A slew of new open-weight artificial intelligence models from American and European companies aim to convert users of Chinese open models who are concerned about security, but fall short of the dominant Chinese systems on performance despite having greater resources, experts said at a Rest of World event in San Francisco.

Last week, American startup Reflection launched its first open-weight model, and European labs Aleph Alpha and Mistral also released new open-weight models. Open models such as these offer users greater customization and control than the closed models of OpenAI, Anthropic, and Google at significantly lower costs.

For businesses and governments in lower-income countries, in particular, cost is the primary factor, as well as the expertise needed to customize open models for their specific needs, including in areas such as education, healthcare, and farming, Daniel Björkegren, an assistant professor at Columbia University, said at the Rest of World event last week.

American models are also very tuned for American workloads, but when you take those same models and try to deploy them in remote parts of the world, often they don’t work so well.”Daniel Björkegren, assistant professor at Columbia University
