Rate limits mainly matter for free models. Paid models do not use the same fixed request caps, though all traffic is still protected against abuse.

​
How Rate Limits Work

NagaAI has two access categories: free models and paid models.

​
Free Models

All :free models share a combined rate limit:
Limit TypeValue
Requests per Minute (RPM)10
Requests per Day (RPD)100
Finding Free Models You can view all available free models on our models page — just look for the :free tag.
These limits apply whether or not your account has a positive balance. Free models are a good fit for:
  • Testing and experimentation
  • Getting familiar with the API
Paid models do not have the same fixed RPM and RPD caps. In practice, your usage is mainly constrained by:
  • Your account balance: you need enough credits to process requests
  • Abuse protection: platform security systems still protect against automated abuse and denial-of-service traffic

​
Getting Access to Paid Models

To unlock access to paid models, you need to:
  1. Top up your balance with a minimum of $5 through the Billing Dashboard
  2. Maintain a positive balance — As long as you have credits, you can use paid models
Your account is typically upgraded right after the first top-up, which unlocks paid-model access.
