Example Prompts
Summarize meeting notes into key action items.
Draft a follow-up email after a project kickoff.
Proof read my report.
Brainstorm a launch plan in real time—feel free to upload sketches or screenshots.
GPT-4.5
Ideal for creative tasks: Emotional intelligence, clear communication, creativity, and a more collaborative, intuitive approach to brainstorming.
Example Prompts
Create an engaging LinkedIn post about AI trends.
Write a product description for a new feature launch.
Develop a customer apology letter with an empathetic tone.
OpenAI o4-mini
Fast technical tasks: Quick STEM-related queries, programming, visual reasoning.
Example Prompts
Extract key data points from a CSV file.
Provide a quick summary of a scientific article.
Quick-fix this Python traceback for me.
