Google, AMD, Cloudflare and other companies joined in, and the number of organizations signing the open letter supporting the development of AI open source models increased to 50

IT House reported on July 26 that 25 U.S. technology companies including Nvidia, Microsoft, IBM, and Meta signed an open letter this week (July 24) calling for the opening of weighted AI models. IT House has learned that the open letter uses the history of the open source software movement as a reference to discuss the key significance of open weighted AI models for the United States to seize the initiative in the artificial intelligence era. The open weight model can be downloaded, modified and deployed independently by all parties. It can lower the threshold for various institutions to use advanced AI, activate market competition, prevent AI revenue from being monopolized by a few companies, and at the same time allow users to gain technological autonomy and get rid of the binding of a single manufacturer. The open letter pointed out that although open weights have risks such as difficulty in controlling derivative versions, closed models also have security risks. An open ecosystem can mobilize researchers to investigate loopholes and improve security protection, which is an important path to realize artificial intelligence security. At present, the number of companies/organizations that have signed the open letter has reached 50. The newly joined companies include Google, AMD, Cloudflare, Block, and Ollama, as well as OpenAI, Y Combinator, GitHub, Cisco, etc. that have appeared in previous reports by IT House. It is worth noting that Amazon and Anthropic have not signed this statement so far, which has attracted attention from the outside world. Forbes believes that the reason for this is business interests, and Amazon is the largest investor in Anthropic. And Anthropic has only provided closed-source AI model services from beginning to end, and the company has always adhered to the "AI safety" stance.
