Descriptions:
Nick Saraev spent $400 putting Claude Opus 5 through an extensive set of creative and technical tasks, presenting results through a 3D interactive gallery the model built entirely from scratch. The video argues Opus 5 is currently the best frontier large language model available, combining top-tier benchmark performance with pricing that undercuts Fable 5 (GPT-4.5-class) by roughly half.
Saraev walks through dozens of Opus 5-generated interactive demos: a Kerbal Space Program-style orbital mechanics simulator, cloth physics with real-time tearing, a fractal zoom generator with adjustable shaders, a cellular automaton sandbox, a predator-prey ecosystem with population dynamics, a quadcopter flight simulator, and a wrecking ball physics engine — all produced in single prompts with no external assets. He emphasizes that Opus 5 procedurally generates geometry and behavior rather than sourcing from the internet, which he views as a meaningful step forward in compositional reasoning.
On pricing, Saraev compares specific costs: Opus 5 produced a complex 3D airline-themed website for approximately 69 cents versus Fable 5’s 94 cents, with what he considers a superior visual result. His overall take positions Opus 5 as slightly more capable than Fable at roughly half the cost — a meaningful shift for developers and power users who build extensively with frontier APIs and need both quality and cost efficiency.
