OPT-1.3b-Chat

This is a text generation model based on the OPT-1.3B model from Meta, trained using the Deepspeed library. The model can generate natural and engaging conversational responses given a user input.

A Demo is available here The model is best at simple Q&A style questions, not open-ended ones like ChatGPT.

Training Details

• The base model is OPT-1.3B, a decoder-only transformer with 1.3 billion parameters, pre-trained on a large text corpus using the causal language modeling objective.
• The model was trained on a single NVIDIA A100 GPU using the Deepspeed pipeline parallelism and ZeRO optimizer.

Model Details

• Number of parameters: 1.3 billion
• Number of layers: 24
• Number of attention heads: 16
• Context size: 2048
• Vocabulary size: 50,265
• Embedding size: 1280
• Feed-forward size: 5120
• Dropout rate: 0.1

Usage

You can use this model directly with the Hugging Face pipeline for text generation:

from transformers import pipeline
generator = pipeline('text-generation', model='DarwinAnim8or/OPT-1.3b-Chat')
generator("Hello, how are you?")

Suggested formatting

The training data uses the following format:

Human: <question>
Assistant: <answer>

It is recommended to follow the same format as closely as possible for the best results. We do intend on creating another model that is trained on the openassistant dataset in the future.
