Prompt
Flying Roadster jumping the Snake RiverThe post doesn’t quote the prompt wording.
The poster says Opus nailed the shape, while GPT got every detail right but made it look like a toy. Opus wins round 1.
@narushima_’s view (paraphrased)
GPT-6.1 Sol in Codex and Claude Opus 5.5 in Claude Code get the same prompt and reference photos, zero edits, to build a Roadster that flies over the Snake River and lands on its wheels.
Each side pairs a coding harness with its own model, so harness and model differences are mixed. More Claude Code vs OpenAI Codex. All harness comparisons.
