Mind map for YouTube video: ChatGPT 5 explained in 7 minutes

ChatGPT 5 explained in 7 minutes

TL;DR The video introduces ChatGPT 5 as a significant advancement, akin to having "PhD experts in your pocket," highlighting its three main versions: GPT-5, GPT-5 Thinking, and the $200/month GPT-5 Pro. A key revelation is OpenAI's default ChatGPT interface restricts GPT-5's context window to 32K tokens, despite its actual capacity being 400,000, limiting its utility for large documents. The presenter promotes Vectal.AI as a solution, offering the full 400K context window for free or unlimited access at a fraction of OpenAI's Pro cost. GPT-5 demonstrates impressive capabilities like generating visual books and attempting to build complex web apps, though the latter showed limitations. The video provides crucial pro tips for maximizing GPT-5's performance, including prioritizing "Thinking" mode, using "think hard" prompts, leveraging new "Study," "Agent," and "Deep Research" modes, and utilizing "Add to Memory" and "Projects" features. While GPT-5 is an improvement over GPT-4, it's deemed "nowhere near AGI," especially for coding, where other models like Claude Code or Gemini 2.5 Pro might be superior.

🧠 ChatGPT 5: A Comprehensive Overview & Pro Tips

πŸ”‘ Key Features & Model Tiers

  • Significance:
    • Biggest release since ChatGPT's creation in 2022.
    • Described by OpenAI as "like having a team of PhD experts in your pocket."
  • Available Models within ChatGPT:
    • GPT-5 (Default)
    • GPT-5 Thinking
    • GPT-5 Pro
      • Cost: $200 per month (from OpenAI)
  • Automatic Model Router:
    • Built-in system that selects the appropriate LLM based on request complexity.
    • Simpler requests: Routed to faster models for quick answers.
    • More complex questions: Routed to powerful versions like Thinking mode.

πŸ”‘ Core Limitations & Solutions

  • Major Problem: Context Window Discrepancy:
    • OpenAI's ChatGPT interface limits GPT-5 to a 32K token context window.
    • Actual GPT-5 capacity: 400,000 tokens.
    • Implication: Prevents pasting large books, PDFs, documents, or having long conversations effectively.
  • Solution: Vectal.AI:
    • Offers GPT-5 with the full 400,000 context window.
    • Access:
      • Completely free to try.
      • Vectal Pro offers unlimited GPT-5 for 10 times less than OpenAI's $200/month plan.
      • Includes access to other cutting-edge AI models.
    • Actionable:
      • Go to vectal.ai and sign up for full context access.

πŸ”‘ Capabilities Demonstrated

  • Web App Building (Canvas Integration):
    • One of the biggest, less-talked-about updates.
    • Can build full web apps directly within ChatGPT.
    • Example 1: Visual Book Generation:
      • Prompt: "Generate a visual book that will showcase the fundamental concepts needed to understand AI and ML."
      • Result: Successfully created a visual book with custom-coded illustrations and interactive flipping pages.
      • Benefit: Significantly faster than manual creation of presentations/graphs.
    • Example 2: Interactive 3D Web App (GPT-5 Pro attempt):
      • Prompt: "Build a full stack web app in canvas that shows multiple 3D geometric objects with several sliders allowing you to change the quantity and scale of those objects."
      • Result:
        • Took 6 minutes 13 seconds to run.
        • Did not use canvas directly in the initial output.
        • Required manual copying of code to a new chat and explicit canvas trigger.
        • Final attempt to run resulted in an error ("an error occurred. We're trying to run 3D multi-object canvas.").

πŸ”‘ Pro Tips for Optimal GPT-5 Use

  • 1. Model Selection & Prompting:
    • Prioritize GPT-5 Thinking:
      • Default GPT-5 minimal (via router) performs at 44 on benchmarks.
      • GPT-5 Thinking performs at 68 on benchmarks (close to best in world).
    • Use "think hard" in prompts:
      • Directly impacts how often Thinking mode gets triggered by the model router.
  • 2. Specialized Modes (via + icon before prompt):
    • Study Mode:
      • Turns ChatGPT into a personal tutor for learning any concept.
      • Actionable:
        • Click + icon -> select study and learn.
    • Agent Mode:
      • Allows ChatGPT to control certain websites and perform small actions.
    • Deep Research:
      • Excellent for thorough research on topics.
      • Can browse 20-30 different websites and create detailed reports.
  • 3. Workflow Enhancements:
    • Add to Memory:
      • Tell ChatGPT add to memory to remember specific information across conversations (e.g., city, response style).
      • Actionable:
        • Use the phrase add to memory for persistent context.
    • Projects Feature (Left Sidebar):
      • Good for managing different areas of life.
      • Allows setting a custom system prompt for each project, avoiding repetition.
      • Actionable:
        • Click on sidebar -> new project -> give name & system prompt.
  • 4. Pro User Settings:
    • Show Legacy Models:
      • Allows access to older models that were previously removed.
      • Actionable:
        • Click account -> settings -> toggle show legacy models (if paying user).
        • Access them via the model selector.

πŸ”‘ Overall Assessment (Coding)

  • Comparison to Previous Versions:
    • GPT-5 is "certainly better than the previous version, GBD4."
  • Limitations:
    • Still "nowhere near AGI" (Artificial General Intelligence).
    • For coding: There are "much better AI models."
  • Potential Alternatives for Coding:
    • Claude Code
    • Grok 4
    • Gemini 2.5 Pro
  • Call to Action:
    • Comment "part two" if interested in a video comparing GPT-5 to these alternatives specifically for software development.
