O que é Calculadora de Tokens de IA?

A powerful developer tool designed to help you work more efficiently. AI Token Calculator provides accurate results instantly with a clean, intuitive interface. Perfect for developers, engineers, and IT professionals.

Fórmula

Cost = (InputTokens ÷ 1000) × InputPrice + (OutputTokens ÷ 1000) × OutputPrice

Pricing per 1K tokens:

- GPT-4o: $0.0025 input / $0.01 output

- GPT-4o Mini: $0.00015 input / $0.0006 output

- Claude 3 Opus: $0.015 input / $0.075 output

- Claude 3 Sonnet: $0.003 input / $0.015 output

- Claude 3 Haiku: $0.00025 input / $0.00125 output

- Gemini 1.5 Pro: $0.00125 input / $0.005 output

- Gemini 1.5 Flash: $0.000075 input / $0.0003 output

Como calcular

Enter your input in the field above.
Configure any available options to customize the output.
View the results instantly with real-time updates.
Copy or export your results for use in your projects.
Compare os custos entre diferentes modelos para o mesmo uso de tokens.

Exemplo

A developer sends 2,000 input tokens to GPT-4o and receives 500 output tokens. The cost is (2000/1000 × $0.0025) + (500/1000 × $0.01) = $0.005 + $0.005 = $0.01 total. For 10,000 daily API calls, this would cost about $100 per day or $3,000 per month.

Perguntas Frequentes

What is an IA token?

A token is the basic unit of texto that IA modelos process. Roughly 1 token = 0.75 words in English. tokens include words, subwords, punctuation, and spaces.

How are IA API custos calculated?

Costs are calculated as (input tokens / 1000) × input price + (output tokens / 1000) × output price. Each model has its own per-1K-token pricing.

Which modelo is cheapest?

Gemini 1.5 Flash and Claude 3 Haiku are the most affordable. GPT-4o Mini offers great value. Claude 3 Opus is the most expensive.

How many tokens does a typical request uso?

A simple Q&A might uso 100-500 entrada tokens. Document analysis can uso 10K-100K+ tokens. Code generation typically usos 500-2000 tokens.
