Three Ways to Try MiMo V2.5 Pro
1. Xiaomi MiMo Studio
The easiest way to test MiMo V2.5 Pro is through Xiaomi MiMo Studio in the browser, where you can try the model directly before setting up an API or coding environment. You can use it to generate a high-quality portfolio website in a single HTML file, including animations, interactive sections, and polished visuals. It is a good starting point if you want to quickly test the model design, coding, and instruction-following abilities without any setup.
2. Xiaomi MiMo API Open Platform
You can also test the model through the Xiaomi MiMo API Open Platform. When you create an account, you receive around $0.72 in free credit, but it may be used up after only a few prompts. This pushes you to look into the Token Plan, which offers discounted API access with monthly token usage.
3. MiMo Token Plan for Coding
For coding tasks, the Token Plan looked much cheaper than adding standard API credit directly. Due to promotions, you can get the Lite Token Plan for around $4.62, which makes it roughly 10x cheaper than using normal pay-as-you-go API credit. The coding Token Plan supports several popular coding and agent tools including OpenCode, Claude Code, OpenClaw, Hermes Agent, Cherry Studio, Qwen Code, CodeBuddy, and Cline.
Monitor Token Usage Carefully
Coding agents can consume tokens quickly because they repeatedly read files, call tools, and send long context back to the model. Monitor your token usage carefully to avoid running through your monthly quota too fast.
Step by Step Guide to Install OpenCode and Set Up MCP
Before setting up Olostep MCP, you first need to install OpenCode. We will use Olostep because it gives our coding agent access to web search, web scraping, and documentation-to-code tools. This is useful when testing MiMo V2.5 Pro, because the model can quickly check the latest framework documentation instead of relying only on its training data. This helps reduce mistakes, outdated code, and incorrect API usage.
Install OpenCode CLI
The easiest way to install OpenCode is through the official install script. In your terminal, run: curl -fsSL https://opencode.ai/install | bash. This installs the OpenCode CLI on your machine. After installation, verify with opencode --version and start with opencode.
Create Your Olostep API Key
Create a free Olostep account, then go to the Olostep dashboard and create or copy your API key. Olostep requires an API key before you can use either the hosted MCP server or the local npx server. Keep the API key somewhere safe, as you will need it when updating the OpenCode config file.
Add the Olostep MCP Server
In your terminal, run opencode mcp add. OpenCode will start the MCP setup flow. Use these values: MCP server name: Olostep, MCP server type: Remote, MCP server URL: https://mcp.olostep.com/mcp, OAuth authentication: No.
Update the OpenCode Config File
After OpenCode adds the MCP server, it will show you the location of your config file. Open this file and update the Olostep MCP configuration so it includes your authorization header with the Bearer token format.
{
"$schema": "https://opencode.ai/config.json",
"mcp": {
"Olostep": {
"type": "remote",
"url": "https://mcp.olostep.com/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
},
"enabled": true
}
}
}
Confirm the MCP Server Is Connected
Once the config file is saved, run opencode mcp list. You should see Olostep listed as one of your MCP servers. This confirms that OpenCode can now connect to Olostep through MCP.
Setting Up Xiaomi MiMo V2.5 Pro in OpenCode
Go to the Xiaomi MiMo API Open Platform dashboard, Subscription Details, and create a new Token Plan API key. This key is different from the regular API key because it is linked to your Token Plan subscription and lets you use the model through your plan allowance.
In the same section, check your Dedicated Base URL. Xiaomi shows different base URLs depending on the region or server your Token Plan is assigned to. For example, sgp refers to Singapore. Yours may show a different region, such as China or another supported server. The base URL is important because you need to select the matching Xiaomi Token Plan provider inside OpenCode.
Connect MiMo V2.5 Pro in OpenCode
Open your terminal, create a new project folder with mkdir mimo-project and cd mimo-project, then launch opencode. Inside OpenCode, run /connect. Search for Xiaomi, select the Token Plan option that matches your server region, paste your Token Plan API key when prompted.
Select Model and Test
Once the connection is complete, OpenCode will ask you to select a model. Choose MiMo-V2.5-Pro. Then set the thinking level to Medium. Send a quick test prompt. If the model responds successfully, your Xiaomi MiMo V2.5 Pro setup in OpenCode is ready.
Building a Simple Python CLI with MiMo V2.5 Pro
We will start with a simple project that is useful, easy to build, and quick to test. Ask the agent to create a Python CLI app that tracks live cryptocurrency prices. It should let users enter a coin symbol like BTC or ETH, fetch the current price from a public crypto API, display the price clearly in the terminal, and include basic error handling for invalid symbols or API issues.
Within a few seconds, MiMo V2.5 Pro started creating the Python CLI app and added the core functionality for checking live crypto prices. In less than a minute, we had a working command-line app. To test it, open another terminal window and run python crypto_tracker.py. You can also ask the agent to test the app for you.
Building a Python Web App with MiMo V2.5 Pro
Next, we moved from a simple CLI project to a complete Python web application with a frontend. To make the test more realistic, we asked MiMo V2.5 Pro to expand the previous crypto tracker into a Reflex web app. Reflex is still a relatively new Python web framework, and many models struggle to build proper apps with it. So, instead of asking the model to code immediately, we asked it to search the latest Reflex documentation first using Olostep.
Build a beginner-friendly Python crypto price tracker using Reflex.
Search the latest Reflex docs before coding, keep everything in Python,
include live prices, useful charts/graphs, clean UI, error handling,
and simple setup/run instructions while deciding the best
implementation details yourself.
As soon as the prompt was entered, MiMo V2.5 Pro created a to-do list and started searching the latest Reflex documentation through Olostep. It scraped the important documentation pages, gathered enough context, and then began building the Reflex app from scratch. Once the app was complete, the agent provided a summary of what it built, the files it created, and the steps required to run the project.
After confirming the app was working, test it by running cd crypto_tracker then reflex run. The app starts locally at http://localhost:3000.
Improving the UI
The first version may have UI issues such as numbers overflowing outside cards, input text being too dark and partially clipped, and stats not clearly visible. Ask MiMo V2.5 Pro to improve the UI by fixing the search input so the placeholder is fully visible, formatting prices and stats with currency symbols and commas, replacing zero values with real API data, improving chart spacing and tooltip, and connecting a Watch button to a simple watchlist.
Within a few minutes, it fixed the main UI issues and made the app feel much more polished. The final web app was interactive, fast, and modern. You can type a crypto symbol manually or click one of the popular token tags. The app displays live price data, market cap, 24-hour volume, 24-hour high, and 24-hour low. It also includes charts for different time ranges such as 1 day, 7 days, 30 days, and 90 days. On top of that, you can add coins to a simple watchlist.
| Feature | Description | Implementation |
|---|---|---|
| Live Price Data | Fetches real-time crypto prices from public API | Coin symbol input or tag click |
| Market Statistics | Displays market cap, 24h volume, high, and low | Formatted with currency symbols |
| Price Charts | Interactive charts for multiple time ranges | 1 day, 7 days, 30 days, 90 days |
| Watchlist | Save favorite coins for quick access | Watch button connects to list |
| Dark Theme | Modern dark UI with proper contrast | Reflex Python components |
Final Thoughts on MiMo V2.5 Pro for Vibe Coding
After using MiMo V2.5 Pro for almost a full day, the model is fast, responsive, and much better at building projects from scratch than expected. Compared with other models, it feels more direct. It starts building quickly, tests things fast, and does not spend forever thinking before doing the work.
The main concern is the Token Plan. Even though it is subsidized, you may reach almost 50 percent of your Lite plan quota in around three hours, which feels like a lot for one coding session. Since the quota resets monthly, heavy agentic coding can burn through it quickly.
One issue to note is tool compatibility. MiMo worked well with OpenCode, but there were problems using it with tools like TRAE, Cursor, Roo Code, Codex, GitHub Copilot CLI, and Pi Code. It seems related to how some agent frameworks handle reasoning_content in multi-turn conversations.
Tool Compatibility Note
MiMo V2.5 Pro works well with OpenCode, but may fail with tools like Cursor or Codex due to how they handle reasoning_content in multi-turn tool call conversations. OpenCode handles this correctly, which is why it is the recommended tool.
Key Insight:
Overall, MiMo V2.5 Pro is fast, capable, and surprisingly good for real coding projects. For regular agentic coding, compare it with options like Moonshot or Z.ai, especially if you want more predictable usage. But the model itself is genuinely impressive and worth testing.
