Top 5 AI Gateways for Multi-Model Routing
AI gateways have become critical infrastructure for teams building with multiple LLMs. This article compares five leading options: Bifrost, the open-source AI gateway by Maxim AI, alongside Cloudflare AI Gateway, LiteLLM, Vercel AI Gateway, and Kong AI Gateway, across platform overview, key features, and best use cases.
TL;DR
Gemini API Pricing in 2026 and How to Cut What You Pay
TL;DR
* Gemini 3.8 Flash, 3.7 Flash, and 3.6 Flash all bill at $0.75 per million input tokens and $3.75 per million output tokens on the standard paid tier, and all three rates double on January 1, 2027.
* Gemini output pricing includes thinking tokens, so
LLM Budget Management: Virtual Keys and Hierarchical Spend Controls
TL;DR
* Virtual keys are gateway-issued credentials that carry their own budget, rate limits, and model access, so an AI budget can be attached to each team, project, or user instead of a shared provider key.
* Bifrost enforces budgets hierarchically at the customer, team, virtual key, and provider-config
Top AI Gateways to Reduce LLM Cost and Latency
Cost and latency pull in opposite directions at the gateway. This guide maps where each comes from, then compares five AI gateways on caching, routing, budget granularity, and published overhead.
How to Cut LLM API and Token Costs in 2026
TL;DR
* LLM token cost is driven by six sources: model selection, output length, repeated queries, tool-definition bloat, retries, and missing enforcement. Each one can be fixed once at the gateway layer.
* Output tokens are priced three to eight times higher than input tokens, and per-token pricing varies
