Runway Gen-4 vs Hunyuan 3.0: Legacy Gemini Comparison
Legacy methodology: This article uses VibeDex's retired Gemini 3 Pro 200-prompt image benchmark. Its scores are historical and should not be compared directly with the Sonnet 4.6 public leaderboard. See the current Sonnet leaderboard
TL;DR
This is a legacy Gemini comparison. In the retired Gemini 3 Pro 200-prompt benchmark, Runway Gen-4 Image narrowly led Hunyuan Image 3.0, 4.064 to 4.037. Neither model appears in the current Sonnet 4.6 public image leaderboard, so this head-to-head should be treated as historical context only.

| 17 | Hunyuan Image 3.0 | 4.04 | $0.080 | Premium |
What the Legacy Result Means
Runway barely edged Hunyuan in the older run, but the practical conclusion was that both models were weak for their premium price point. That conclusion is historical; current public recommendations now use the Sonnet 4.6 leaderboard.
If you are choosing an image model today, use the current leaderboard and Atlas pages. This comparison is retained only for readers following older model coverage.
