Hey everyone, this is 程序员晚枫 (Programmer Wanfeng).

Today I'm bringing you a special tutorial for Kimi Coding Plan, focusing on how to use its 128K ultra-long context to process large code projects — Kimi's unique secret weapon.

1. Kimi's Killer Feature: 128K Context

What Is 128K Context?

Simply put, it's how much content AI can "remember" at once. Regular AI might only handle a few K tokens — Kimi handles 128K tokens.

128K tokens is roughly equal to:

100,000 Chinese/English characters mixed
Hundreds of source code files
All the code in a small-to-medium project

Why Does This Matter?

Before, when using AI to analyze code, you needed to:

Split the code into small chunks
Feed chunks to AI one by one
AI might "forget" previous content

Now with Kimi, you can:

Feed the entire project's code in at once
AI understands everything at once
Get much more accurate analysis

2. Practice: Analyze a Large Project with Kimi

Scenario: Analyze a Python Project

Say you have a Python project containing:

main.py
utils.py
models.py
config.py
20 other files

Step 1: Prepare the Code

Organize the files you want AI to analyze (you can zip them into one folder).

Step 2: Describe Your Need

Give Kimi a clear task:

Help me analyze this Python project:
1. What is the project structure?
2. Where is the core business logic?
3. What are the potential bugs or optimization points?

Step 3: Get Analysis Results

Kimi will provide analysis based on complete context — much more accurate than feeding code in chunks.

3. Other Kimi Use Cases

1. Code Review

Help me review the entire project's code and find:
- Potential bugs
- Security risks
- Code style issues

2. Large Refactoring

1 2	I want to refactor this project from MVC to Clean Architecture. Help me analyze which areas need changes?

3. Learning a New Project

I just took over this project. Help me:
1. Understand the project architecture
2. Find the core modules
3. Explain how to get started

4. FAQs

Q1: Is 128K Enough?

For most projects, 128K is more than enough. Even large projects can be processed in batches.

Q2: How's the Response Speed?

Processing large amounts of context takes longer than short text, but usually within 10 seconds.

Q3: Is It Expensive?

Specific pricing depends on the official site, but considering the convenience of long context, the value is solid.
