GPT-5 Chat · Strengths & Key Advantages

  • Janela de contexto de 128K com limite máximo de saída de 16K tokens (SWE-bench Verified 70% · GPQA Diamond 79%)
  • Taxa de transferência rápida de 140 tokens/segundo com latência inicial (TTFT) de 1050 ms
  • Economia de API competitiva (acesso gratuito de pesos abertos) com suporte a cache de prompts e saídas JSON estruturadas
Considerations & Trade-offs
  • Modelo proprietário em nuvem; não permite download dos pesos para execução local offline
  • Em derivações científicas extremas, modelos pesados dedicados exclusivamente ao raciocínio oferecem maior profundidade
