Get Claude Opus 4.7 for Free, $100 Credit, Limited Time

I’m Yang Qing, an architect with 10 years of big tech experience turned solopreneur. I deconstruct business from a technical perspective to help you avoid common pitfalls.
The content I share covers: boosting efficiency with AI tools, taking independent products global, and solopreneurship methodologies.

A few days ago, I told some friends who do AI coding about a site where you could grab GPT-5.5 for free.

Today that site just dropped something new.

This time it’s Claude Opus 4.7, with $100 in free credit.

To be honest, I’m a heavy Claude Code user myself. I burn through several hundred bucks a month just on API fees.

What is Opus 4.7? It’s the strongest model Anthropic has right now. Writing code, designing architecture, debugging — it’s ceiling-level across the board.

What does $100 mean? Enough to finish a mid-size project on Opus, or run a few hundred complex agent tasks.

Honestly, this is one of the highest-value freebies a normal person can grab right now.

Enough talk. Let’s get to the tutorial.

Step 1: Sign Up and Get Your API Key#

Sign up here (you need my invite code to get the $100 credit):

👉 https://freemodel.dev/invite/FRE-16824e34

After you’re in, create an API Key and copy it somewhere safe.

Step 2: Install Claude Code#

First, make sure you have Node installed:

1
node --version

If not, grab the LTS version from nodejs.org.

Then one line to install Claude Code:

1
npm install -g @anthropic-ai/claude-code

---

Step 3: Configure settings.json#

This step is the key one. You’re telling Claude Code to route its requests through freemodel’s proxy.

Config file location:

• Mac/Linux: ~/.claude/settings.json
• Windows: C:\Users\<your_username>\.claude\settings.json

If the .claude folder doesn’t exist, run claude once in the terminal and it’ll create itself.

Then paste this into settings.json:

1
{
2
    "env": {
3
        "ANTHROPIC_API_KEY": "YOUR_API_KEY",
4
        "ANTHROPIC_BASE_URL": "https://cc.freemodel.dev",
5
        "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1"
6
    },
7
    "permissions": {
8
        "allow": [],
9
        "deny": []
10
    },
11
    "apiKeyHelper": "echo 'YOUR_API_KEY'"
12
}

Replace both YOUR_API_KEY placeholders with the key you got in Step 1.

---

Step 4: Switch to Opus 4.7#

Open Claude Code, and type in the prompt:

1
/model

Then pick Claude Opus 4.7.

Done. Every prompt you write now runs on Opus 4.7, completely free, until the $100 runs out.

Wrapping Up#

These free credit windows tend to close fast. First come, first served. Once it’s gone, it’s gone.

Here’s the link one more time, I’d suggest signing up right now:

👉 https://freemodel.dev/invite/FRE-16824e34

If you’ve never used Claude Code before, seriously, spend 10 minutes trying it out.

As someone who’s been writing code for 10 years, I’ll say this with confidence: Opus 4.7 writes code better than 80% of junior and mid-level engineers.

This $100 might be the moment you really see what “AI coding” can do.
