LLM API Cost Comparison Tool
Compare monthly costs side-by-side between OpenAI GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro.
What is the LLM API Cost Comparison Tool?
The LLM API Cost Comparison Tool is a developer decision engine built to compare monthly API billing rates side-by-side for the leading frontier LLMs. It calculates costs based on your specific traffic levels and token counts for OpenAI's GPT-4o, Anthropic's Claude 3.5 Sonnet, and Google's Gemini 1.5 Pro, and highlights the most cost-efficient option for your scale.
How Does the LLM API Cost Comparison Tool Work?
1. Input Monthly Requests â Enter expected API calls per month.
2. Define Prompt Context â Specify your average input (prompt) tokens.
3. Define Response Length â Input average output (generated response) tokens.
4. Compare Bills â Review monthly payouts side-by-side to make the right software choices.
Formula & Calculation Method
Standard API Rates (per million tokens):
- GPT-4o: Input: $2.50 | Output: $10.00
- Claude 3.5 Sonnet: Input: $3.00 | Output: $15.00
- Gemini 1.5 Pro (<128k): Input: $1.25 | Output: $5.00
Equation:
- Bill = ((Input Tokens à Input Rate) + (Output Tokens à Output Rate)) / 1,000,000 à Monthly Requests
Example Calculation
Example: App handling 10,000 requests/mo, 5,000 input tokens, 1,000 output tokens.
- GPT-4o: ((5,000 Ã $2.50) + (1,000 Ã $10.00)) / 1M Ã 10,000 = $225.00
- Claude Sonnet: ((5,000 Ã $3.00) + (1,000 Ã $15.00)) / 1M Ã 10,000 = $300.00
- Gemini Pro: ((5,000 Ã $1.25) + (1,000 Ã $5.00)) / 1M Ã 10,000 = $112.50
- Winner: Gemini 1.5 Pro is the cheapest, saving you $187.50 over Claude!
