Wednesday morning I saw OpenAI dropped new models again — my first reaction: "Here we go again."

Honestly, every time I see "new major model released" I get a headache — GPT-3.5, 4, 4o, o1... I can't even keep the names straight, let alone figure out which one fits my work. But this time they dropped two, and the positioning is unusually clear: one fast, one deep. The biggest lesson I've learned running my side hustle these past few years: before any tool upgrade, figure out "what do I actually use this for?" Otherwise the money's gone, the time's wasted, and the work is still on your plate.

So what are these two, and who's already using them?

Quick rundown — this is the non-coder version I can actually understand:

The fast one — cheap, snappy responses, great if you're pumping out hundreds of short posts or replying to dozens of emails a day. My cousin Xiao Chen runs a Xiaohongshu fashion account; on this version she could probably draft 30 extra post ideas in one evening.

The deep one — slower, pricier, but better for contracts, deep research, long-form writing. My friend Lao Zhou does independent consulting; yesterday he ran a 20-page industry report through it and told me he finally didn't have to stay up crunching data himself.

I can't make heads or tails of the specific technical parameters, but the pitch this round is: daily work is cheaper, deep tasks come out higher quality. Sounds like corporate marketing, but the pricing actually backs it up.

What does it cost to try this yourself today?

💰 Money: New users usually get free credits (depends on your account); the deep version might require payment. If you're still grinding on GPT-4o for daily work, the new setup is probably cheaper than what you're paying now. I've been on the Plus subscription forever — this round I'm thinking of switching.

⏱️ Time: Log into your account (2 min), switch models (1 min), figure out which one fits your actual work (30 min). Half an hour, done.

🎯 Technical barrier: If you can send a WeChat message, you can use this. No code, no weird setup, no API keys.

👉 First step: Open your usual AI chat page (web or app), check the model dropdown for the two new entries. Don't see them? Your account hasn't been rolled out yet — check back in a few days.

Should you bother? Depends on where you are.

🌱 Just starting out (0 clients or just beginning to find them): If you haven't even gotten comfortable with your current GPT yet, please don't chase this. I've been there — chased the new thing halfway, ended up with half-finished work and an idle account. This week, do what you were already doing. New tools can wait until you hit a real bottleneck.

🌿 Already have 1-2 stable clients: Worth spending half an hour checking if the fast model fits your high-frequency tasks. If you're replying to client emails and writing daily reports every day, it might genuinely save you money. The deep one — sit tight unless you've got a heavy task in front of you.

🌳 Scaling up (3+ person team or making 10K+ RMB/month): You probably should have been splitting tasks across models ages ago. This release gives you a clean excuse to do an internal audit — which tasks go on which model, which stay on the old one. Spend an afternoon thinking this through; that's worth more than chasing any new tool.

One-line takeaway: tools aren't better because they're new, they're better because they fit you. I'm planning to use this for a week before I say anything definitive — you don't need to rush either.
