- AI model
- The part that reads, reasons, and writes. Claude, Gemini, Grok, and GPT are model families. Different models are better at different work, and they can have different costs and data terms.
- AI app
- The app around the model. People sometimes call this a workbench or harness. It is more than a chatbot because it can keep the conversation, files, instructions, tools, plans, and progress together for a long job. Codex, Claude Code and Desktop, OpenCode, Google Antigravity, Grok Build, Hermes Agent, OpenClaw, and Cursor are examples.
- The standard connection: MCP
- MCP means Model Context Protocol. Think of it as a common connection point. It lets an AI app find and use AgentZ without every AI company needing a different custom link.
- AI on your own equipment
- The technical term is local inference. The AI model runs on equipment controlled by the organisation instead of using a public online model service. This can suit some privacy or cost needs, but it still needs access rules, testing, and human review.
