Opus 5.5 vs. GPT-6 Astra Showdown

👉 Single Brain - Revenue agents to scale faster using our unified intelligence layer. https://www.singlebrain.com I put Claude Opus 5.5 and GPT-6 Astra through seven work tasks with the same prompts at medium settings. We compare YouTube packaging, ad teardowns, lead journeys, stalled deals, case studies and proposals, video editing, and AEO. Watch the actual outputs, follow the running score, and see where each model was useful. These are my results from these tasks. I still use and pay for both models.
