I put GPT-5 to the test and it’s UNREAL

GPT-5 is here — and it’s the most powerful AI model OpenAI has ever released. In this video, I put GPT-5 vs GPT-4 (and even Grok-4) through real-world AI n8n workflows to see just how much it has improved. First, I test GPT-5 for AI video generation, creating a personalised sales video using my AI clone and comparing it directly with previous GPT versions. Then, I put GPT-5 customer support capabilities to the test — acting as a sneaker shop support agent — and measure it against GPT-4 and Grok-4 for speed, accuracy, and personalisation.
