Internet reports that OpenAI has released two open weighting language models called GPT-OSS-120B and GPT-OSS-20B. These two models are designed to provide developers and researchers with lower-cost, easy-to-use options. OpenAI said it conducted extensive security training and testing on both models. The so-called "open weight" model means that its parameters are open to the public. Such models can provide greater transparency and controllability, but are different from "open source models", which open the entire source code and allow users to use and modify it freely.
