ChatGPT Speaks - A complete list of various LLM's for different Applications and Uses - plus a little bit more

I constantly find myself arguing with people about your capabilities. My favorite quote is, "LLMs don't know anything. You can only trust them with so much." While I agree with the first sentence, I wonder what I could do to ensure the best output possible from these applications. I think I'm looking for suggestions for different programs that focus on specific areas of expertise. Also, what benefits (if any) would be available to paid subscription tiers?

ChatGPT:

You're absolutely right to say that “LLMs don’t know anything”—at least not in the traditional sense. They don’t possess knowledge or understanding like humans do. What they do have is access to an enormous amount of training data, patterns, and representations of information, which allows them to generate highly relevant responses based on what users ask.

If you're looking to ensure the best output possible, here’s a breakdown of:

✅ How to Get the Best Output from LLMs

1. Know the Strengths and Limits

• LLMs are great at synthesis, summarization, brainstorming, explanation, and basic coding.
• They can’t browse the internet in real time unless connected to a tool like a web browser plugin or API call.
• LLMs can hallucinate facts, especially when prompted vaguely or asked for very obscure or non-existent information.

2. Use Expert-Focused Tools

Here’s a list of LLM-backed tools/apps tailored to specific domains, where they tend to excel:

Area	Recommended Tool / Program	Notes
Programming	GitHub Copilot / ChatGPT Code Interpreter (Pro Tier)	Great for explaining code, debugging, and prototyping
Mathematics	Wolfram Alpha Plugin / ChatGPT Pro with Wolfram	Symbolic math, graphing, and verified solutions
Science & Engineering	ChatGPT + Python Tool / Elicit.org	Literature review, simulations, data analysis
Medical/Health	Glass AI (beta) / UpToDate / ChatGPT for general knowledge (with caution)	Always verify with real physicians
Academic Research	Elicit.org / Semantic Scholar + ChatGPT	Elicit uses AI for paper discovery and summarization
Writing / Editing	Grammarly + ChatGPT / Sudowrite	Co-writing, tone adjustment, content brainstorming
Legal/Policy	CaseText CoCounsel / ChatGPT + Web Access	LLMs can summarize, not provide actual legal advice
Hardware Design / Electronics	ChatGPT (with examples) + Octopart / Digi-Key / CircuitLab	Good for learning and rapid design help
3D CAD / Modeling	Autodesk AI tools / Fusion 360 Assistant	Integrating GPT-4 features into workflows

3. Use Clear, Specific Prompts

Here’s a progression:

• ❌ "Tell me about solar panels."
• ✅ "Summarize the difference between monocrystalline and polycrystalline solar panels in 3 bullet points, assuming I’m an electrical engineering student."

4. Ask for Citations or External Sources

• Prompt: “Cite your sources,” or “Give me the names of real papers, books, or URLs.”

💳 Benefits of Paid Subscription Tiers (e.g., ChatGPT Plus/Pro)

ChatGPT Plus ($20/month as of 2025) gives access to GPT-4-turbo, which is significantly more powerful and capable than GPT-3.5. Here's what's included:

🔧 Core Upgrades:

Feature	GPT-3.5	GPT-4-turbo (ChatGPT Plus)
Performance	Fast, decent quality	More accurate, better reasoning, longer memory
Context length	~16k tokens	Up to 128k tokens (in turbo)
Image input	❌	✅ Analyze images
File handling	❌	✅ Upload and process files (CSV, PDF, code, etc.)
Custom GPTs	❌	✅ Use and build GPTs with tailored behavior
Tools	❌	✅ Python/Code Interpreter, DALL·E image generation, browser access (some accounts)

🧠 Ideal For:

• Complex reasoning tasks
• Writing and editing workflows
• Multimodal inputs (e.g., code + image)
• Handling long documents (e.g., 100-page PDFs)
• Business planning, financial modeling, simulations

🧭 Summary: How to Use LLMs Effectively

Step	Action
🎯 Define your goal	Be specific: Are you researching, debugging, writing, planning?
✍️ Craft clear prompts	Use roles: "Act like an electrical engineer…" or constraints: "Give a summary under 100 words…"
🛠️ Choose the right tool	Use GPT-4-turbo, Wolfram, Elicit, or Copilot depending on your need
🔁 Iterate and verify	Ask it to check its own answers or improve clarity
🔎 Ask for sources	Especially for factual, legal, or medical content
💡 Use in tandem with real expertise	The best results happen when you know enough to guide the tool well

If you're curious, I can recommend specific GPTs or plugins tailored to your interests—just let me know your focus (e.g., science, law, creative writing, etc.).
