Multi-agent is an AI architecture where multiple AI agents work together on a task, each with specialised roles. Tech jargon. Not concerning. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.
multi-agent
An architecture where multiple specialized AI agents coordinate — one plans, one executes, one reviews — instead of a single mega-agent doing everything.

An architecture where multiple specialized AI agents coordinate — one plans, one executes, one reviews — instead of a single mega-agent doing everything. The 2025 frontier.
"Rewrote the pipeline as a multi-agent system: a planner, an executor, and a judge."
Origin: Tech / AI / developer industry term.
For parents
Multi-agent is an AI architecture where multiple AI agents work together on a task, each with specialised roles. Tech jargon. Not concerning. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.
For ESL learners
Multi-agent is an AI-systems term describing architectures involving multiple cooperating or competing AI agents, often with specialised roles. Use in AI engineering and research writing. Formal equivalent: "multi-agent system." Common non-native mistake: hyphenation. "Multi-agent" (hyphenated) as an adjective is standard. Often appears in "multi-agent system" or "multi-agent workflow." Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

Semantically related
- agentic71%
Describing AI systems that can plan, take actions, and use tools autonomously across multi-step tasks — not just answer one prompt. The defining tech buzzword of 2025. Every vendor calls themselves agentic; half deliver a single tool call in a loop.
- agentic69%
Adjective for AI systems that act in multi-step loops rather than single-shot question-answer. An agentic system plans, takes actions, observes results, and replans. The 2024-2026 frontier of LLM productisation.
- A2A67%
Agent-to-Agent. Protocols for AI agents to communicate with each other autonomously — emerging as the multi-agent era becomes real in 2025. "A2A lets our planner agent hand off work to the research agent without human glue." Adjacent to MCP; specifically about peer-to-peer not client-server.
- copilot60%
An AI assistant embedded in a tool you already use — GitHub Copilot in your IDE, Microsoft Copilot in Office. The assistive, non-agentic cousin of modern AI agents.
- mid agentic60%
Mid agentic describes someone or something that shows up with autonomous initiative but only halfway — they take ownership of tasks unprompted, but the execution stalls before the finish line. The initiative is there, the follow-through isn't. A mid agentic AI tool starts workflows on its own but requires constant correction. A mid agentic coworker identifies problems without being asked but never quite closes the loop. It's the disappointment of watching promising autonomous energy fizzle into incomplete action: agentic enough to raise expectations, mid enough to not meet them.
