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.
Creators · Tools Literacy · ~7 min read
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
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
