Which AI Should You Use?
Pick your LLM carefully
Are you looking to get in front of 15,000+ AI readers? Sponsor this newsletter.
It started with confusion. A client wanted a full AI marketing plan. I opened ChatGPT.
But it didn’t hit. Switched to Claude. Too vague. Tried Gemini. Slow and clunky.
Each model felt like a “maybe.”
I realized I had no system—just random trial-and-error based on hype and habit. And it was costing me time, quality, and clarity.
That’s when I sat down, made coffee, and created my own map. Not a list of what each LLM can do.
But a cheat sheet of when to use each one—based on real work tasks.
Today, I’m sharing that map with you. I didn’t expect much. Now I can’t stop using it.

DEEP DIVE
The Quick & Dirty Guide to Picking the Right AI Model (LLM)
Let’s say you're juggling these 5 tasks this week:
Writing a newsletter
Coding an automation script
Researching productivity hacks
Generating visuals for a landing page
Crafting a viral Twitter thread
Here’s how I’d match the model to the task:
Best For: General-purpose writing, ideation, summarizing, and automation
Why: Feels like your smartest teammate. It’s great at structure, memory, and logic.
Use Case: Writing blog posts, emails, outlines, and code snippets that need context from previous chats.
Bonus Tip: Use the Memory feature to teach it your tone, goals, and process. It’ll remember you.
2. Claude Opus
Best For: Thoughtful writing, long context reasoning, and human-like tone
Why: It understands nuance like no other. If you're writing threads, essays, or philosophical takes—this is it.
Use Case: Deep journaling, client communication drafts, or explaining complex topics in a kind voice.
Pro Insight: Claude is best for tasks where empathy and clarity matter more than speed.
3. Gemini Pro
Best For: Large document digestion, visual and tabular analysis
Why: It handles entire PDFs, Excel files, and images. Very Google-native.
Use Case: Studying eBooks, analyzing long-form research, comparing tools, or planning from spreadsheets.
Quick Trick: Drop in your eBook + ask: “Give me the 5 biggest takeaways with examples.”

Final Words
The model you choose isn’t about which one’s “the best.”
It’s about which one’s the best for the job.
Think of it like hiring team members.
Some write.
Some research.
Some sketch.
Some challenge your ideas.
The real flex? Knowing when to bring in which one.
Start with one model this week. Use it for one specific task.
Then watch how your workflow changes.
