Hi Vercel team,

I’m currently using Vercel AI Gateway on the pay-as-you-go plan, and I’d like to better understand the production rate limits.

Could you clarify the following?

• What are the current limits for pay-as-you-go accounts regarding:

  • Requests per minute (RPM)
  • Tokens per minute (TPM)

• Are these limits applied globally at the account level, or separately per provider/model (OpenAI, Anthropic, Google, etc.)?

• Do rate limits automatically increase over time based on account usage or spending, similar to OpenAI usage tiers?

• If an application requires consistently high throughput (for example, serving hundreds of concurrent users), what is the best way to avoid or minimize rate limit issues in production?

Thanks!
