6 companies in this category
Overview
Proprietary Models are the closed-source AI brains that power the most capable autonomous agents. Claude by Anthropic drives MCP-enabled agentic commerce with context retention across sessions.
GPT by OpenAI powers the Agentic Commerce Protocol with Stripe and Instant Checkout in ChatGPT. Gemini by Google powers Project Mariner, AP2, and UCP.
Grok by xAI offers frontier tool-calling with 2M-token context. Command by Cohere focuses on enterprise deployments with best-in-class tool-use accuracy in 23 languages.
Nova by Amazon provides native MCP support with Bedrock AgentCore for policy enforcement. The competitive dynamic is clear: each major model provider is building its own agentic commerce stack, and the model you choose increasingly determines which payment protocols and commerce ecosystems you plug into.
