I Battle-Tested GPT-5.5 In My Business

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.
