What it means
GPT-5 is the conversation magnet this week, but Sora 2 is the model worth checking against your own workload — the gap on quality is narrower than the gap on attention. If you have a chat product running on the cheaper alternative, swap a small share of traffic to GPT-5 for a week and measure the lift on whatever your real metric is. Cost first, hype last.
