Gemini 4 Argon vs GPT-6 vs Fable 5.1 | Ultimate Comparison

In this deep dive, I break down the massive capabilities and benchmarks of Google Gemini 4, putting them head-to-head across 10 intense generative coding and 3D simulation tests against OpenAI’s GPT-6 Astra and Anthropic’s Claude Fable 5.1. From building interactive Three.js mechanical models and voxel micro-worlds to generating fully playable 3D games, vector graphics, and cinematic physics simulations directly from prompts, we test which model truly leads the next era of AI software engineering. I also examine the leaked official benchmark scoreboard, breaking down coding benchmarks (DeepSWE
