Brief

Three models (Composer 2, Claude Opus 4.6, GPT-5.4) were compared for building @threejs content in Cursor: Composer 2 was fastest and included tree animations, Opus 4.6 yielded the most game-like output, and GPT-5.4 produced the highest-detail UFO and terrain while taking the longest to finish.

Why it matters

Composer 2 completed the @threejs scenes fastest and added animated details (trees swaying) — finished “by a mile.”

Key details

  • Claude Opus 4.6 produced the most game-like result according to the author’s run in Cursor.
  • GPT-5.4 produced the most detailed UFO and terrain but had the longest render/creation time.
Source evidence

All the models are solid at @threejs in Cursor. It mostly comes down to speed and style preference.

Composer 2 finished first by a mile and even made the trees sway in the wind.

Opus 4.6 felt most game-like.

GPT-5.4 had the most detailed UFO and terrain but took the longest.
