DeepSeek-OCR 模型

DeepSeek-OCR 是一款先进的 OCR 模型，能够识别图片中的文字并将其转换为指定的文本格式。

请求示例

您可以通过向 https://api.modelverse.cn/v1/chat/completions 端点发送请求来使用 DeepSeek-OCR 模型。

说明： DeepSeek-OCR 支持 max_tokens 参数最大设置为 8192。当前该模型免费开放使用，无需付费。

注意： 该模型输入仅支持 base64 编码的图片（即 "data:image/..." 格式），不支持直接通过 image_url 远程图片地址。如果你的图片在远程地址，可以通过如下命令一键获取 base64 字符串：
curl -s https://umodelverse-inference.cn-wlcb.ufileos.com/ucloud-maxcot.jpg | base64 | tr -d '\n'
