Ctrl+V 粘贴一张图片\n3. 发送消息\n4. 报 400 错误\n\n## 环境\n\n- deepcode-cli 版本：0.1.19\n- 模型：deepseek-v4-pro","author":{"url":"https://github.com/dengmik-commits","@type":"Person","name":"dengmik-commits"},"datePublished":"2026-05-13T06:51:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/50/deepcode-cli/issues/50"}
