Hi Reader ,

I want to share something with you.

Claude released Fable 5.2. I got super excited. I decided to make the best CFO dashboard ever.

21% of my weekly usage. Gone.

But at least you can watch the result here:

What came back from a single prompt:

→ P&L, balance sheet and cash flow that reconcile every month

→ A live "Integrity" badge that proves it

→ Profit bridge from budget to actual EBITDA

→ 13-week cash forecast with a minimum-cash line

→ Scenario sliders that recalculate the whole model in real time

→ 1,000 Monte Carlo simulations of cash

→ A CFO briefing that rewrites itself when the numbers change

It can create AMAZING dashboards.

But here is the part nobody tells you: Opus 5.5 can as well.

So when should you use which?

My opinion after this test:

Opus 5.5 is your daily driver.

Variance commentary, KPI dashboards, budget templates, quick scenarios. Fast, good, and easy on your limit.

Fable 5.2 is for when being wrong is expensive.

Three statements that must tie out. Ten moving parts in one build. Work you want checked before you see it.

The real difference was not the design. Fable checked its own work, found numbers that were typed in instead of calculated, and fixed them before handing it over.

That is what the 21% bought me.

See it move here (the sliders are the best part):

​Here is the full prompt.

Also, I released a full guide on this model here.

Thanks and hope this helps!
