StableLM-Tuned-Alpha

Model Description

StableLM-Tuned-Alpha is a suite of 3B and 7B parameter decoder-only language models built on top of the StableLM-Base-Alpha models and further fine-tuned on various chat and instruction-following datasets.

Usage

Get started chatting with StableLM-Tuned-Alpha by using the following code snippet:

from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("StabilityAI/stablelm-tuned-alpha-7b")
model = AutoModelForCausalLM.from_pretrained("StabilityAI/stablelm-tuned-alpha-7b")
model.half().cuda()

inputs = tokenizer("What's your mood today?", return_tensors="pt").to('cuda')
tokens = model.generate(
  **inputs,
  max_new_tokens=64,
  temperature=0.7,
  do_sample=True,
)
print(tokenizer.decode(tokens[0], skip_special_tokens=True))

Training

Parameters	Hidden Size	Layers	Heads	Sequence Length
3B	4096	16	32	4096
7B	6144	16	48	4096

Training Dataset

StableLM-Tuned-Alpha models are fine-tuned on a combination of five datasets: Alpaca, a dataset of 52,000 instructions and demonstrations generated by OpenAI's text-davinci-003 engine. GPT4All Prompt Generations, which consists of 400k prompts and responses generated by GPT-4; Anthropic HH, made up of preferences about AI assistant helpfulness and harmlessness; DataBricks Dolly, comprising 15k instruction/responses generated by Databricks employees in capability domains from the InstructGPT paper, including brainstorming, classification, closed QA, generation, information extraction, open QA and summarization; and ShareGPT Vicuna (English subset), a dataset of conversations retrieved from ShareGPT.

Training Procedure

Models are learned via supervised fine-tuning on the aforementioned datasets, trained in mixed-precision (FP16), and optimized with AdamW. We outline the following hyperparameters:

Parameters	Batch Size	Learning Rate	Warm-up	Weight Decay	Betas
3B	256	2e-5	50	0.01	(0.9, 0.99)
7B	128	2e-5	100	0.01	(0.9, 0.99)

Use and Limitations

Intended Use

These models are intended to be used by the open-source community chat-like applications in adherence with the CC BY-NC-SA-4.0 license.

Limitations and bias

Although the aforementioned datasets help to steer the base language models into "safer" distributions of text, not all biases and toxicity can be mitigated through fine-tuning. We ask that users be mindful of such potential issues that can arise in generated responses. Do not treat model outputs as substitutes for human judgment or as sources of truth. Please use responsibly.
