Cline CLI 2.0: Free team of AI agents for coding right in the terminal

Hey, coders! If you don’t want to pay $200 a month for GPT Pro or other premium tools, I have good news for you. Now you can run a whole team of AI agents to help with coding absolutely free of charge and all this in your terminal.

The open source version of Cline CLI 2.0 was released. Let's figure out what it is, why it's cool and how to use it.

## What is Cline CLI and why is 2.0 a breakthrough?

Cline CLI is a tool that turns your terminal into a powerful hub for working with AI. Imagine: you write code, and AI helps fix bugs, refactor, write tests, or even build entire features. And all this is not in some cloud, but locally on Windows, macOS or Linux.

Version 2.0 added a bunch of chips, but the main thing is the parallel work of AI agents**. This means that several assistants can work at the same time. One agent fixes bugs, another improves code, a third generates tests - and they don't interfere with each other. The result? You save time and nerves, and the project moves faster.

Another plus: support for any AI models, providers and editors**. Do you want Claude, GPT or something? Easy to connect. Works with VS Code, JetBrains, Zed, Neovim, Emacs – choose which is more convenient.

And now the cherry: free models from opensource kings**. Minimax M2.5 and Kimi K2.5 are available without API keys for a limited time. That means you can test the power of AI without a penny. Of course, you will need a key from Anthropic or another provider to work permanently, but the start is free!

Install simple: download from the official website cline.bot/cli. It's full documentation.

## Claude Opus 4.6 – Deep Thinker at Cline

If you’re looking for top AI for complex tasks, Anthropic has released Claude Opus 4.6. Everyone calls him "Deep Thinker" and for good reason. This model thinks deeply, understands you in half a word, and delivers clean code without undue oversight. It is already integrated into Cline, both in editorial extensions and in CLI.

### What's new in Opus 4.6?

This is an upgrade from Opus 4.5, which was already one of the best for coding. Key improvements:

• Best reasoning: The model analyzes complex problems before action. The Benchmarks show a jump in ARC-AGI-2, which means it's smarter.
• Long context: A 1 million token window holds your entire codebase in mind. Perfect for big projects.
• Agent tasks Works independently without your constant supervision.

The price remained the same: $5 for a million input tokens, $25 for the weekend. Available with your Anthropic API key.

### How does that feel in practice?

I tested the Opus 4.6 in Cline and noticed this:

** Sees what you mean** Even if your prompt is curved or vague, the model guesses the intent. You can chat with your voice (via voice-to-text), explain the idea and it will ask clarifying questions, rather than messing up. It feels like talking to a colleague, not a robot.

• Pure communication. The answers are brief, without too much text. There are no walls of explanation, only what is needed. It saves time: less scrolling, more code.

Refactoring and long projects. For big changes, great. The model remembers everything, makes coherent edits on several files. If you’ve been putting off the refactor for fear that AI will get entangled, then try Opus 4.6.

Best design. When generating UI, the code is modern and consistent. The elements are not just piled up, but thought out. For the frontend - a noticeable upgrade.

### Opus 4.6 in Cline CLI: Where it really shines

In the terminal, this model is fully disclosed. CLI lets you run Opus offline – and here its “deep thinking” works wonders.

Autonomous execution. Give a goal - the model will break down into tasks, go to files, run commands and do the job. With the auto-approve function, you can move away and return to the finished result. Less supervision means more productivity.

**Less words, more deeds. Short instructions are enough. No need to describe each step – the model will plan.

Adaptive thinking. The model decides how much to think: fast for the simple, deep for the complex.

### Cons and when to choose Opus vs Sonnet

Opus 4.6 thinks longer on complex tasks – pause before answering. It's not a bug, it's a feature: deep analysis. If you need it instantly, use Sonnet for simple iterations.

Choose Opus for:

• Complex refactors, multifile changes.
• Debugging, cause analysis.
• Autonomous work in CLI.
• A frontline with good design.

Sonnet for speed: quick cycles, simple tasks.

## How do I start?

In Cline, select claude-opus-4.6 in the model selection. Works with your Anthropic API key.

• Extensions: VS Code, JetBrains, etc.
• In CLI: Install/update Cline, select the model. Try auto-approve for a refactor or a new feature.
