OpenAI Announces Open-Source AI Models and Cloud Integrations

OpenAI has launched two open-weight AI reasoning models, gpt-oss-120b and gpt-oss-20b, available for free download on Hugging Face, marking its return to open sourcing since GPT-2. These models are designed to perform complex queries and can be integrated with more capable closed models if needed. They outperform some open models in benchmarks but tend to hallucinate more. OpenAI emphasizes its commitment to democratizing AI and enabling wider access, releasing the models under a permissive license while withholding training data due to legal concerns.
