OpenAI has released its first open-weight models in over five years, introducing gpt-oss-120b and gpt-oss-20b, designed for local operation on consumer devices and customizable for specific tasks. This marks a strategic shift for OpenAI from proprietary releases to more accessible AI models, aimed at making AI technology widely available. CEO Sam Altman emphasized that this initiative stems from extensive research investment. Users can download these models for free on Hugging Face, and unlike ChatGPT, they function without internet connectivity. Both models utilize chain-of-thought reasoning for enhanced responses and are licensed under Apache 2.0, enabling commercial use and redistribution. OpenAI has conducted thorough safety evaluations for these open models to prevent misuse. Despite potential risks associated with open-weight releases, tests indicate that the models remain within acceptable safety parameters. This release complements OpenAI’s proprietary services while expanding the AI toolkit for developers.
