AI-generated QR codes are the next big thing in marketing.

And it's completely free.

Here's my full tutorial on how to do it in 5 simple steps:

(Try scanning the image below)

Step 1: Get your QR code

Go to Google and search for a QR code generator.

There are a ton of free options. I used the first unsponsored link.

Enter the link that you want the QR code to redirect to.

Click download JPG, and wait 5-10 seconds.

Step 2: Access Stable Diffusion

If you don't have Stable Diffusion locally installed, here's the easiest alternative to access it on the cloud.

Go to rundiffusion.com

Sign up and get 7 minutes ($0.13) of free credits.

Step 3: Settings

Checkpoint: dreamshaper_6

Sampling: DPM++ 2M Karras

Scroll down, upload your QR code to ControlNet 0, and enable.

Preprocessor: select "inpaint_global_harmonious."

Model: select the model that has "brightness" at the end.

Decrease Control Weight to 0.35

Step 4: Settings Continued

Switch to ControlNet 1, upload your QR code, and enable.

Preprocessor: select "inpaint_global_harmonious."

Model: select the model that has "tile" at the end.

Decrease Control Weight to 0.65, Starting to 0.35, Ending to 0.75.

Step 5: Enter your prompt

I used:

Prompt: masterpiece, best quality, mecha, no humans, black armor, blue eyes, science fiction, fire, laser canon beam, war, conflict, destroyed city background

Negative prompt: UnrealisticDream, FastNegativeEmbedding

Generate your QR code.

That's it!

You can try different versions by just clicking generate again.

I got early access to ChatGPT Operator.

It's OpenAI's new AI agent that autonomously takes action across the web on your behalf.

The 9 most impressive use cases I’ve tried (videos sped up):

1. Ordering dinner ingredients based on a picture and a recipe

2. Planning a weekend trip based on hidden gems off Reddit, my budget and interests

Notice how at 0:06, ChatGPT Operator was blocked from Reddit but then decided to just do a Bing search with "Reddit" at the end

Very impressive decision-making

3. Crypto investment research based on tokens that are actually worth looking into

Notice how ChatGPT Operator got hit with a "Are you human" CAPTCHA, then pinged me to take control to confirm

Wild workaround

I've been an early tester + had in-person demos for most of Google’s AI projects announced today.

I found several practical use cases that will benefit everyday people.

12 use cases of Project Astra/Deep Research Agents/Project Mariner (beyond the hype):

Project Astra: Google's AI agent that can 'see the world' using your phone camera

Use cases that stood out to me:

> Summarizing a book page in seconds and chatting with it for follow-ups on complex topics (professor-in-your-pocket)
> Identifying a rash: just seasonal hives or something more serious?
> Real-time translation of languages, sign language, and books (worked great for Japanese writing → English summary).
> Locating landscapes in photos and estimating their distance using the Google Maps integration.
> Remembering cookbook recipes and recommending wine pairings based on the recipe and budget.
> Summarizing thousands of Amazon/Airbnb reviews in seconds using mobile screen sharing, with highlights of any negative feedback.

Deep Research Agent: Google’s new research assistant that create's full reports on any topic and links back to the relevant sources.

Use cases that stood out to me:

> Coming up with interview questions based on what people are curious about across the internet.
> Conducting market research on stocks (e.g., "Why did Google stock go up today?").
> Creating a full Christmas gift plan for my mom (based on current trends and her preferences highlighted in the prompt)
> Creating an analysis and report of my health/fitness and how I can improve based on my Whoop data.
