Steins;Gate Drive: Semantic Safety Arbitration over Structured Futures for Latency-Decoupled LLM Planning
Researchers have developed a new planning architecture called SteinsGateDrive for LLM-driven autonomous vehicles, addressing the issue of high inference latency. This system decouples planning from runtime by generating multiple potential future driving scenarios, allowing the LLM to select a forecast that remains valid within safety constraints. In testing, this approach significantly reduced effective lag for GPT-5.4 mini, maintaining a no-collision safety boundary. AI
