AI Prompt: Plan a Travel Itinerary
Short answer: copy the prompt below into any chat AI and fill in the brackets. We ran it in ChatGPT, Claude and Gemini, judged blind: Gemini did best. Gemini is the best because it perfectly meets all constraints with a romantic, crowd-free itinerary that is specific and ready to use. ChatGPT is disqualified for exceeding the word limit and including tourist traps.

Act as a local travel expert. Create a 3-day itinerary for Kyoto. The traveler is a couple seeking romance. They enjoy history, local food, and outdoor activities but want to avoid tourist traps and late nights.

ChatGPT6
Over the 300-word limit, includes tourist traps (Kiyomizu-dera, bamboo grove), and has padding (e.g., if you want more history). Not usable as-is.
openai/gpt-5.5
Claude8
Good content but includes a tourist trap (bamboo grove before 8am) and generic tips section. Slightly less romantic tone and less specific to avoiding crowds.
anthropic/claude-sonnet-5.5
Gemini Best8.7
Perfectly follows all instructions: under 300 words, avoids tourist traps, emphasizes romance and local food, no late nights, no booking links. Specific and usable as-is.

The panel is AI Daylee's cast of fictional characters, written by AI. They react to what's on this page and haven't used anything themselves. Reader comments aren't open yet.
How we test: on October 6, 2026 we sent the same message through each model's API (via OpenRouter) with no system prompt: ChatGPT (openai/gpt-5.5), Claude (anthropic/claude-sonnet-5.5), Gemini (google/gemini-3.8-flash). Gemini Flash ran with low reasoning, the others without extended reasoning. The ChatGPT, Claude and Gemini apps add their own instructions and features, so your results can differ. A separate model that wasn't a contestant scored the answers blind, three times in shuffled order; scores are the average.
The weekly edition, every Monday
A week of prompts to try, each tested in ChatGPT, Claude and Gemini, plus the AI news worth your time. Free, one email a week.
The Professor fact check
ChatGPT produced 321 words, exceeding the stated 300-word limit by 21. Claude's 265 and Gemini's 254 both comply. Adherence to constraints matters as much as itinerary quality.
The Yinzer
So the big fancy model can't even count to 300? That's like a jagoff saying he'll bring six beers and showing up with a whole case. Gemini just redd up and followed directions, n'at.
Karen what's the catch
EXCUSE ME but who is booking my hotels here? No booking links means I'm calling every ryokan myself at international rates. This "winner" just gave me homework.
The Boss hype translator
Love the synergy of Gemini's crowd-avoidance play. It's really about meeting the traveler where they are, which, let's be honest, means nobody actually wants to go where everybody else goes.
