Foundation model companies

This group brings together companies behind general AI assistants, coding products, and model families: OpenAI, Anthropic, Google DeepMind, Microsoft AI, Meta AI, Mistral AI, Cohere, xAI, and DeepSeek. Their products cover conversations, research, document work, and software development.

A company, a model, and an app are different things. Claude and Claude Code have different workflows; Meta AI and the Llama model family are separate products. Before changing tools, check which files, instructions, conversations, and connections belong to the app you currently use. Access to another model does not automatically move that work with it.

Questions people ask

Which foundation model companies are in this guide?

The group includes OpenAI, Anthropic, Google DeepMind, Microsoft AI, Meta AI, Mistral AI, Cohere, xAI, and DeepSeek. Each company entry identifies its products and links to the vendor source used for its description.

Is an AI assistant the same thing as a model?

A model and the product used to reach it are different things. An assistant app can add conversations, files, instructions, and tool connections around a model. A company's chat app, coding tool, and developer API may have different features and controls.

Does using another model transfer my existing chats?

Do not assume it does. For example, running a Llama model in another application does not transfer a Meta AI account or its chat history. Check the original product's export options and the destination product's supported inputs before moving work.
