Choosing the right ChatGPT model has been downright confusing.
Until now.
OpenAI have finally cleared things up with their new model selection guide.
I took it one step further and created a version specifically for marketers.
Here’s how to pick the right model, every time:
If you need everyday content creation → GPT-4o
For emails, summaries, captions, proofreading. It’s fast, cheap, and reliable.
If you need emotionally resonant copywriting → GPT-4.5
Use it when tone matters. Think brand voice, storytelling, high-emotion posts, and customer comms.
If you need fast technical answers → o4-mini
Need to pull KPIs, write formulas, or debug code snippets fast? This one’s built for it.
If you need detailed technical analysis → o4-mini-high
Perfect for digging into SEO audits, funnels, or A/B test results. Less fluff, more signal.
If you need complex marketing strategy → o3
Go here for campaign planning, competitor analysis, or full GTM builds. Handles multi-step thinking better than most.
If you need high-stakes analytical work → o1 Pro Mode
Enterprise-level decks. Global expansion plans. Strategic pivots. When it really matters, don’t risk a lightweight model.
Here’s the full cheat sheet including sample prompts:
Pick the right model. Get better results. Waste less time.
Happy prompting!
