A large language model (LLM) gateway is a centralized interface unifying access to multiple models via a single API. It allows businesses to manage neural networks from one place, ensuring unified security and cost control. These gateways boost resilience through automatic failover and request caching to optimize budgets.
As companies actively move to full-scale AI infrastructure, LLM gateways have become mission-critical. This transition drives massive growth: the LLM gateway market reached $2.76B in 2026 and is projected to hit $7.21B by 2030.
