Title:

JSON Deserialization Failure When Including Images in Queries

Content:

Dear DeepSeek Team,

I encountered an error while using the DeepSeek model when attempting to include an image in my query. The system returned the following error message:

Failed to deserialize the JSON body into the target type: messages[3]: data did not match any variant of untagged enum ChatCompletionRequestContent at line 1 column 1673522

Steps to Reproduce:

Initiate a chat request containing both text and image data.

Submit the query to the DeepSeek API endpoint.

The error occurs consistently during JSON parsing of the input.

Expected Behavior:

The model should process multimodal inputs (text + image) without serialization errors.

Environment:

Model: DeepSeek

Input Format: Mixed (text + image)

Error Location: JSON deserialization at messages[3]
