How are AI agents different from chatbots?

Question

Accepted Answer

AI agents and chatbots both use language models, but they're built for different jobs.

Chatbots are conversation-focused. They take your input, generate a reply, and that's the loop. The "action" happens almost entirely inside the text — they inform, explain, or assist, but they don't go out and do things in the world on your behalf. The model of responsibility is basically: you talk, it talks back.

Agents are action-focused. An agent is designed to take a goal, break it into steps, and execute those steps using tools — making API calls, moving funds, querying databases, reading a smart contract, executing a trade, retrying on failure, and chaining multiple operations until the objective is done. It's not a one-shot reply; it's a loop of plan → act → observe result → adjust → act again.

Concrete differences:

	Chatbot	Agent
Core loop	Input → reply	Input → plan → act → observe → adjust
Tools	None (or minimal)	Can call APIs, contracts, browsers, wallets
Persistence	Stateless conversation	Holds state across steps and can verify outcomes
Autonomy	Stops after each reply	Can run multi-step toward a goal without prompting each time
Failure handling	Just re-answers	Retries, picks a different path

In crypto specifically, the difference gets very real: a chatbot can explain a swap, but an agent can execute it — check token prices across DEXs, route through the best liquidity pool, approve the contract, submit the transaction, and verify the swap landed. That's also exactly why agents carry more risk: more autonomy means more surface area for bad instructions, compromised tool permissions, or an agent that keeps going down a path you didn't intend.
