What you need to know
Fable 5 is Mythos 5
with safeguards.

Claude Mythos found vulnerabilities in every major operating system and web browser in the world. It's so powerful that Anthropic refused to release it publicly. Fable 5 is the same model with safety classifiers built in — and it's now available to everyone on the Claude API, AWS, Google Cloud, and Microsoft Foundry. This is the most capable AI model ever released for public use.

The 5 Use Cases

What to do
with it today.

Fable 5's reasoning is in a different league from previous models. These are the five things worth doing with it right now.

01
Build a website
Fable 5 absolutely destroys at frontend design. Give it a brief and it builds something that would normally cost thousands from a developer. Cinematic, animated, production-ready.
→ Try this prompt
Build me a single page website for an AI receptionist business. Dark background, electric blue accents, cinematic feel. Hero section with a bold headline and book a demo CTA. Services section with 3 feature cards. Testimonials from 3 fake clients. Pricing section with 3 tiers. Animated on scroll. Premium, like a $10k agency built it. Export as a single HTML file.

02
Build an internal business tool
Instead of paying for Notion, Airtable, or a custom CRM — just describe what you need and Fable builds it. Fully functional, runs in your browser, costs nothing.
→ Try this prompt
Build me a fully working client CRM tool in one HTML file. Let me add clients with: - Name, business type, monthly payment, last contact date Show all clients in a clean dashboard. Highlight anyone I haven't contacted in 7+ days in red. Show my total monthly recurring revenue at the top. Dark theme, clean and minimal. Everything works locally in the browser — no backend needed.
Click around in the tool live on screen — add a fake client, show the revenue updating
03
Get a specific business plan built for you
Not generic advice — actually specific to your situation, your skills, your budget, your timeline. Fable's reasoning is good enough to give you a real plan that holds up.
→ Try this prompt
I am 18 years old. I have $0 to invest. I want to make $5,000/month online in the next 90 days. I have access to Claude and basic AI tools. I have about 4 hours per day to work on this. I am good at content creation and talking to people. Give me a specific 90 day business plan. Not generic advice — actual week by week actions. Tell me exactly what to do in week 1 to make my first dollar.

04
Audit your existing business
Give Fable your website, your offer, your content, and ask it to find every single thing that's costing you money or customers. Brutal, specific, actually useful.
→ Try this prompt
Act as a brutal business consultant. Audit my business and find everything that's costing me money or customers. My website: [paste your URL] My main offer: [describe what you sell] My current monthly revenue: [your number] My biggest challenge right now: [describe it] Find every gap, every missed opportunity, every red flag. Rank them by how much money I'm losing from each one. Then tell me exactly what to fix first.
Use your actual business for this — the realness is what makes it hit on camera
