Description

GPT-5.5 dropped last week and the internet hasn't shut up about it. Switch now. Drop Claude. Move everything to OpenAI. So Gael actually did it. He swiped completely to Codex and GPT-5.5 for a week, ran the same business prompts on both models, and compared the real outputs side by side. The verdict isn't what you'd expect from the hype cycle. In this episode we break down: → Why GPT-5.5 is more thorough but Claude still wins for marketers → The two-engineers analogy that explains where each model shines → How GPT-5.5 gives you 3x more usage on the $100 plan → Real head-to-head test: same brief, very different ad creative → Why you don't have to "marry" one LLM (and how to use both) → Inside the new Codex desktop app and where it beats Claude → Why people are moving back to Opus 4.6 from 4.7 → Meta finally releases an MCP and CLI for ads → DeepSeek's new V Fall model and why it matters Don't get distracted. Pick the right tool for the work in front of you. 🔗 AI Accelerator: https://www.authorityhacker.com/ai-accelerator (monthly plans are available until 💻 Learn Claude Code: https://www.authorityhacker.com/resources/learn-claude-code/ ⏱️ Timestamps: 00:00 - GPT-5.5 dropped: should you switch? 01:55 - The two engineers analogy (American vs German) 05:31 - Why Codex gives 3x more usage 09:24 - Test 1: Social posts head-to-head 14:50 - Test 2: Meta ad creatives compared 22:46 - Which model to use for which task 30:03 - Don't panic switch 33:43 - Inside the new Codex desktop app 42:17 - Opus 4.6 vs 4.7: why people are moving back 46:36 - Meta finally launches ads MCP and CLI 54:11 - DeepSeek's super-cheap V Fall model
