An open-weight language models trained parameters or weights are publicly accessible, which can be used by developers to analyse and fine-tune the model for specific tasks without requiring original training data.
One of the things that is unique about open models is that people can run them locally. People can run them behind their own firewall, on their own infrastructure, OpenAI co-founder Greg Brockman said in a press briefing.
Open-weight language models are different from open-source models, which provide access to the complete source code, training data and methodologies.
Separately, Amazon announced OpenAIs open-weight models are now available on its Bedrock generative AI marketplace in Amazon Web Services. It marks the first time an OpenAI model has been offered on Bedrock, said Atul Deo, Bedrocks director of product.
OpenAI has been developing great models and we believe that these models are going to be great open-source options, or open-weight model options for customers, said Deo, in an interview. He declined to discuss any contractual arrangements between AWS and OpenAI.
