What This Is

Step 6 is where you stop being a "ChatGPT user" and become an "AI user." Each major model has distinct strengths: ChatGPT for breadth and plugins, Claude for writing and long documents, Gemini for Google integration and current info, Perplexity for cited research, Grok for real-time social data. Mastering multi-model means picking the right tool for each job—not forcing one tool to do everything.

Why It Matters

Most people use whatever AI they started with—usually ChatGPT—for everything. That's like owning only a hammer. Step 6 users get better results because they match tool to task. Need deep analysis of a 100-page PDF? Claude. Need real-time search with sources? Perplexity. Need to analyze a 2-hour video? Gemini. The difference in output quality is dramatic when you use the right model.

The Major Models at a Glance

Model Best For Key Strength When to Choose
ChatGPT General tasks, Custom GPTs, plugins, daily driver Ecosystem: Memory, GPTs, integrations, image generation Default choice; when you need plugins or Custom GPTs
Claude Writing, long documents, nuanced analysis, coding Context window: 200K tokens—can read entire books/codebases Long documents, better writing quality, thoughtful analysis
Gemini Multimodal tasks, Google integration, video/image analysis, coding Multimodal: Native image/video/audio understanding; 1M+ token context Analyzing videos/images, Google Workspace, very long documents, coding

How To Do It

1.

Set Up All Models

Create accounts for ChatGPT, Claude, Gemini, and Perplexity. Free tiers work for testing; upgrade your primary 1-2.

2.

Run the Same Task Across Models

Give the same prompt to 2-3 models. Compare outputs. Notice what each does better. This builds intuition.

3.

Match Tool to Task Type

Before starting any AI task, spend 5 seconds asking: "Which model is best for this?" Use the framework above.

4.

Build Your Selection Guide

Document your own preferences. Which models work best for your specific tasks? Create your personal cheat sheet.

Real-World Examples

Triangulating Important Research

Ran the same market research query through ChatGPT, Claude, and Perplexity. Each surfaced different insights. Combined the best of all three for a comprehensive report with verified sources.

Long Document Analysis

Needed to analyze a 75-page contract. ChatGPT couldn't hold the whole thing. Switched to Claude, uploaded the full PDF, got detailed analysis with specific clause references.

Video Analysis at Scale

Needed to review a 90-minute recorded presentation for key takeaways. Uploaded to Gemini, asked for timestamps of main topics and a summary of each section. Got a detailed breakdown in minutes.

Pro Tips

For critical decisions, triangulate: run the same query across 3 models and compare results.
Claude generally writes better prose; ChatGPT is more versatile; Perplexity is most transparent.
Gemini's 1M+ token context window is largest—use it for massive documents or video analysis.
Perplexity Pro gives you access to multiple models (GPT-4, Claude) within one interface.
Don't pay for all of them—pick 2 to upgrade based on your most common tasks.
When a model struggles, don't keep retrying—switch models instead.
Key Insight

"Step 6 is the course midpoint—and a crucial mindset shift. You stop asking 'How do I get ChatGPT to do this?' and start asking 'Which AI does this best?' That question alone separates casual users from power users."
