The Mission: Weddings are expensive. The average cost is $30,000. Wedding planners cost $3,000+. I want to see if a swarm of AI agents (AutoGPT + ChatGPT) can plan a full wedding for 50 guests with a budget of exactly $5,000.

The catch: I will blindly follow their vendor recommendations (until the point of actual payment).

> AGENT SETUP

I spun up 3 instances of ChatGPT with specific personas:

  1. PlannerBot: Logistics and Budget (Persona: "Ruthless Efficiency")
  2. StyleBot: Aesthetics and Decor (Persona: "Vogue Editor")
  3. CommsBot: Writes emails to vendors (Persona: "Polite but Firm")

> DAY 1: THE VENUE HALLUCINATION

I asked PlannerBot for a venue in Austin, TX for under $1000.

PlannerBot: "I have found the perfect venue. The 'Historic Green Mansion' on 5th Street charges $500 for a Saturday event. It has a 4.8 star rating."

I Googled "Historic Green Mansion." It didn't exist.

I asked PlannerBot again.

PlannerBot: "Apologies. I meant the 'Green Pastures' estate."

I called Green Pastures. Their quote: $12,000.

! ALERT: AI CANNOT NEGOTIATE OR READ 2025 PDF PRICE SHEETS !

Workaround: I had to feed PDF pricing sheets from 10 actual venues into the context window. Once it had real data, it found a loophole: A City Park Pavilion for $200.

> DAY 2: THE AESTHETIC

StyleBot wanted a theme.

StyleBot: "Theme: 'Cyber-Nature'. Neon lights intertwined with raw moss and ferns. Color palette: Electric Blue, Moss Green, and Charcoal."

It generated a shopping list for Amazon/AliExpress.

Decor Budget ($500)

  • 100ft LED Neon Strip ($45)
  • 20lbs Preserved Moss ($120)
  • Biodegradable Glitter ($30)
  • Fog Machine ($50)

I visualized this. It would either look like a high-end art installation or a swamp rave. I engaged CommsBot to ask florists if they could work with "Cyber-Nature."

> DAY 3: THE VENDOR EMAILS

CommsBot drafted emails to caterers. It was surprisingly good.

The response rate was 80%. Humans reply well to polite, specific emails. We secured a taco truck for $800.

> THE FINAL BUDGET BREAKDOWN

Item AI Estimate Real Cost Notes
Venue (City Park) $200 $250 Forgot cleaning fee
Food (Taco Truck) $750 $900 Forgot gratuity
Alcohol (BYOB Permit) $300 $450 Underestimated consumption
Decor (DIY Moss) $400 $400 AliExpress pricing accurate
Music (Spotify Playlist) $0 $0 AI curated playlist
Photography (Student) $500 $800 Hard to find cheap talent
TOTAL $2,150 $2,800 + $2k buffer Still under $5k!

> THE CONCLUSION

Can AI plan a wedding? Yes, but only the boring parts.

It is excellent at drafting emails, comparing spreadsheets, and generating checklists. It is horrible at knowing if a venue is "vibey" or if "Cyber-Swamp" is a good theme.

The biggest failure? Empathy. When I told PlannerBot I was stressed, it said: " Stress is inefficient. Please focus on the napkin color selection."

If you want to save money, use AI as your secretary. But don't let it pick the dress.
