Five frontier models, five different superpowers. After running them side by side on real campaigns for six months, here's which one I open for which marketing job — and the brand-safety landmine that makes Grok-Imagine unusable for most brands.

A production 3-model content pipeline where each AI does only what it is actually best at: ChatGPT drafts, Claude reviews, GPT-Image generates visuals. The actual hand-off prompts, the JSON contract between stages, the $0.41 / 18-minute cost and timing comparison vs single-model, and the model-identity-confusion failure mode that cost me a published post.
A production n8n workflow that pulls decaying posts from GSC (Google Search Console, 谷歌站长工具), drafts a refresh brief, has ChatGPT write the update, validates the new draft, and ships it to the CMS — all in one loop. The full node map, the three prompts, the four validation gates, and the three failure modes that have actually cost me a post.
You can build a real 4-channel MMM (Marketing Mix Model, 营销组合模型) in a Google Sheet in one afternoon — no Python, no data engineer, no $40K vendor. I walked a DTC client through it last quarter. The build took 3 hours, the adstock decay curves are written by ChatGPT, and the sensitivity test exposed a $14K/month waste nobody had spotted.
I cut my own LinkedIn posting schedule to once a week and filled the other four slots with substantive comments on other people's posts — profile views up 47% in a month, two DMs into booked calls. The full Perplexity-research / ChatGPT-draft / human-edit loop, the contrarian-first prompt, the Friday tracking ritual, and the rules that keep it from going spammy.
Generate 100 subject lines with ChatGPT, filter them down to 5 with a 4-criterion rubric, then A/B/n test the finalists. The exact prompt, the 5 that made it through, and the test result — including the variant I would never have written on my own that beat my favorite by 19%.
