Summary
OpenAI has introduced gpt-oss, a new family of open language models, which unlike previous models, are released under the Apache 2.0 license. The two models, gpt-oss-120b and gpt-oss-20b, are innovative and capable, designed to be efficient and optimized for intelligence rather than sheer performance. They can be downloaded and fine-tuned for various purposes and highlight a shift back to openness in AI research. The implications of their structure and capabilities could influence future AI model development worldwide.
