OpenAI has launched two open-weight models, gpt-oss-120b and gpt-oss-20b, after extensive safety testing. CEO Sam Altman stated, “We’re excited to make this model... available to the world.” These models, designed for versatile deployment from PCs to cloud services, can perform advanced reasoning and tool use. Users can access them on platforms like Hugging Face under an Apache 2.0 license. This move aims to enhance accessibility to AI technology amid growing competition in the industry.
