Prompt

3D Lamborghini from code aloneThe post doesn’t quote the prompt wording.

Three coding agents build a 3D Lamborghini from the same prompt, all in code with no 3D files: Gemini 4 Argon in OpenCode, Claude Opus 5.5 in Claude Code and GPT-6 Astra in Codex.

Each side pairs a coding harness with its own model, so harness and model differences are mixed. More Claude Code vs OpenAI Codex. More Claude Code vs OpenCode. All harness comparisons.
