How to try it
You pick the model through the AI SDK, Chat Completions, Responses or Anthropic Messages. According to the post, the command npx vercel@latest ai-gateway setup prepares a key and configuration for agents such as Claude Code or Codex, then you choose the model with /model. Vercel says the gateway passes provider prices through with no markup and charges no platform fee on requests.
How to read this
The post gives no prices or test results, and ‘fewer errors’ is a vendor claim, not an independent measurement. Before you switch, try the model on a few tasks of your own. I write more about models in this class in the hub on frontier models.
