The Product Manager's AI Model Selection Guide: Which Tool for Which Task? 🤖
I've spent $4,000+ testing every AI model so you don't have to."
Here's the brutal truth: Most product managers are still guessing which AI tool to use for what task.
I see it every day. PMs jumping between ChatGPT, Claude, and Gemini without any strategy. Using Opus for quick tasks that Flash could handle in seconds. Burning budget on premium models when the free tier would work perfectly.
Let me save you 18 months of expensive trial and error. 💸
The Problem Every PM Faces 🎯
You know AI can help with PRDs, research, and roadmaps. But which model? Which version? For which specific task?
I've been there. Started with ChatGPT for everything. Then discovered Claude's analytical superpowers. Got seduced by Gemini's speed. Almost went broke testing every new model that launched.
Here's what I learned: The best AI strategy isn't about finding one perfect tool. It's about building the right toolkit.
Your AI Toolkit Breakdown 📊
After 18 months and way too much money spent, here's exactly what each tool excels at:
Key Model Recommendations by Provider
ChatGPT wins the long game for one simple reason: it actually remembers you. 🧠
While other models reset every conversation, ChatGPT builds context over weeks and months. It learns your work style, remembers your frameworks, and adapts to your preferences. No more re-explaining your methodology every session.
But here's where each model shines:
Claude 3.5 Sonnet → Your go-to for deep analysis and structured thinking
Gemini 2.5 Flash → Lightning fast and crazy cheap for high-volume work
Grok 3.0 → Real-time info and uncensored brainstorming
Perplexity Pro → Research powerhouse with proper citations
Think of it this way: ChatGPT is your main work partner. The others? Specialized consultants you call when you need their superpowers.

Additional Resource - context windows
If you’re still guessing which model is best for your task, this chart is your wake-up call: context window size matters—a lot. Gemini’s monstrous 2M-token capacity lets you process entire books, while Claude and ChatGPT dominate for deep dives and daily work with context windows that fit real project workflows. Don’t just chase the biggest number; match your use case to the right AI—because picking the right model for the job is where product managers start beating the guessers.
