OpenAI on Aug. 5 released two open-weight language models, the company’s first such release since GPT-2 in 2019.
Open-weight models make their training parameters, or weights, publicly available but tend not to provide access to the source code or datasets. Open-source models typically include access to the source code, weights, and methodologies.
With weights publicly accessible, developers can analyze and fine-tune a model for specific tasks without requiring original training data.
The weights for the new gpt-oss-120b and gpt-oss-20b models are free to download for developers to fine-tune and deploy in their own environments, OpenAI said.
“These open models also lower barriers for emerging markets, resource-constrained sectors, and smaller organizations that may lack the budget or flexibility to adopt proprietary models,” OpenAI said in an Aug. 5 statement. “Broad access to these capable open-weights models created in the US helps expand democratic AI rails.”…
