OpenAI Releases First Open Weighted AI Model Since 2019

Open weighting models can provide transparency and control, but they differ from open source models, which make the entire source code available for anyone to use and modify.

OpenAI on August 5 announced two open weighted language models for the first time since launching GPT-2 in 2019.

An artificial intelligence model is considered open weight if its parameters, i.e. the factors that help improve the output and predictions during training, are publicly available.

Open weighting models can provide transparency and control, but they differ from open source models, which make the entire source code available for anyone to use and modify.

OpenAI says these text-only models, called gpt-oss-120b and gpt-oss-20b, are designed to provide developers, researchers, and companies with lower-cost options that are easy to operate and customize.

Both of OpenAI's new models can handle advanced inference, tool use, and neural processing tasks. They're designed to run anywhere from consumer hardware to cloud platforms to on-device applications.

OpenAI says users can run gpt-oss-20b on a laptop and use it as a personal assistant that can search through files and write.

The company has partnered with Nvidia, Advanced Micro Devices (AMD), Cerebras, and Groq to ensure these models will work well on a variety of chips.

OpenAI's release of its open weighting models has been highly anticipated, in part because the company has repeatedly delayed the launch as it needs more time to conduct additional safety testing and review high-risk areas.

OpenAI said on August 5 that it had conducted extensive training and safety testing of its open weight models. The company filtered out harmful chemical, biological, radiological, and nuclear data during the pre-training phase and simulated how bad actors might try to fine-tune the models for malicious purposes.

OpenAI also said it worked with three independent groups of experts to get feedback on its assessment of this malicious tweaking process.

In recent years, several other tech companies, such as Meta, Microsoft-backed Mistral AI, and Chinese startup DeepSeek, have also released open weighting models./.
