 - 如果是en-zh互译、期待更高的速度，可以考虑`opus-mt-zh-en` / `opus-mt-en-zh`。（质量未详细评测，一些文章说比blib-200-600m更好，但是我看了些case感觉要差不少）
 
 **实时翻译选型建议**:
-- 在线 query 翻译如果只是 `en/zh` 互译，优先使用 `opus-mt-zh-en` 或 `opus-mt-en-zh`。
+- 在线 query 翻译如果只是 `en/zh` 互译，极致要求耗时使用 `opus-mt-zh-en / opus-mt-en-zh`，`nllb-200-distilled-600m`支持多语言，效果略好一点，但是耗时长很多（70-150ms之间）
 - 如果涉及其他语言，或对质量要求高于本地轻量模型，优先考虑 `deepl`。
-- `nllb-200-distilled-600m` 不建议作为在线 query 翻译默认方案；我们在 `Tesla T4` 上测到 `batch_size=1` 时，根据query长短，耗时大概在70-150ms之间。
 
 **Batch Size / 调用方式建议**:
 - 本接口支持 `text: string[]`；离线或批量索引翻译时，应尽量合并请求，让底层 backend 发挥批处理能力。
