LLM API Pricing Comparison

As large language models become mainstream, API call costs are a key consideration for developers and businesses. Different models have vastly different pricing — choosing the right model can save significant costs. This tool helps you quickly compare API pricing across major models to make the optimal choice.

Model Pricing Overview

Pricing strategies vary significantly: GPT-4o offers balanced pricing with strong capabilities; Claude 3.5 Sonnet provides excellent value; Gemini 2.0 Flash has the lowest pricing; DeepSeek V3 offers high-quality output at extremely low prices; open-source models like Llama can be self-hosted for free. Consider price, quality, speed, and privacy when choosing.

Tips to Reduce API Costs

What is an AI Token?
A token is the basic unit of text processing for LLMs. ~1 token = 0.75 English words or 0.5 Chinese characters. Input tokens are sent to the model; output tokens are the response. Most models price input and output separately, with output typically more expensive.
Is the pricing data up to date?
We update regularly, but API prices may change anytime. Verify on each model's official page before making decisions.
How do I estimate token counts?
English: ~1 word = 1.3 tokens. Chinese: ~1 character = 2 tokens. Code and special characters use more tokens.
Why are output tokens more expensive?
Generating output requires inference computation, which is 3-5x more intensive than processing input. Providers price output tokens higher to reflect this cost.
