Vision (image input) | truememory docs

You can send images to vision-capable models through chat completions by using the content parts format instead of a plain string for content. This follows the OpenAI Vision API format.

Each message’s content can be either:

A string (text-only, the default)
An array of content parts mixing text and images

Content part types

Type	Fields	Description
`text`	`text`	A text segment
`image_url`	`image_url.url`, `image_url.detail`	An image, either as a direct URL or base64 data URI

The detail parameter controls image resolution processing:

Value	Description
`auto`	Let the model decide (default)
`low`	Faster, lower resolution, fewer tokens
`high`	Higher resolution, more tokens

Sending an image URL

curl -X POST https://your-tie-host/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "model": "anthropic/claude-sonnet-4-5",
    "messages": [
      {
        "role": "user",
        "content": [
          { "type": "text", "text": "What is in this image?" },
          {
            "type": "image_url",
            "image_url": {
              "url": "https://example.com/photo.jpg",
              "detail": "auto"
            }
          }
        ]
      }
    ]
  }'

Sending a base64-encoded image

curl -X POST https://your-tie-host/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "model": "anthropic/claude-sonnet-4-5",
    "messages": [
      {
        "role": "user",
        "content": [
          { "type": "text", "text": "Describe this image." },
          {
            "type": "image_url",
            "image_url": {
              "url": "data:image/jpeg;base64,/9j/4AAQSkZJRg...",
              "detail": "low"
            }
          }
        ]
      }
    ]
  }'
