About Qwen3.8 Flash

把分散的材料变成可用结论

Qwen3.8 Flash 是千问系列的多模态推理模型,可以阅读文字、理解图片和视频,再用文本给出分析结果。对于需要反复处理材料的团队,它适合承担文档摘要、图表解释、代码库问答、内容整理和业务助手等工作,让日常任务从收集信息推进到形成结论。

它的视觉能力很适合处理单靠文字难以描述的问题。上传一张报表截图,可以要求它比较不同渠道的走势、找出异常区间并解释图例;提供产品演示视频,可以让它梳理操作流程、总结用户卡点,并按片段列出需要复查的位置。做长视频分析时,先说明关心的事件和输出粒度,比笼统地要求“看一下视频”更容易得到有用结果。

在开发和自动化场景中,它也可以结合文档与代码分析功能依赖、解释错误,或通过函数调用请求外部系统提供信息。思考模式适合需要多步判断的任务;简单改写、分类和字段提取则应把要求写得简洁明确。需要把结果交给程序处理时,可以使用结构化输出,让字段名称和数据类型在请求中保持固定。

模型会输出文字分析,并不会因为看过视频就生成一段新视频。涉及报表数字或画面中的小字,建议提供清晰原图或原始数据;把观察到的内容和推测原因分开输出,也更方便人工复核。

Use cases and prompting

从一份图表开始

上传清晰的报表截图,说明统计口径、比较对象和需要做的决定。视频任务则说明关注的动作或事件,要求按片段整理发现。

提示词示例: “请分析这张渠道转化报表。先逐项列出能够读清的指标,再比较本周与上周的变化。把结论分成‘图中直接可见’和‘需要额外数据验证’,最后给出三项排查建议。看不清的数值不要补写。”

常见问题

  • 想分析整段视频,怎样减少遗漏?先列出事件清单,例如入口点击、报错、完成付款,再要求按发生顺序记录对应片段和依据。
  • 能把截图结果写入系统吗?需要应用配置可调用的函数;让模型先提取字段,再由工具执行写入,并检查工具返回结果。
  • 什么时候适合思考模式?跨材料比较、代码故障分析和多条件决策;简单字段抽取可直接给出固定格式。

Replace <YOUR_API_KEY> with the API key from your token settings.

Authentication

All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.

Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.
