Every hidden instruction exposed.

The same repo that previously leaked ChatGPT, Gemini, Grok, Cursor, Lovable, Replit, and Perplexity.
Here is what it actually reveals:
Fable 5 and Mythos 5 share the same underlying model. Fable gets extra safety layers. Mythos doesn't, but is restricted to approved organizations only.

BEFORE YOU BUILD WITH AI, UNDERSTAND HOW IT WAS BUILT.
The 5-stage pipeline behind GPT and Claude in one infographic:
- Data quality over quantity.
- Tokens are pieces of words, not ideas.
- Training is mostly next-token prediction.
- Alignment turns intelligence into usefulness.
- Inference is where prompts become answers.
The builders who understand this build better than the ones who don't.
Save this.

what did you build while we had fable 5?

Most people using Claude Code are accidentally burning money every day on tools that should have been free after the first session.
A senior engineer with 10 years of experience explained why in one Reddit post:
They’re calling the AI every time the tool runs. That’s the expensive way. Every execution burns tokens. The cost compounds daily, forever.
The free way: use Claude Code to write the tool once.
A scraper. A monitor. A neural network. Anything that runs on compute without touching the API again after it’s built.

Give me ninety seconds instead and I'll show you how to use AI to save money.
Shaders by Moda is out now. Type one sentence and you basically get the liquid glass effect that a $40k per video motion designer could exclusively do.
Fully editable, animated graphics for slides, ads, posts in ANY size
You can spend some time messing around with this and upgrade your setup or spend that $40k over and over again.
For your own good - actually try it, don’t just save this and forget it exists.

+1 🎈🎂
Birthday today. Reflecting on how far this has come.
A year ago I wasn’t sure anyone cared about what I was building.
Now I wake up every day with a community of people who are genuinely trying to build something better with AI.
That’s rare. And I don’t take it for granted for a single day.
If you’re early in your journey right now stay. The compounding is real. The people who show up consistently always win.
Thank you for being part of this. The best is still ahead.

THE TOP 5 MOST USED AI MODELS RIGHT NOW AND THE RANKING WILL SURPRISE YOU.
ChatGPT — still the most recognized name in AI
Gemini — Google's distribution advantage is real
Claude — the model serious builders actually reach for
Microsoft Copilot — 1.2 billion Microsoft users is not a small moat
Perplexity — the search replacement nobody saw coming
The gap between what most people use and what the best builders use tells you everything about where the real leverage is.
Which one is in your daily stack?
