Guide to picking the right ChatGPT model

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!
