NagaAI uses pay-as-you-go billing. You add credits to your account, send requests, and each request deducts cost based on the model and the amount of input and output processed. Different models have different prices, so the final cost depends on both the model you choose and how much content the request processes.

​
Billing at a glance

  • There is no monthly plan requirement.
  • You are billed per request.
  • Pricing varies by model.
  • Paid model access requires a positive balance.
  • A first top-up of at least $5 unlocks access to paid models.

​
What Are Tokens?

Tokens are the units models use to process input and generate output. Depending on the API, tokens can represent:
  • words or parts of words
  • punctuation and symbols
  • image content
  • audio content
As a rough rule of thumb, 1 token is about 4 characters or about 0.75 words in English.

​
Input vs Output Tokens

Most model pricing separates input tokens from output tokens.
Token TypeDescriptionCost
Input TokensContent you send to the model (prompts, images, audio)Lower cost
Output TokensContent generated by the model (responses, images, audio, etc.)Higher cost
Output tokens usually cost more because generation is more computationally expensive than processing input.

​
Example cost calculation

Here is a simple example using sample token prices. Check the live model catalog for current pricing. 
Hello! Can you help me?
If the model returns: 
Hello! I'd be happy to help you. What do you need assistance with today?
  • Input cost: 14 x $0.0000015 = $0.000021
  • Output cost: 21 x $0.0000075 = $0.0001575
  • Total cost: $0.0001785
