Recently, the AI field has witnessed a major breakthrough. Claude Opus 5 successfully generated a 3D game using just a single prompt and consuming 690 million tokens (costing $423). In the past, achieving such a result would have required a team several months and significant investment. Today, Opus 5 not only drastically reduces development costs but also demonstrates AI's immense potential in game development, signaling that the barrier to entry in the gaming industry is shifting from technical resources to imagination itself.
