GPT-6.1 Sol · Strengths & Key Advantages
- Janela de contexto de 1M com limite máximo de saída de 128K tokens (SWE-bench Verified 82.3% · GPQA Diamond 80.8%)
- Taxa de transferência rápida de 120 tokens/segundo com latência inicial (TTFT) de 1120 ms
- Economia de API competitiva ($2/$10 por 1M de tokens) 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
- Para alto volume de requisições, recomenda-se ativar o cache de prompts e a Batch API para reduzir custos
Kimi K3 · Strengths & Key Advantages
- Janela de contexto de 1.0M com limite máximo de saída de 131K tokens (SWE-bench Verified 74.5% · GPQA Diamond 79%)
- Taxa de transferência rápida de 58 tokens/segundo com latência inicial (TTFT) de 720 ms
- Pesos abertos (2.8T total (MoE)) para auto-hospedagem local ou em nuvem privada via vLLM, SGLang ou Ollama
Considerations & Trade-offs
- Requer servidores GPU com memória VRAM adequada para execução local em precisão total
- Em derivações científicas extremas, modelos pesados dedicados exclusivamente ao raciocínio oferecem maior profundidade
