Api access to open models for free with Cloudflare

What if I told you there is a way to get API access to some of the most powerful AI models completely free?

If you are constantly hitting the API endpoints for OpenAI, Anthropic, or Google, those fractional pennies per token start to add up into a massive monthly bill. It’s the biggest bottleneck for indie hackers, students, and small startups trying to build the next big thing. 💸

Here's when Cloudflare enters the chat with its Cloudflare Workers AI. 🚀

If you thought Cloudflare was just for DDoS protection and DNS, it’s time to update your playbook. Here is exactly how you can use their global network of GPUs to run premium AI models without spending a dime.

What Models Are We Talking About?

Before we dive into the setup, let's clear the air. Cloudflare is not going to magically give you a free API key for proprietary models like GPT-4o or Claude 3.5 Sonnet. Those are locked behind corporate paywalls.

However, they do give you free API access to the absolute top-tier Premium Open-Weights Models. We are talking about models that punch in the same weight class as the paid giants:

• Meta's Llama 3 (8B) - One of the fastest and smartest models available.
• Mistral & Mixtral - The European powerhouses of coding and logic.
• Qwen 1.5 - Incredible for multilingual tasks.
• Whisper (OpenAI) - Top-tier speech-to-text.
• Stable Diffusion XL - Premium image generation.

For 90% of use cases (chatbots, summarization, categorization, basic coding), these models are more than enough. And with Cloudflare, they run on serverless GPUs right at the edge, meaning the latency is mind-blowing. 🤯

The Free Tier: Is it actually free?

Yes! Cloudflare’s free tier for Workers AI is incredibly generous for developers.

They use a metric called "Neurons" to measure compute. On the free tier, you get 10,000 Neurons per day. To put that in perspective, that is roughly equivalent to generating thousands of responses or classifying thousands of texts every single day.

If you are just prototyping, building a personal tool, or running a low-traffic app, you will likely never hit this limit.

Step-by-Step: How to Get Your Free API Access

Get ready to swap out those expensive API keys? Here is how to set it up in under 5 minutes.

Step 1: Create a Cloudflare Account

If you don't have one, head over to Cloudflare.com and sign up.

The good thing about this platform is that you don't even need to add a credit card to use the free AI services.

Step 2: Find Your Account ID

Log in to your dashboard. Look at the URL in your browser—the long string of letters and numbers right after dash.cloudflare.com/ is your Account ID. Save this, you'll need it.

Step 3: Generate an API Token

1. Click on "My Profile" (top right icon) -> "API Tokens".
2. Click "Create Token".
3. Scroll down to "Custom Token" and click "Get started".
4. Name it something like "Workers AI Access".
5. Under Permissions, select: Account | Workers AI | Read.
6. Click "Continue to summary" and then "Create Token".
7. Copy this token immediately! It will only be shown once.

Step 4: Make Your First API Call! 💻

You now have everything you need.

You don't even need to write a Cloudflare Worker to use this; you can hit the REST API directly from your local terminal, your Python backend, or your Next.js app.

Here is how you test it using a simple cURL command in your terminal (just replace the bracketed info with your actual IDs):

Bash

curl -X POST \
"https://api.cloudflare.com/client/v4/accounts/{YOUR_ACCOUNT_ID}/ai/run/@cf/meta/llama-3-8b-instruct" \
-H "Authorization: Bearer {YOUR_API_TOKEN}" \
-H "Content-Type: application/json" \
-d '{
  "messages": [
    {"role": "system", "content": "You are a helpful, sarcastic AI assistant."},
    {"role": "user", "content": "Explain quantum computing in one sentence."}
  ]
}'

Hit enter, and within milliseconds, Llama 3 or your choice of model will stream a response back to you, powered by a serverless GPU that you didn't have to pay for. 🥳

If you are building an enterprise app that absolutely requires the deep reasoning of GPT-4, you still have to pay the toll.

But for side projects, hackathons, MVPs, and daily automation scripts? Paying for API credits is becoming optional.

Cloudflare Workers AI has essentially democratized access to premium-grade open models.

It’s fast, it’s secure, and best of all—it keeps your wallet happy. 🚀
