Our pick
For most workloads, choose GPT-5.
- 50% cheaper input price, which compounds at scale
- 3.1× the context window — better for long documents and agents
- 26% faster throughput — matters for streaming UX and voice agents
Best across-the-board quality but the most expensive token rate in the table; pick GPT-5 when reasoning depth or function-calling reliability outranks per-million-token spend.
Choose Grok 3 instead if: 尚未记录这对模型的具体取舍。两者质量差距可能很小，最终决定因素更多是工作负载契合度、集成成本与团队熟悉度。

为何选择？通过智能路由同时使用两者
第二阶段 · 带故障转移链的网关Set GPT-5 as primary, Grok 3 as fallback. One key, one bill, automatic failover when GPT-5 errors.
第二阶段预览 · 网关尚未上线该接口目前不存在。网关计划在第二阶段上线——下面只是规划中的接口形态预览，不是可用的 API。上线时会通过 newsletter 通知订阅者。
