Kimi K3

Open frontier model for coding and knowledge work

Kimi K3 is Moonshot AI’s frontier model launched through Kimi’s product suite. The launch post describes it as a 2.8T-parameter model with native vision capabilities and a 1-million-token context window, and says it is the first open 3T-class model.

The model is available across Kimi.com, Kimi Work, Kimi Code, and the Kimi API. Across the source pages, Kimi K3 is positioned for long-horizon coding, knowledge work, and reasoning rather than as a single-purpose chat model. Kimi Work uses it for desktop automation and agent workflows, while Kimi Code presents it as a code agent for developer tasks.

Core capabilities

Large-context multimodal model

The page describes Kimi K3 as a 2.8T-parameter model with native vision and a 1-million-token context window, built for long-horizon coding, knowledge work, and reasoning.

Developer-oriented code agent

Kimi K3 is presented as the model behind Kimi Code, where it is positioned for coding tasks, terminal tool use, and work across large repositories.

Local desktop workflow automation

Kimi Work is described as a desktop local agent that mounts local folders, runs Python in the background, and works continuously on the desktop.

Browser automation with WebBridge

WebBridge lets Kimi Work browse like a human, move across tabs, and extract information from websites for multi-step web tasks.

Scheduled automation

The product page says Kimi Work includes a Cron engine for LLM agent calls, Python/Shell execution, and recurring tasks that can run on a schedule.

Multi-agent research and office output

Kimi Work includes Swarm-based coordination of multiple specialized agents, then turns completed research into PowerPoint decks or Excel sheets.

Practical use cases

  • Developer coding workflows

    Use Kimi Code when you need an AI coding assistant that can work inside terminal and IDE-oriented workflows, help with large repositories, and support programming tasks with a long context window.

  • Desktop knowledge work

    Use Kimi Work for desktop tasks that combine local files, browser actions, and background scripts, such as finding documents, summarizing them, or running repeated office automation.

  • Automated web research

    Use the browser automation layer when a task requires web research, tab navigation, data extraction, or copy-to-Excel style workflows without manual clicking.

  • Recurring automation

    Use Kimi Work’s scheduled tasks when you need recurring LLM calls or Python/Shell jobs to run on a daily, hourly, or conditional basis.

  • Long-form research and analysis

    Use Kimi K3 for long-horizon reasoning tasks that mix code, visuals, and research, such as scientific workflows or interactive reports.

Pros and Cons

Pros

  • 1M-token context supports long documents, large codebases, and extended workflows.
  • Native vision capabilities let the model work with screenshots and other visual inputs.
  • Kimi Work combines local files, browser automation, background execution, and scheduled tasks in one desktop agent.
  • Kimi Code is presented as a developer workflow tool with CLI support and a one-subscription model.
  • The product suite spans web, desktop, coding, and API access.

Cons

  • The launch post says Kimi K3 still trails the most powerful proprietary models overall, even though it performs at a frontier level in the reported evaluations.
  • Pricing, plan structure, and enterprise terms are not detailed in the provided pages.
  • The coverage provided here is stronger on product positioning than on complete integration and setup documentation.

FAQ

What is the difference between Kimi Work and the web version?

Kimi Work is the desktop agent for deeper workflows: it mounts local folders, can navigate the web through WebBridge, runs Python code in the background, and supports scheduled tasks. The web app is described as better for quick chat and queries.

How does Kimi Work handle local-file privacy and permission?

The page says Kimi Work gives you control over your files and uses an “Ask before acting” safeguard. It prompts for explicit authorization before modifying, overwriting, or running code in local directories.

What can WebBridge do?

WebBridge is Kimi Work’s browser-automation layer. It can browse across tabs, click, scroll, extract data, and complete multi-step web tasks such as checking news, summarizing pages, or scraping stock data into Excel.

What kinds of scheduled tasks does Kimi Work support?

Kimi Work’s Cron scheduler supports LLM agent calls, Python/Shell executions, and other scheduled automation. The page says tasks can run daily, hourly, or conditionally, and that you can use the Keep Computer Awake option if you want overnight execution.

Where is Kimi K3 available?

Kimi K3 is available on Kimi.com, Kimi Work, Kimi Code, and the Kimi API. The launch post says full model weights will be released by July 27, 2026, but it does not describe separate model plans or pricing on the source pages provided.
