Portkey's BYOK model means your keys, your rotation, your audit — and governance that starts at Enterprise.
A gateway that manages keys for you has to own the billing too. The only questions: who holds the keys, and what they gate behind a plan line.
Helicone's async SDK means no vendor in your request path — and by construction it can't enforce anything.
A guardrail that refuses a call has to be in the path. The only questions: who, and what they gate behind a plan line.
Un #LLMGateway es como un API Gateway, pero para modelos de #IA: una capa única entre tus apps y OpenAI, Anthropic o Gemini.
Enrutamiento, cuotas, tracing, guardrails y fallbacks en un solo sitio. Y con agentes, el punto ideal para capturar trazas y evaluar.
Already using Kong? Keep the existing API edge and evaluate whether the LLM layer needs specialized routing, guardrails and budget controls.
Read the nRouter comparison:
A router recommends. A gateway executes.
See how NotDiamond’s model-selection layer differs from nRouter’s managed request path for provider access, budgets, guardrails and logs.
Your AI stack doesn’t need separate infrastructure for every provider.
nRouter brings model access, smart routing, fallbacks, guardrails, observability, and budget controls into one OpenAI-compatible gateway.

Specialist observability or a unified LLM gateway?
Langfuse focuses on observability, prompts, and evaluations. nRouter combines observability with routing and governance.
An LLM experiment isn’t deterministic if the same user keeps switching variants.
Hash a stable identifier to preserve assignment across calls and produce cleaner comparisons.

Don’t route based on headline model prices.
Route by task, test on your own workload, and compare measured cost per successful output against proven quality.
