## Key Takeaways

- Setup: **GPT-5.5 with extended thinking** (paid plan) vs **Claude Opus 4.7 with adaptive thinking on** (paid plan with desktop app) — best-of-best comparison for each platform.
- Tasks covered: app building, writing, landing page design, business strategy, data analysis, teaching, video planning, and more across 10 rounds.
- Google Gemini scores both independently 1–10 per prompt, adding a third-party perspective rather than the creator's subjective judgment.
- Notable style difference: Claude Opus tends to produce consistent, same-style designs (same font, same layout) unless explicitly directed otherwise. ChatGPT GPT-5.5 tends to produce more varied, colorful output.
- Both platforms have dedicated coding environments — Claude Code (desktop app required) and ChatGPT Codex — but this test uses the base chat interface only for direct comparison.
- For the coding-assistant comparison specifically, see the [Codex setup guide](https://openclawdatabase.com/chatgpt/setup/) and the [Claude Code setup guide](https://openclawdatabase.com/claude-cowork/setup/).
