BlueRun Ventures' early-stage project Moonshot AI has released and open-sourced its K2.5 model, bringing new capabilities in visual understanding, coding, and agent swarms.

Today, Moonshot AI released and open-sourced the Kimi K2.5 model:

• It is Kimi's most intelligent model to date, achieving open-source state-of-the-art performance on agent, coding, image, video, and a range of general intelligence tasks.
• It is also Kimi's most capable model, built on a native multimodal architecture that simultaneously supports visual and text inputs, thinking and non-thinking modes, and both conversational and agent tasks.

As Aristotle said: "The soul never thinks without an image." Moonshot AI's newly released and open-sourced K2.5 model gives AI more complete "eyes" and "hands" through deep integration of visual and coding capabilities and frontier exploration of agent clusters, moving intelligence from understanding to creation.

BlueRun Ventures was an early investor in Moonshot AI and has continued to double down in subsequent rounds. As a partner that has witnessed its growth every step of the way, we sincerely congratulate Kimi on reaching this new milestone. We look forward to Kimi K2.5 becoming an accessible "superpower" assistant for everyone, continuing to advance the reinvention of productivity.

Kimi believes that more intelligent, more capable models with stronger coding abilities will help democratize technology and benefit more people:

• Kimi K2.5 makes intelligence more accessible. By combining visual understanding with reasoning, coding, and agent capabilities, K2.5 lowers the barrier for users to interact with AI: when words fall short, you can simply take a photo, screenshot, or screen recording and send it to Kimi, breaking through the limits of text-based expression.
• Kimi K2.5 makes everyone proficient in Office. The K2.5 model extends Kimi's agent capabilities into daily office work, beginning to master intermediate and advanced skills in Word, Excel, PowerPoint, PDF, and other common software, helping users directly deliver near-professional-quality documents.

Kimi believes AI agents will give everyone "superpowers." Just as human society requires collaboration to handle truly complex work, K2.5 introduces "agent clusters" for the first time, allowing K2.5 to autonomously create its own "clones," assembling teams of different roles on demand to work in parallel as a squad, achieving 10x or even 100x efficiency gains.

Kimi K2.5 is now available on kimi.com, the latest Kimi app, the Kimi API platform, and our programming assistant product Kimi Code. Welcome to try it out.

For more technical details and benchmark results on the Kimi K2.5 model, please follow our technical blog and the upcoming technical report.

Code × Vision: Making Intelligence Accessible

Kimi K2.5 further elevates the coding capabilities of open-source models, especially in frontend development. The K2.5 model supports generating complete frontend interfaces from simple natural language conversations, and can effectively handle interactive layouts, scroll-triggered animations, and other dynamic effects. Below is an example of K2.5 building a website from a single prompt, with the assistance of an image generation tool:

By integrating visual capabilities, K2.5 truly lowers the barrier to programming: you can simply upload a screen recording. Kimi K2.5 automatically deconstructs the underlying interaction logic and reproduces it from start to finish with clean, professional code.

The advanced visual understanding and programming capabilities of the Kimi K2.5 model have also been validated by feedback from early API beta testers:

Among them, Keep AI Coach Kaka, built on Kimi K2.5's video action recognition and assessment capabilities, will be launching soon — stay tuned.

Agent Clusters: Giving You "Superpowers"

Six months ago, Kimi released its first trillion-parameter open-source agent model, Kimi K2. The subsequent Kimi K2 Thinking added thinking time, enabling it to independently complete long-horizon tasks of up to 300 steps. But that wasn't enough. Solving real-world complex problems can't rely on solo effort alone — it requires teamwork.

Today, we unveil Kimi K2.5's new exploration: agent clusters. This time, Kimi has evolved from a single agent to agent clusters.

When facing complex tasks, K2.5 is no longer a "jack-of-all-trades" expert that handles everything itself. Instead, it transforms into an instantly assembled "professional team." It can dispatch up to 100 clones in real time based on task requirements, processing 1,500 steps in parallel. All role assignment and task decomposition require no preset configuration — K2.5 decides everything on the fly.

Let's look at an example. Feed the Kimi agent cluster 40 papers on psychology and AI. Kimi first reads through all 40 papers sequentially through multiple tool calls, ensuring that all necessary information is fully preserved in the context. It then spawns several sub-agents — essentially Kimi "clones" — each responsible for writing different sections. Finally, the main agent oversees quality control and compiles everything into a professional PDF review dozens of pages long:

Although K2.5 has already reached advanced levels on mainstream agent benchmarks, we care more about every minute it saves users. In large-scale search scenarios, compared to single-agent execution, agent clusters reduce the minimum critical steps needed to achieve target performance by 3 to 4.5x, with savings further expanding as target requirements increase; through parallelization, wall-clock time can be shortened by up to 4.5x:

Furthermore, scaling training for agent clusters is extremely challenging. To address this, we rebuilt our reinforcement learning infrastructure and specifically optimized training algorithms to ensure peak efficiency and performance. This experimental feature is currently in beta testing and will gradually roll out in the near future. We look forward to Kimi K2.5's collaborative capabilities helping you tackle even more difficult problems.

Kimi Code Officially Launched

Since the release of the Kimi K2 series models, they have been well-received by developers at home and abroad for their outstanding performance in software engineering. Backend data from the Kimi Open Platform shows that a large number of developers are using Kimi K2 series models alongside coding agent products such as Claude Code, Cline, Roo Code, and Kilo Code. At the same time, coding agent products are increasingly demonstrating more general-purpose capabilities, with their user base expanding to non-technical professionals, pointing to enormous future potential.

Today, we officially introduce Kimi's programming tool: Kimi Code. It not only runs directly in the terminal but also integrates seamlessly into mainstream editors such as VSCode, Cursor, JetBrains, and Zed. Kimi Code fully leverages K2.5's multimodal advantages, supporting direct image and video input for programming assistance, and can automatically discover and migrate your existing skills to new workflows.

Kimi Code Bench is our internal code capability evaluation benchmark, covering various end-to-end tasks from building, debugging, refactoring, testing to scripting, supporting multiple programming languages. In our evaluation, Kimi Code powered by K2.5 showed substantial improvement compared to previous Kimi models.

We welcome you to use the Kimi K2.5 model API together with Kimi Code, or access it through Kimi's monthly membership plan at kimi.com/code.

Additionally, the Agent SDK behind Kimi Code will also be released as open source, helping everyone customize their own agent experience. We have provided more information on GitHub; details can be found at https://github.com/MoonshotAI/kimi-agent-sdk/tree/main/examples.
