Gradio Demo

```sh
git clone https://github.com/mrm8488/mamba-chat.git
cd mamba-chat

pip install -r requirements.txt
pip install -q gradio==4.8.0

python app.py \
--model clibrain/mamba-2.8b-chat-no_robots \
--share
```
## Evaluations

Coming soon!
