OpenAI, Anthropic, and Block have cofounded a new open source organization—the Agentic AI Foundation—to promote standards for artificial intelligence agents.
The three companies are also transferring ownership of some widely used agentic technologies over to the foundation. This includes Anthropic’s Model Context Protocol (MCP), which allows agents to connect and interact; OpenAI’s Agents.md, which lets programs and websites specify rules for coding agents; and Goose, a framework for building agents developed by Block. These technologies were already free to use, but through the new foundation it will be possible for others to contribute to their development.
“MCP is used by many companies, but there are others [who don’t use it],” says Nick Cooper, who leads work on the protocol at OpenAI. Cooper says that making MCP an open standard should encourage developers and companies to embrace it and build systems that integrate agentic AI. “That open interoperability—that open standard—really means that companies can talk across providers, and across agentic systems.”
The Agentic AI Foundation is being created under the Linux Foundation, which oversees development of the widely used open source Linux operating system as well as other projects. The foundation provides legal and technological support for the creation of open source foundations. Other companies who have signed on to the AAIF, beyond the three founding members, include Google, Microsoft, AWS, Bloomberg, and Cloudflare.
The new foundation reflects a nascent shift from chat-based AI systems to greater use of programs that take actions on behalf of users. This kind of agentic AI promises a potentially lucrative new paradigm in which AI agents use the web and negotiate with one another to power all sorts of applications. Consumers may, for example, use AI assistants to buy and book things, while businesses use AI agents to manage transactions and customer interactions.
Srinivas Narayanan, chief technology officer of B2B applications at OpenAI, envisions a time when large numbers of AI agents routinely communicate with one another in the course of business. The AI industry working across the same open standards should help ensure that those interactions happen seamlessly. “Open source is going to play a very big role in how AI is shaped and adopted in the real world,” Narayanan says.
The question of openness seems crucial to AI right now. US companies mostly make money by offering access to powerful closed models through application programming interfaces, or APIs. Meta previously released the weights for its best model, Llama, so that anyone could download and run it, although the company has recently signaled a shift to a more closed approach. A number of Chinese AI companies, including DeepSeek, Alibaba, Moonshot AI, and Z.ai, provide strong open source models that have become popular with developers, startups, and AI researchers. Some worry that this picture could give Chinese firms a big strategic advantage over time.
