LLM Gateway: Compare Options and Alternatives

Compare LLM gateway options and alternatives, from routing to receipts, and see how NextModel handles caching, failover, and auditability for production teams.

Caching · 2026-07-01

Semantic Caching for LLM APIs: A Practical Guide

Semantic caching reuses stored LLM responses for prompts with similar meaning, not just identical text. Learn how it works, when to use it, and how to tune it.

Provenance · 2026-07-01

AI Provenance: What It Is and Why It Matters

AI provenance means knowing which model produced an output and proving it later. See what a receipt records and how NextModel supports ai provenance today.
