APIs de IA cobram por token (~750 palavras = 1.000 tokens). Com dólar a R$5,80, US$0,01/1K tokens = R$0,058. Para 1M tokens/dia: R$1.740/mês. Para empresas brasileiras, o custo pode ser deduzido como despesa operacional no Lucro Real.

Serviços digitais importados pagam ISS e potencialmente PIS/COFINS, adicionando 10-20% ao valor.

DeepSeek V3 and R1 disrupted the enterprise AI pricing landscape in early 2026. Multiple companies reported 60-80% API cost reductions by migrating appropriate workloads away from GPT-4o, while keeping premium models for high-stakes tasks only.
