Not all LLMs are built the same.

Here’s the ultimate cheat sheet:

→ GPT = content & comms
→ Gemini = vision + audio
→ Mistral = speed & edge
→ DeepSeek = math + logic

How to master each (fast): 👇
1. BERT - The Reader

Made by Google (2018), BERT reads text in both directions.

It understands context deeply, making it great for:

→ Search engines
→ Sentiment analysis
→ Question answering

It’s the foundation of “understanding” in AI. Image
2. GPT - The Writer

Created by OpenAI, GPT predicts the next word in a sentence.

It’s decoder-only and excels at:

→ Generating fluent text
→ Storytelling
→ Prompt-based creativity

Think: ChatGPT, but trained at massive scale.
3. LLaMA - The Open Challenger

Meta’s open-source alternative to GPT.

Uses clever tricks (SwiGLU, RoPE) to rival models 10x its size.

→ Smaller, cheaper, surprisingly strong
→ Fueled massive community development

The underdog with real bite. Image

4. PaLM - The Few-Shot Master

Built by Google, PaLM is huge (540B) and optimized for:

→ Few-shot tasks
→ Reasoning
→ Multilingual performance

It powers Bard and Workspace AI. Smart, scalable, and serious. Image
Image
5. Gemini - The Multimodal Beast

The evolution of PaLM.

Gemini understands text, images, code, and audio all in one model.

→ Massive context windows
→ Sparse expert layers
→ Enterprise-ready and phone-capable

This is Google's bet on the AI future.
6. Mistral - The Efficient Rebel

Small but mighty.

Mistral 7B beats much larger models using:

→ Grouped-query attention
→ Sliding windows
→ Sparse MoE in Mixtral

Open, fast, and crushing benchmarks with fewer parameters.
7. DeepSeek - The Reasoning Genius

From China’s High-Flyer AI.

Uses a Mixture-of-Experts (MoE) setup with 670B total params.

Only ~37B active per response = low cost, high IQ.

Excels at logic, math, multilingual tasks.

Like GPT-4’s smarter cousin.
LLMs aren’t one-size-fits-all.

Know what you’re building and choose the right model:

→ Reader? BERT
→ Writer? GPT
→ Open? LLaMA
→ Cheap + fast? Mistral
→ Multimodal? Gemini
→ Few-shot? PaLM
→ Reasoning? DeepSeek
90% of customers expect instant replies.

Most businesses? Still responding days later.

WARNING: After you use these prompts, you’ll never write the same way again.

This might be the most useful thing I’ve shared all year.

Here are 12 prompts turn any LLM into a full writing studio that works harder than you do:
1/ The “Voice Injection” Prompt

Gets the model to fully absorb your writing style.

“Here are 5 samples of my writing. Extract my tone, pacing, sentence structure, and emotional signatures. Confirm when my ‘voice profile’ is ready.”

This sets the foundation. Image
2/ The “Idea Engine” Prompt

Infinite hooks, titles, and angles.

“Generate 20 content ideas that could go viral in my niche. Mix curiosity, tension, and contrarian angles. No clichés.”

It’s like having a strategy intern. Image

If you’re not using AI to train your psychological instincts, you’re behind.
These 7 Greene-based prompts will change that.

Here’s how to run them 👇 Image
1. The Power Dynamics Decoder (Law of Awareness)

"Break down the power dynamics between me and [PERSON/GROUP] in the context of [SITUATION]. Identify: 1) What they want, 2) What they fear, 3) Unspoken motives, 4) Leverage points I am missing. Give me a clear map of the terrain so I don't walk in blind."
2. The Strategic Silence Simulator (Law of Patience)

"I tend to respond too quickly in [CONVERSATION TYPE]. Train me to use strategic silence like Robert Greene teaches. Show me: 1) When silence increases my influence, 2) What phrases I can use to slow a conversation down, 3) How to create an aura of control. Build a practice scenario with scripts."

I shouldn’t share this.

These 10 Perplexity prompts are the ones founders pass around quietly, the ones that turn vague curiosity into an actual SaaS concept overnight.

(Bookmark this for later) Image
1. SaaS Opportunity Mapper

"Analyze unmet needs in the niche: [ENTER NICHE]. Identify 5 urgent, high-value problems and propose SaaS solutions with target users, workflows, and revenue models."
2. Pain-Point Deep Dive

"Break down the daily workflow of someone in the role: [ENTER ROLE]. Surface the biggest inefficiencies and recommend SaaS ideas that automate or remove those steps." Image

🚨 Stop using ChatGPT and Perplexity for research.

I just spent 48 hours testing Gemini 3.0 and holy shit... it's not even close.

This thing finds connections that other models completely miss.

Here are 5 powerful ways to use Gemini 3.0 for research:
1. Investment & Startup Research

Want to invest in a startup or analyze potential unicorns? Use DeepSearch to uncover financial health, investor trends, and market positioning.

Try this prompt:

"Analyze the startup landscape in [industry]. Identify promising startups, their funding rounds, valuation trends, and investor interest. Provide actionable insights."
2. Business Research Task

Before launching a product, understanding your competition is crucial. Grok can analyze business models, pricing, and key differentiators.

Try this prompt:

"Analyze the top 5 competitors in [industry]. Focus on their pricing, revenue models, strengths, and weaknesses. Provide insights on how a new business can compete effectively."

Holy shit… the consulting industry is in trouble

You don’t need a $300k firm anymore.

Gemini 3.0 Pro can now run full competitive market analysis better and faster.

Here are the 3 mega-prompts I use to replicate McKinsey-level insights for free:
We use these 3 mega prompts for different tasks:

1/ The Consultant Framework

Prompt: "You are a world-class strategy consultant trained by McKinsey, BCG, and Bain. Act as if you were hired to provide a $300,000 strategic analysis for a client in the [INDUSTRY] sector.

Here is your mission:

1. Analyze the current state of the [INDUSTRY] market.
2. Identify key trends, emerging threats, and disruptive innovations.
3. Map out the top 3-5 competitors and benchmark their business models, strengths, weaknesses, pricing, distribution, and brand positioning.
4. Use frameworks like SWOT, Porter’s Five Forces, and strategic value chain analysis to assess risks and opportunities.
5. Provide a one-page strategic brief with actionable insights and recommendations for a hypothetical company entering or growing in this space.

Output everything in concise bullet points or tables. Make it structured and ready to paste into slides. Think like a McKinsey partner preparing for a C-suite meeting.

Industry: [INSERT INDUSTRY OR MARKET HERE]"
2/ The Competitive Deep Dive

Prompt: "Act like a senior consultant preparing a competitive market analysis deck for a $10B strategy client.

Your task:
- Analyze the overall landscape of the [INDUSTRY] industry.
- Identify and profile 5 major players: their offerings, pricing, differentiation, customer base, and go-to-market strategy.
- Use comparison matrices to highlight competitive positioning.
- Reveal where gaps or white space exist in the market.
- Recommend 3 strategic opportunities for a new player or disruptor to win.

Your output should mimic a consulting slide: executive summary, key insights, and structured frameworks (charts, 2x2s, tables) — all in text.

Industry: [INSERT MARKET NAME OR NICHE]"
