Token Pricing

OpenAI Token Pricing & Consumption Guide

Understand how OpenAI token pricing works for translation. Pay only for what you use with transparent, usage-based pricing across all GPT models.

What are Tokens?

Tokens are pieces of text that AI models process. In English, 1 token ≈ 4 characters or ≈ 0.75 words. A typical page of text contains about 500-800 tokens.

Input vs Output

Input tokens are the source text you provide. Output tokens are the translated result. Both are counted separately with different pricing tiers.

Cost Efficiency

Choose the model that fits your needs. GPT-4o-mini offers the best value for standard translations, while GPT-4o excels at complex content.

Pricing Examples

Small Document (1,000 words)

~1,333 input tokens, ~1,333 output tokens

$0.001 with GPT-4.1 mini
