Jensen Huang’s first personal tweet supports open-source AI models NVIDIA CEO Jensen Huang posted his first-ever personal tweet, sharing an open letter co-signed by NVIDIA. The letter emphasizes the importance of 'open-weight models' for maintaining America’s leadership in AI. The letter states that the world needs both closed-source frontier models and open frontier models. Open weights can lower barriers to entry, enhance competition, and give users greater autonomy. It also specifically defends the legitimacy of 'distillation' technology—distillation involves using the output of one model to train or improve another model. It’s a widely used and legitimate technical method, and the letter urges policymakers not to confuse lawful development with theft. Co-signers of the letter include over 20 companies and organizations such as Andreessen Horowitz, Meta, Microsoft, Hugging Face, IBM, and Palantir.
