Nitrode

Nitrode is a San Francisco AI research company building the evaluation, data, and post-training layer for game development. It started in Y Combinator's Winter 2025 batch as a Godot-based AI game engine that let anyone prototype a 3D game in a day, then pivoted toward frontier research: it runs GameEngineBench, a benchmark that scores how well AI models handle real game-engine coding tasks, and produces expert-labeled datasets and reinforcement-learning environments (including Unreal Engine 5) for AI labs and enterprises. Nitrode's bet is that game development will be handled by systems of specialized models working together, not one general-purpose model.
