# `Stable LM 2 1.6B` (global_step420000)
## Description
`Stable LM 2 1.6B` is a 1.6 billion parameter decoder-only language model pre-trained on 2 trillion tokens of diverse multilingual and code datasets for two epochs.
## Usage
This branch contains the training checkpoint for `Stable LM 2 1.6B` at step 420,000. It is the final checkpoint taken before cooldown.
We provide the following contents in the [`global_step420000`](https://huggingface.co/stabilityai/stablelm-2-1_6b/tree/global_step420000/global_step420000) directory:
- `bf16_zero_pp_mp_rank_00_optim_states.pt`: The Adam states and FP32 weights for each parameter. You will need to port this to your optimizer format when importing into your training process.
- `mp_rank_00_model_states.pt`: The model weights following the [GPT-NeoX](https://github.com/EleutherAI/gpt-neox) convention.
- `config.yml`: The pre-training configuration file for this checkpoint. Linear learning rate cooldown should be taken from `lr=0.0002529` to `lr=0.0`.
The model weights are also converted to HuggingFace `transformers` format and can be loaded with the following code:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("stabilityai/stablelm-2-1_6b", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
"stabilityai/stablelm-2-1_6b",
trust_remote_code=True,
torch_dtype="auto",
revision="global_step420000"
)
model.cuda()
```
