DEEP DIVE
A year ago, I was drowning in AI tools. Every week a new LLM (large language model) would drop and I kept asking the same questions:
“Is this better than ChatGPT?”
“Will this actually help me grow my business?”
“Am I wasting time switching models again?”
So, I decided to go all in.
I tested everything GPT-4o, Claude, Gemini, Grok, DeepSeek, and a few secret ones. Some were insanely helpful. Some were pure hype. Some cost more than they were worth.
Let me break it down for you. This is not tech theory, this is how I use these tools to save money, make money, and move faster in business.
LLM Tier Breakdown (With Real-World Use)
💎 S Tier – Game-Changers
1. Claude 3.5 (Anthropic)
Best for: Writing, coding, creating diagrams, coaching workflows
Why it matters: I use it with Lindy.ai to automate team coaching. Claude tracks my team’s top tasks and even builds leaderboards. It’s smart, fast, and reliable.
➡️ Verdict: If I had to pick one LLM for daily operations, this would be it.
2. Gemini (Google)
Best for: Developers, engineers, and product builders
Why it matters: My dev team switched from GPT to Gemini for coding. It generates clean, fast, optimized code. Bonus: NotebookLM (built on Gemini) turns long PDFs into bite-sized podcasts.
➡️ Verdict: Your coding and research sidekick.
3. ChatGPT-o3 (Classic)
Best for: Business analysis, quick graphs, strategic insights
Why it matters: I dumped my QuickBooks data into GPT-3 and got a full revenue retention analysis within minutes.
➡️ Verdict: Don’t sleep on the OG. Still packs power.
✅ A Tier – Reliable Workhorses
4. ChatGPT-4o
Best for: Strategy, memory-based tasks, creative assistance
Why it matters: It remembers conversations and builds on your progress. Created a 12-page business plan for an e-commerce flower shop idea in one session.
➡️ Verdict: Feels like a smart partner who grows with you.
5. Grok (X/Elon Musk)
Best for: Real-time info, market updates, Twitter summarizing
Why it matters: See a complex tweet? Click “Grok” and get a simple explanation. It’s like a personal news analyst for high-signal Twitter threads.
➡️ Verdict: Perfect if you live on X and crave fast insights.
6. Manus AI (built on Claude)
Best for: High-speed content creation
Why it matters: It learned my writing guidelines and then wrote 21 blog posts in 30 minutes good ones.
➡️ Verdict: A creative machine that saves hours.

7. DeepSeek (China)
Best for: Budget projects
Why it matters: It's open-source and extremely cheap. Great for reducing token costs if you're building something that needs scale.
➡️ Verdict: Good for backend-heavy work on a budget.
8. Notebook LM
Best for: Digesting long-form content
Why it matters: Upload a 42-page PDF or 4-hour video, and it creates an 8-minute podcast summary.
➡️ Verdict: A content digestion tool, not a core LLM.
🟠 C Tier – Early, Clunky, or Overhyped
9. ChatGPT Operator
Best for: Simple agent tasks
Why it matters: Follows basic instructions, like finding prospects or reviewing documentation. Still needs hand-holding.
➡️ Verdict: Like a virtual intern—can help, but don’t rely on it yet.
10. Meta’s LLaMA (via WhatsApp, Instagram, etc.)
Best for: Casual queries
Why it matters: It's around, but never quite gets it right. I default back to Claude or GPT.
➡️ Verdict: Not serious enough for pro use yet.
