AI Gateway vs. Direct Provider APIs: When to Insert the Hop

AI Gateway vs. Direct Provider APIs: When to Insert the Hop

Vercel AI Gateway, OpenRouter, LiteLLM, and Portkey — what gateways add and what they cost.

Section 1

The premise

An AI gateway buys you provider portability, retries, and cost dashboards — at the cost of an extra hop and a new vendor relationship.

What AI does well here

Failover across providers when one is down
Cache identical prompts to cut cost
Centralize per-team budgets and rate limits
Provide consistent logging across providers

Insert-the-hop checklist

Use a gateway when: multi-provider failover matters, you have >5 teams sharing budgets, or you need cross-provider analytics. Otherwise, call providers directly and revisit at scale.

Check-in 1. Got it so far?

What AI cannot do

Hide provider-specific quirks (tool-call schema, vision support)
Add zero latency — there is always a hop cost
Replace the need to read provider release notes

Gateways become single points of failure

If the gateway is down, every AI feature is down. Build a direct-provider fallback path even if you ship through the gateway.

Key terms in this lesson

OpenRouter
LiteLLM
Portkey
routing

Check-in 2. Got it so far?

Evaluate systematically

Before adopting any AI tool: check the data policy, benchmark on your actual use cases, and plan an exit strategy. Vendor lock-in with AI tools can be painful.
