According to Andrew Ng on Twitter, OpenAI has released two open weight AI models, with initial tests indicating that gpt-oss-120b demonstrates strong performance. This move marks a significant step for AI developers and businesses seeking accessible, high-performance language models for commercial and research applications. OpenAI's open weight release is expected to foster innovation, lower barriers to entry for startups, and accelerate the adoption of generative AI solutions across industries. However, Andrew Ng cautions that rigorous third-party evaluations are still needed to fully validate these models' capabilities (source: Andrew Ng, Twitter, August 5, 2025).
