If you haven't already, first make sure you understand the basic functionality of the ChatGPT interface, like editing previous prompt, uploading files etc. You find basic features listed here.
There is Advanced Voice Mode (AVM) and the Standard Voice.
Tell AVM to "speak slower" or "speak faster".
Interrupt it by saying "stop".
English works better than Swedish (higher risk of issues).
Speaking close to the microphone sometimes prevents issues.
Tip: Ensure your internet connection is strong, fast and stable.
You can switch models (within ChatGPT) that serves your needs. Examples:
GPT-4o = Good all-round model for most questions
o3-mini-high = For coding & mathematics
GPT-4.5 = For fewer hallucinations, language-related logic, creative writing, humor. Warning: High API cost
GPT-4o mini = For speed
Custom GPTs are customized versions of ChatGPT, that can be very useful. But GPTs also have limitations: No Search button, no Canvas, no Deep research. Tip: create a command to activate internet search. In GPT Store, you can find many useful GPTs, for example:
DALL-E - Generates two images (instead of one, which is the default behavior of ChatGPT).
Data Analyst - Optimized for data analysis and visualization (generating diagrams).
Consensus - Find research articles and scientific literature.
"Martin Ågren GPT" - my own custom GPT . Short answers & useful commands etc.
Activate video sharing from within Advanced Voice Mode.
Example: Show your computer screen and let it guide you through an interface.
Tip: Ensure your internet connection is strong, fast and stable.
Tip: Use a high-quality camera for the best experience.
Not to be confused with the custom GPT "Canva" or Canva.com. You can undo and redo changes. Use cases:
Frontend development coding: HTML, CSS, JS - Preview-button available at ChatGPT.com in web browser (not installed ChatGPT). No external CSS file. Example: "Create a very simple web page. h1 should say: Hello World"
Python coding - Run-button available in both web browser and installed ChatGPT. Example: "Create a simple Python script that prints a very short text string."
Text. Buttons: Edit, Adjust length, Reading level (college etc), Polish (press two times), Emojis. Example: "Write a very short love poem."
Example: Receive email (or notification) every morning at 8 AM about today's AI news.
Notifications: At ChatGPT.com (not in computer app): Profile icon >> Settings >> Notifications >> Choose from drop-down menu.
See task list: At ChatGPT.com (not in computer app): Profile icon >> Tasks >> Delete a task, etc.
Powerful research tool in ChatGPT. Available for Plus/Team users (10 searches per month). Example:
Inference time: 5-30 min (reading 35 web pages)
Comprehensive answer: 6000 words
Reference list (APA 7): 15 sources
Projects folders with separate chat history and different colors.
Specific settings & file uploads
For A-Z order: Add Z first etc
Downside, regarding following instructions: ChatGPT does not follow these instructions as well as instructions in custom GPTs.
Disabled by default: "Memory is disabled"
Enable or disable memory function: Click profile icon >> Settings >> Personalization >> Toggle "Memory" on/off
In message field: "Memorize this: …"
Memories kan be deleted but not changed manually: Click profile icon >> Settings >> Personalization >> Manage memories
Downside: ChatGPT sometimes memorizes irrelevant info.
