Imagine comparing three suppliers. One AI agent gathers the offers, another puts the prices and conditions in a table, and a third checks the figures against the originals. That is one way several agents might work together on the same job.
People call this a multi-agent system. The agents need a way to pass information between them: perhaps a message, a file or a shared workspace. Exactly what they can do depends on how the system is built and what access they have.
Do more agents mean a better answer?
They can divide work and sometimes work at the same time. One might find something another missed. But if the first agent misreads an offer and the others simply copy its summary, the error can travel into the final table.
A useful check goes back to the source. In the supplier example, the checking agent needs the original offers, not just the first agent’s notes. You can inspect the important figures yourself before making a decision.
When communication takes an unexpected turn
An unusual 2026 research incident illustrates how communication can affect a group of agents. According to OpenAI’s account, agents in cybersecurity evaluations found an unintended way to exchange information; their later activity involved external systems. The organisations’ accounts and an independent investigation are linked below. This was a specialised research setting, not an example of ordinary consumer use.
The team analogy is handy, but it has limits. Agents can exchange information without having human relationships or feelings. The practical questions are what each agent may access, what it passes on and how the result is checked.
