## Introducing GenZ Infinite

The model is a finetuned version of Genz-13B-v2 with a context size of 16K. The model architecture is updated to have lamda attention from the LM-Infinite paper which gives the model capability of 120K+ sequence length without affecting the preplexity

## Generate responses

Use the generate.py file from the [github repo](https://github.com/BudEcosystem/genz-infinite)

```
python generate.py --base_model budecosystem/genz-13b-infinite

```

You can integrate the model in your code my loading convert_llama_model function.

```python
import torch
from transformers import GenerationConfig, AutoModelForCausalLM, AutoTokenizer
from model.llama import convert_llama_model

local_branch = 2048
global_branch = 10
limit_distance = 2048

model = AutoModelForCausalLM.from_pretrained(
    "budecosystem/genz-13b-infinite",
    torch_dtype=torch.float16,
    device_map="auto",
)
model = convert_llama_model(model, local_branch, global_branch)

```
