AI Gateway

TL;DR: LLM API costs compound fast at scale. An AI gateway adds a control layer between your app and providers to enforce caching, fallbacks, and budgets. Bifrost (by Maxim AI) leads on cost ops with semantic caching, virtual key budgets, 12+ providers, and native observability. Cloudflare AI Gateway is

Fintech companies are deploying LLM-powered applications across fraud detection, credit decisioning, customer support automation, and regulatory compliance workflows. As these systems move from prototype to production, the infrastructure connecting applications to LLM providers becomes a critical scaling bottleneck. Provider outages, unpredictable API costs, fragmented authentication schemes, and compliance requirements around

AI governance has shifted from a best practice to a regulatory imperative. With the EU AI Act imposing fines of up to 35 million euros or 7% of global turnover for non-compliance, and high-risk system rules taking full effect in August 2026, enterprises can no longer treat governance as an

As LLM-powered applications scale from prototype to production, token costs can spiral quickly. A single unoptimized prompt chain can multiply expenses by 10x, and without real-time visibility into usage patterns, teams often discover budget overruns only after the damage is done. Effective cost and usage monitoring has become a non-negotiable

OpenRouter has established itself as a popular multi-model API gateway, providing developers with a single endpoint to access 500+ LLMs from 60+ providers. For prototyping and early-stage experimentation, its simplicity is hard to beat. However, as AI workloads mature and teams move toward production-grade deployments, OpenRouter's architecture reveals

TL;DR AI gateways have become critical infrastructure for teams building with multiple LLMs. This article covers five leading options: Bifrost, Cloudflare AI Gateway, LiteLLM, Vercel AI Gateway, and Kong AI Gateway, comparing them across platform overview, key features, and best use cases. Why Multi-Model Routing Matters No single LLM
