# Multimodal Inputs

> Use modality-specific user input parts with typed data/url sources in ag_ui.core

# Multimodal Inputs

`UserMessage.content` accepts either plain text or an ordered list of multimodal
parts.

```python theme={null}
from ag_ui.core import (
    UserMessage,
    TextInputContent,
    ImageInputContent,
    DocumentInputContent,
    InputContentUrlSource,
)

message = UserMessage(
    id="user-1",
    content=[
        TextInputContent(text="Summarize this PDF and screenshot"),
        ImageInputContent(
            source=InputContentUrlSource(
                value="https://example.com/screen.png",
                mime_type="image/png",
            )
        ),
        DocumentInputContent(
            source=InputContentUrlSource(
                value="https://example.com/report.pdf",
                mime_type="application/pdf",
            )
        ),
    ],
)
```

## Source Types

Use `source.type` to describe payload delivery:

* `data`: Inline base64 payload with required `mime_type`
* `url`: HTTP(S) or data URL, optional `mime_type`

## Common Use Cases

### Visual QA

```python theme={null}
from ag_ui.core import UserMessage, TextInputContent, ImageInputContent, InputContentUrlSource

message = UserMessage(
    id="q1",
    content=[
        TextInputContent(text="What issue do you see in this UI?"),
        ImageInputContent(
            source=InputContentUrlSource(
                value="https://example.com/ui.png",
                mime_type="image/png",
            ),
            metadata={"detail": "high"},
        ),
    ],
)
```

### Audio transcription

```python theme={null}
from ag_ui.core import UserMessage, TextInputContent, AudioInputContent, InputContentUrlSource

message = UserMessage(
    id="q2",
    content=[
        TextInputContent(text="Transcribe this recording."),
        AudioInputContent(
            source=InputContentUrlSource(
                value="https://example.com/meeting.wav",
                mime_type="audio/wav",
            )
        ),
    ],
)
```

### Deprecated binary model

`BinaryInputContent` is deprecated and emits a `DeprecationWarning`. It is kept
as a temporary compatibility path while migrating to modality-specific parts.
