By day, I’m a professional housepainter.

In May 2025, I started vibe-coding with AI — driven by curiosity.

Since then I’ve built websites and shipped an Android app.

Learning in public and exploring what’s possible with AI.

If you use the OpenAI API or Codex, go check Settings > Billing > History right now. Auto-recharge fires silently, no warning before or after.

There's even an open GitHub issue about the toggle re-enabling itself. Set a low threshold + hard monthly cap, or you'll find out the hard way.

Starting to get why people joke about "Scam Altman."

Yesterday I had 4, today 3. Guess it expired. Today, after some coding, I used a reset and saw the meter fill up. Try to code again, and it didn't actually reset.

Used another one and that one worked, but not getting much usage anymore like before.

Contacted support but they don't give resets back, they recommend buying credits. 😒

Here’s the prompt I used:

Create a premium 16:9 e-commerce hero banner for a fictional pet supplement brand called “LumaPaws”.

Scene:
A realistic golden retriever sits in a warm modern Scandinavian kitchen during golden-hour sunlight. On the left side is clean website hero copy and product information. On the right side is the dog and the product bottle. The dog’s front paw should break slightly out of the image frame and rest naturally on the CTA button, creating a layered 3D website effect.

Product:
A small amber glass pump bottle labeled “LumaPaws Omega Oil”. The bottle contains salmon oil for dogs. The label must be sharp, readable, and professionally designed. Include a small salmon icon, subtle omega-3 droplet icon, and the text:
“LumaPaws”
“Omega Oil”
“Salmon Oil + Omega Fatty Acids”
“For Healthy Coat & Skin”
“250 ml”

Website layout:
Top navigation bar with the links:
“Shop”
“Benefits”
“Reviews”
“FAQ”

Main headline:
“Shinier Coat. Happier Dog.”

Subheadline:
“Daily omega support made simple. Just add a few pumps to their food.”

CTA button text:
“Shop Omega Oil”

Add three small benefit cards below the headline:
“Coat Support”
“Skin Comfort”
“Easy Daily Pump”

Visual style:
Premium pet brand, warm beige and soft sage color palette, clean white space, polished Shopify-style design, realistic materials, soft shadows, shallow depth of field, natural dog fur texture, accurate reflections on the glass bottle, realistic kitchen lighting, cinematic but believable.

Important constraints:
All text must be spelled exactly as written.
No fake extra words.
No distorted letters.
No real brand logos.
Do not make it look like a generic AI poster.
Make it look like a finished homepage hero section a real pet brand could use.

Just tested Seedream 5.0 Pro.

I gave it a full e-commerce hero banner prompt for a fictional pet supplement brand. layout, product label, CTA, benefit cards, dog pose, lighting, everything.

It pretty much nailed it.

GPT Image 2 finally has a serious contender. 🤯

This old Swedish commercial always make me smile 😂

[Jan Walter @JanwalterAI]

Finished my latest AI spec ad: L’INSTINCT.

A cinematic perfume film about scent, instinct, and the search for the perfect gift.

Built with my storyboard tool, GPT Image 2, Seedance 2.0, Suno, and DaVinci Resolve.

When I asked Fable 5 to check my site for why it's no longer ranking on Google. 😬

Time to get to work.

Paris, this afternoon.

100% AI-generated, zero permits, zero crane. Nano Banana + Seedance 2.0. (Seedance didn't add a driver, but that was easily fixed with Omni Flash).

Been heads-down since my last post: learning DaVinci Resolve, building AI spec ads, and just generally drinking from the AI firehose.

Side effect: hundreds of browser bookmarks in total chaos.

Tried Anthropic's Cowork for the first time today. It read all 860 of them, reorganized everything into logical folders right in my browser, and even built me a DaVinci Resolve learning library.

Wild stuff.

@petergyang You could also animate it with the Animomo app.

@robinebers This is wild! Too afraid to even try it. 😂

[Jan Walter @JanwalterAI]

Built a repeatable Instagram Reel workflow for Animomo today in Codex. It's time to promote the app, and maybe I will make more than 10 USD MRR 😂

Tools used:

GPT Image 2 / Seedance for the coloring page + realistic coloring/photo scenes

Google Flow, Flash model, for the final animation scene

FFmpeg for local reel assembly

CapCut for final editing and Suno for background music
