Aya Expanse 8B · Strengths & Key Advantages
- Janela de contexto de 8K com limite máximo de saída de 4K tokens (SWE-bench Verified 24% · GPQA Diamond 40%)
- Taxa de transferência rápida de 135 tokens/segundo com latência inicial (TTFT) de 300 ms
- Pesos abertos (8B) 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
GPT-6 Astra · Strengths & Key Advantages
- Janela de contexto de 272K com limite máximo de saída de 128K tokens (SWE-bench Verified 82.4% · GPQA Diamond 80.9%)
- Taxa de transferência rápida de 100 tokens/segundo com latência inicial (TTFT) de 950 ms
- Economia de API competitiva ($10/$50 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
