Quick Answer
A Kimi agent is Kimi working on a task for you, step by step, instead of just answering one question. You give it a goal, such as research a topic and organise the findings, or work through a coding task. The agent then plans the steps, uses tools like web search or file access, checks its own results, and adjusts its plan until the task is done or it needs your help. Agent Swarm is a bigger version of the same idea, where many smaller sub agents work in parallel on different parts of a large task and then combine their results. Agents save time on long jobs, but they need clear instructions, limits, and checking, because they can also go in the wrong direction for a long time if the goal was vague.
Chat vs Agent: What Is the Difference?
Normal chat is like asking a smart friend a question. You ask, they answer, you ask a follow up. The conversation is short, and you drive every step. Agent mode is like giving that friend a project brief and letting them work on it while you do something else. You check in at the end, or at key points, rather than guiding every sentence.
How a Kimi Agent Works, Step by Step
First, you give the agent a goal in plain words. A good goal includes the outcome you want, the sources it should use, and the format you want at the end. For example: “Research the main causes of plastic waste in oceans, using recent reliable sources, and organise the findings into a clear outline with headings and a short summary under each heading.”
Second, the agent breaks the goal into smaller steps. It might search for sources, read the most relevant pages, note the main points, and check whether any important angle is missing. It does not just write the first draft it thinks of. It works through a plan, and it can revise that plan when a step fails or gives an unexpected result.
Third, the agent uses tools to gather and check information. That could mean web search, reading an uploaded file, or running code and reading the output. If a tool result shows an error, the agent can try a different approach, rather than stopping at the first failure.
Fourth, the agent produces a result you can review. That might be a document, a set of slides, a code change, or a research summary. Your job at this point is to check it. Read the result, check key facts against sources, and ask for fixes where the result does not match your goal. An agent run is not finished when the agent says it is finished. It is finished when you have checked it.
What Is Agent Swarm?
Agent Swarm is Kimi way of handling very large tasks by splitting them across many sub agents working in parallel. Instead of one agent working step by step through a huge job, many smaller agents each handle a part, and their results are combined into a final output. Think of it like a team: one person researches one angle, another researches a different angle, and a coordinator puts the pieces together.
Different Kimi versions report different swarm sizes. K2.5 was described as coordinating up to 100 sub agents. K2.6 and Kimi Work were described with up to 300 sub agents and up to 4,000 coordinated steps. Later reports about K2.6 mention up to 1,000 mini agent helpers. Those numbers depend on the product, model, and plan, so do not assume every Kimi agent run gives you the maximum swarm. The important idea is not the exact number, but the pattern: parallel work for large, divisible tasks.
Swarm work helps most when a task can be split cleanly. Researching many separate topics, checking many files, or building many similar pages are good swarm jobs. A task that needs one careful, creative decision at each step is less suited to swarm work, because splitting it can lose the thread that ties the parts together.
Kimi Work and Other Agent Products
Kimi Work is a desktop agent product from Moonshot, described as running locally on your machine with a swarm of sub agents. Reports describe four building blocks: Agent Swarm for parallel work, WebBridge, a browser extension that lets the agent use a browser like a person, a cron scheduling engine for running jobs on a schedule, and local file and code access for reading folders you mount and running code in the background.
That local desktop setup is different from web chat agent mode. Web chat agents work inside the browser and the Kimi service. Kimi Work is meant for longer, scheduled, and file heavy work on your own computer. Original files are said to stay in place unless you approve a change, which is an important safety rule for any desktop agent. Always check permissions before you let an agent access folders, browsers, or scheduled jobs.
Kimi Code is another agent product, focused on coding. It can read and edit code, run commands, and work through coding tasks in the terminal or in VS Code. We cover it in detail in our coder guide. The pattern across all these products is the same: you set the goal, the agent plans and uses tools, and you review the result.
Good Jobs for Kimi Agents
Research and organisation are strong agent jobs. Ask an agent to gather sources on a topic, summarise each one, compare viewpoints, and organise the result into a structured document. That saves you the repetitive work of opening many pages and copying notes.
Document work is another good fit. An agent can turn a long report into slides, a spreadsheet, or a structured summary, or turn rough notes into a clean draft. These jobs are valuable because they are time consuming for a human, but easy to check once the agent has finished.
Coding and data tasks also suit agents, when the task is well defined and testable. Fixing a list of small bugs, writing tests, refactoring a module, or analysing a dataset are examples where an agent can work through many steps and you can verify the result by running tests or checking the output.
Bad Jobs for Kimi Agents, and Why
Agents are a poor fit for vague goals. If you say “make something good about AI,” the agent has no way to know what good means for you, who the audience is, or what to leave out. It will produce something, but it may not be what you wanted, and you will spend more time fixing it than you saved.
Agents are also risky for sensitive or irreversible actions. Do not let an agent send emails, publish posts, change live systems, move money, or delete files without your explicit review. Those actions should always have a human checkpoint, because an agent mistake in those areas is costly and hard to undo.
Finally, agents are not a substitute for expertise on high stakes decisions. Legal, medical, financial, and safety decisions need a qualified human, even if an agent helped gather information. Use the agent to prepare and organise, and use the expert to decide.
How to Write a Good Agent Prompt
Start with the outcome, not the method. Say what you want at the end, in concrete terms. Then add constraints: which sources to use, what format to deliver, what to avoid, and how long the result should be. Then add a checkpoint: ask the agent to show its plan first, or to stop and ask you before taking an irreversible step.
An example prompt is: “Research three reliable sources on this topic. Create an outline first and show it to me before writing the full document. Do not invent statistics. If a fact is uncertain, mark it as unverified. Deliver the final result as headings with short paragraphs under each heading.” That prompt gives the agent a goal, a format, a safety rule, and a checkpoint.
After the first run, review the plan before the full result when you can. Catching a wrong plan early is far cheaper than fixing a finished document built on the wrong plan. If the plan is wrong, correct it in plain words and ask the agent to redo the plan, not just patch the final output.
What We Learned From Using Agents
We learned that agents reward clear briefs and punish vague ones. The time you spend writing a good brief is repaid in less fixing later. We also learned to start small: run an agent on a short, low risk task first, learn how it behaves, and only then trust it with larger work.
We also learned to keep a human checkpoint for every important output. An agent can work for a long time and produce a polished result that is still wrong in a subtle way. Reading the result carefully, checking sources, and testing code are not optional extras. They are the part of the workflow that makes agent work trustworthy.
Frequently Asked Questions
Is Agent mode the same as normal chat?
No. Normal chat answers one question at a time. Agent mode works through a multi step task using tools, and delivers a finished result for you to review.
What is Agent Swarm in simple words?
It is many smaller agents working in parallel on different parts of a large task, with their results combined into one final output.
Do Kimi agents cost extra?
Agent runs use more allowance than plain chat, and heavier agent features may be limited on free plans. Check your current plan before running a large agent task.
Can I leave an agent running and walk away?
For long tasks, yes, that is part of the point, but check the result before you use it, and do not leave agents running on sensitive or irreversible actions without supervision.
What is Kimi Work?
Kimi Work is Moonshot desktop agent product for longer, file heavy, and scheduled work on your own computer, with swarm, browser, scheduling, and local file features.
Final Takeaway
Kimi agents turn a chatbot into a project worker: you set a clear goal, the agent plans, uses tools, and delivers a result, and Agent Swarm splits large tasks across many sub agents working in parallel. That power is real, but it only helps when the brief is clear, the permissions are safe, and you check the final result. Start small, review the plan first, and keep a human checkpoint for anything important.
