-# VoyageAI Embeddings : Multimodal
-
-VoyageAI embeddings can also be used to embed both text and image data, only some of the models support image data and you can check the list
-under [https://docs.voyageai.com/docs/multimodal-embeddings](https://docs.voyageai.com/docs/multimodal-embeddings)
-
-Supported multimodal models:
-
-- `voyage-multimodal-3` - 1024 dimensions (text + images)
-- `voyage-multimodal-3.5` - Flexible dimensions (256, 512, 1024 default, 2048). Supports text, images, and video.
-
-### Video Support (voyage-multimodal-3.5)
-
-The `voyage-multimodal-3.5` model supports video input through:
-- Video URLs (`.mp4`, `.webm`, `.mov`, `.avi`, `.mkv`, `.m4v`, `.gif`)
-- Video file paths
-
-Constraints: Max 20MB video size.
-
-Supported parameters (to be passed in `create` method) are:
-
-| Parameter | Type | Default Value           | Description                               |
-|---|---|-------------------------|-------------------------------------------|
-| `name` | `str` | `"voyage-multimodal-3"` | The model ID of the VoyageAI model to use |
-| `output_dimension` | `int` | `None` | Output dimension for voyage-multimodal-3.5. Valid: 256, 512, 1024, 2048 |
-
-Usage Example:
-
-```python
-import base64
-import os
-from io import BytesIO
-
-import requests
-import lancedb
-from lancedb.pydantic import LanceModel, Vector
-from lancedb.embeddings import get_registry
-import pandas as pd
-
-os.environ['VOYAGE_API_KEY'] = 'YOUR_VOYAGE_API_KEY'
-
-db = lancedb.connect(".lancedb")
-func = get_registry().get("voyageai").create(name="voyage-multimodal-3")
-
-
-def image_to_base64(image_bytes: bytes):
-    buffered = BytesIO(image_bytes)
-    img_str = base64.b64encode(buffered.getvalue())
-    return img_str.decode("utf-8")
-
-
-class Images(LanceModel):
-    label: str
-    image_uri: str = func.SourceField()  # image uri as the source
-    image_bytes: str = func.SourceField()  # image bytes base64 encoded as the source
-    vector: Vector(func.ndims()) = func.VectorField()  # vector column
-    vec_from_bytes: Vector(func.ndims()) = func.VectorField()  # Another vector column
-
-
-if "images" in db.table_names():
-    db.drop_table("images")
-table = db.create_table("images", schema=Images)
-labels = ["cat", "cat", "dog", "dog", "horse", "horse"]
-uris = [
-    "http://farm1.staticflickr.com/53/167798175_7c7845bbbd_z.jpg",
-    "http://farm1.staticflickr.com/134/332220238_da527d8140_z.jpg",

-    "http://farm9.staticflickr.com/8216/8434969557_d37882c42d_z.jpg",
-    "http://farm6.staticflickr.com/5142/5835678453_4f3a4edb45_z.jpg",
-]
-# get each uri as bytes
-images_bytes = [image_to_base64(requests.get(uri).content) for uri in uris]
-table.add(
-    pd.DataFrame({"label": labels, "image_uri": uris, "image_bytes": images_bytes})
-)
-```
-Now we can search using text from both the default vector column and the custom vector column
-```python
-
-# text search
-actual = table.search("man's best friend", "vec_from_bytes").limit(1).to_pydantic(Images)[0]
-print(actual.label) # prints "dog"
-
-frombytes = (
-    table.search("man's best friend", vector_column_name="vec_from_bytes")
-    .limit(1)
-    .to_pydantic(Images)[0]
-)
-print(frombytes.label)
-
-```
-
-Because we're using a multi-modal embedding function, we can also search using images
-
-```python
-# image search
-query_image_uri = "http://farm1.staticflickr.com/200/467715466_ed4a31801f_z.jpg"
-image_bytes = requests.get(query_image_uri).content
-query_image = Image.open(BytesIO(image_bytes))
-actual = table.search(query_image, "vec_from_bytes").limit(1).to_pydantic(Images)[0]
-print(actual.label == "dog")
-
-# image search using a custom vector column
-other = (
-    table.search(query_image, vector_column_name="vec_from_bytes")
-    .limit(1)
-    .to_pydantic(Images)[0]
-)
-print(actual.label)
-

-        .get_instance()
-        .get("voyageai")
-        .create(name="voyage-3")
-
-    class TextModel(LanceModel):
-        text: str = voyageai.SourceField()
-        vector: Vector(voyageai.ndims()) =  voyageai.VectorField()
-
-    data = [ { "text": "hello world" },
-            { "text": "goodbye world" }]
-

-## Metadata Operations
-
-### Creating a Namespace
-
-Namespaces organize tables hierarchically. Create a namespace before creating tables within it:
-
-```java
-import org.lance.namespace.model.CreateNamespaceRequest;
-import org.lance.namespace.model.CreateNamespaceResponse;
-
-// Create a child namespace
-CreateNamespaceRequest request = new CreateNamespaceRequest();
-request.setId(Arrays.asList("my_namespace"));
-
-CreateNamespaceResponse response = namespaceClient.createNamespace(request);
-```
-
-You can also create nested namespaces:
-
-```java
-// Create a nested namespace: parent/child
-CreateNamespaceRequest request = new CreateNamespaceRequest();
-request.setId(Arrays.asList("parent_namespace", "child_namespace"));
-
-CreateNamespaceResponse response = namespaceClient.createNamespace(request);
-```
-
-### Describing a Namespace
-
-```java
-import org.lance.namespace.model.DescribeNamespaceRequest;
-import org.lance.namespace.model.DescribeNamespaceResponse;
-
-DescribeNamespaceRequest request = new DescribeNamespaceRequest();
-request.setId(Arrays.asList("my_namespace"));
-
-DescribeNamespaceResponse response = namespaceClient.describeNamespace(request);
-System.out.println("Namespace properties: " + response.getProperties());
-```
-
-### Listing Namespaces
-
-```java
-import org.lance.namespace.model.ListNamespacesRequest;
-import org.lance.namespace.model.ListNamespacesResponse;
-
-// List all namespaces at root level
-ListNamespacesRequest request = new ListNamespacesRequest();
-request.setId(Arrays.asList());  // Empty for root
-
-ListNamespacesResponse response = namespaceClient.listNamespaces(request);
-for (String ns : response.getNamespaces()) {
-    System.out.println("Namespace: " + ns);
-}
-
-// List child namespaces under a parent
-ListNamespacesRequest childRequest = new ListNamespacesRequest();
-childRequest.setId(Arrays.asList("parent_namespace"));
-
-ListNamespacesResponse childResponse = namespaceClient.listNamespaces(childRequest);
-```
-
-### Listing Tables
-
-```java
-import org.lance.namespace.model.ListTablesRequest;
-import org.lance.namespace.model.ListTablesResponse;
-
-// List tables in a namespace
-ListTablesRequest request = new ListTablesRequest();
-request.setId(Arrays.asList("my_namespace"));
-
-ListTablesResponse response = namespaceClient.listTables(request);
-for (String table : response.getTables()) {
-    System.out.println("Table: " + table);
-}
-```
-
-### Dropping a Namespace
-
-```java
-import org.lance.namespace.model.DropNamespaceRequest;
-import org.lance.namespace.model.DropNamespaceResponse;
-
-DropNamespaceRequest request = new DropNamespaceRequest();
-request.setId(Arrays.asList("my_namespace"));
-
-DropNamespaceResponse response = namespaceClient.dropNamespace(request);
-```
-
-### Describing a Table
-
-```java
-import org.lance.namespace.model.DescribeTableRequest;
-import org.lance.namespace.model.DescribeTableResponse;
-
-DescribeTableRequest request = new DescribeTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-DescribeTableResponse response = namespaceClient.describeTable(request);
-System.out.println("Table version: " + response.getVersion());
-System.out.println("Schema fields: " + response.getSchema().getFields());
-```
-
-### Dropping a Table
-
-```java
-import org.lance.namespace.model.DropTableRequest;
-import org.lance.namespace.model.DropTableResponse;
-
-DropTableRequest request = new DropTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-DropTableResponse response = namespaceClient.dropTable(request);
-```
-
-## Writing Data
-
-### Creating a Table
-
-Tables are created within a namespace by providing data in Apache Arrow IPC format:
-
-```java
-import org.lance.namespace.LanceNamespace;
-import org.lance.namespace.model.CreateTableRequest;
-import org.lance.namespace.model.CreateTableResponse;
-import org.apache.arrow.memory.BufferAllocator;
-import org.apache.arrow.memory.RootAllocator;
-import org.apache.arrow.vector.IntVector;
-import org.apache.arrow.vector.VarCharVector;
-import org.apache.arrow.vector.VectorSchemaRoot;
-import org.apache.arrow.vector.complex.FixedSizeListVector;
-import org.apache.arrow.vector.Float4Vector;
-import org.apache.arrow.vector.ipc.ArrowStreamWriter;
-import org.apache.arrow.vector.types.FloatingPointPrecision;
-import org.apache.arrow.vector.types.pojo.ArrowType;
-import org.apache.arrow.vector.types.pojo.Field;
-import org.apache.arrow.vector.types.pojo.FieldType;
-import org.apache.arrow.vector.types.pojo.Schema;
-
-import java.io.ByteArrayOutputStream;
-import java.nio.channels.Channels;
-import java.util.Arrays;
-
-// Create schema with id, name, and embedding fields
-Schema schema = new Schema(Arrays.asList(
-    new Field("id", FieldType.nullable(new ArrowType.Int(32, true)), null),
-    new Field("name", FieldType.nullable(new ArrowType.Utf8()), null),
-    new Field("embedding",
-        FieldType.nullable(new ArrowType.FixedSizeList(128)),
-        Arrays.asList(new Field("item",
-            FieldType.nullable(new ArrowType.FloatingPoint(FloatingPointPrecision.SINGLE)),
-            null)))
-));
-
-try (BufferAllocator allocator = new RootAllocator();
-     VectorSchemaRoot root = VectorSchemaRoot.create(schema, allocator)) {
-
-    // Populate data
-    root.setRowCount(3);
-    IntVector idVector = (IntVector) root.getVector("id");
-    VarCharVector nameVector = (VarCharVector) root.getVector("name");
-    FixedSizeListVector embeddingVector = (FixedSizeListVector) root.getVector("embedding");
-    Float4Vector embeddingData = (Float4Vector) embeddingVector.getDataVector();
-
-    for (int i = 0; i < 3; i++) {
-        idVector.setSafe(i, i + 1);
-        nameVector.setSafe(i, ("item_" + i).getBytes());
-        embeddingVector.setNotNull(i);
-        for (int j = 0; j < 128; j++) {
-            embeddingData.setSafe(i * 128 + j, (float) i);
-        }
-    }
-    idVector.setValueCount(3);
-    nameVector.setValueCount(3);
-    embeddingData.setValueCount(3 * 128);
-    embeddingVector.setValueCount(3);
-
-    // Serialize to Arrow IPC format
-    ByteArrayOutputStream out = new ByteArrayOutputStream();
-    try (ArrowStreamWriter writer = new ArrowStreamWriter(root, null, Channels.newChannel(out))) {
-        writer.start();
-        writer.writeBatch();
-        writer.end();
-    }
-    byte[] tableData = out.toByteArray();
-
-    // Create table in a namespace
-    CreateTableRequest request = new CreateTableRequest();
-    request.setId(Arrays.asList("my_namespace", "my_table"));
-    CreateTableResponse response = namespaceClient.createTable(request, tableData);
-}
-```
-
-### Insert
-
-```java
-import org.lance.namespace.model.InsertIntoTableRequest;
-import org.lance.namespace.model.InsertIntoTableResponse;
-
-// Prepare data in Arrow IPC format (similar to create table example)
-byte[] insertData = prepareArrowData();
-
-InsertIntoTableRequest request = new InsertIntoTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-request.setMode(InsertIntoTableRequest.ModeEnum.APPEND);
-
-InsertIntoTableResponse response = namespaceClient.insertIntoTable(request, insertData);
-System.out.println("New version: " + response.getVersion());
-```
-
-### Update
-
-Update rows matching a predicate condition:
-
-```java
-import org.lance.namespace.model.UpdateTableRequest;
-import org.lance.namespace.model.UpdateTableResponse;
-
-UpdateTableRequest request = new UpdateTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Predicate to select rows to update
-request.setPredicate("id = 1");
-
-// Set new values using SQL expressions as [column_name, expression] pairs
-request.setUpdates(Arrays.asList(
-    Arrays.asList("name", "'updated_name'")
-));
-
-UpdateTableResponse response = namespaceClient.updateTable(request);
-System.out.println("Updated rows: " + response.getUpdatedRows());
-```
-
-### Delete
-
-Delete rows matching a predicate condition:
-
-```java
-import org.lance.namespace.model.DeleteFromTableRequest;
-import org.lance.namespace.model.DeleteFromTableResponse;
-
-DeleteFromTableRequest request = new DeleteFromTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Predicate to select rows to delete
-request.setPredicate("id > 100");
-
-DeleteFromTableResponse response = namespaceClient.deleteFromTable(request);
-System.out.println("New version: " + response.getVersion());
-```
-
-### Merge Insert (Upsert)
-
-Merge insert allows you to update existing rows and insert new rows in a single operation based on a key column:
-
-```java
-import org.lance.namespace.model.MergeInsertIntoTableRequest;
-import org.lance.namespace.model.MergeInsertIntoTableResponse;
-
-// Prepare data with rows to update (id=2,3) and new rows (id=4)
-byte[] mergeData = prepareArrowData();  // Contains rows with id=2,3,4
-
-MergeInsertIntoTableRequest request = new MergeInsertIntoTableRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-// Match on the "id" column
-request.setOn("id");
-
-// Update all columns when a matching row is found
-request.setWhenMatchedUpdateAll(true);
-
-// Insert new rows when no match is found
-request.setWhenNotMatchedInsertAll(true);
-
-MergeInsertIntoTableResponse response = namespaceClient.mergeInsertIntoTable(request, mergeData);
-
-System.out.println("Updated rows: " + response.getNumUpdatedRows());
-System.out.println("Inserted rows: " + response.getNumInsertedRows());
-```
-
-## Querying Data
-
-### Counting Rows
-
-```java
-import org.lance.namespace.model.CountTableRowsRequest;
-
-CountTableRowsRequest request = new CountTableRowsRequest();
-request.setId(Arrays.asList("my_namespace", "my_table"));
-
-Long rowCount = namespaceClient.countTableRows(request);
-System.out.println("Row count: " + rowCount);
-```
-
-### Vector Search
-
-```java
-import org.lance.namespace.model.QueryTableRequest;
-import org.lance.namespace.model.QueryTableRequestVector;
-
-QueryTableRequest query = new QueryTableRequest();
-query.setId(Arrays.asList("my_namespace", "my_table"));
-query.setK(10);  // Return top 10 results
-
-// Set the query vector
-List<Float> queryVector = new ArrayList<>();
-for (int i = 0; i < 128; i++) {
-    queryVector.add(1.0f);
-}
-QueryTableRequestVector vector = new QueryTableRequestVector();
-vector.setSingleVector(queryVector);
-query.setVector(vector);
-
-// Specify columns to return
-query.setColumns(Arrays.asList("id", "name", "embedding"));
-
-// Execute query - returns Arrow IPC format
-byte[] result = namespaceClient.queryTable(query);
-```
-
-### Full Text Search
-
-```java
-import org.lance.namespace.model.QueryTableRequest;
-import org.lance.namespace.model.QueryTableRequestFullTextQuery;
-import org.lance.namespace.model.StringFtsQuery;
-
-QueryTableRequest query = new QueryTableRequest();
-query.setId(Arrays.asList("my_namespace", "my_table"));
-query.setK(10);
-
-// Set full text search query
-StringFtsQuery stringQuery = new StringFtsQuery();
-stringQuery.setQuery("search terms");
-stringQuery.setColumns(Arrays.asList("text_column"));
-
-QueryTableRequestFullTextQuery fts = new QueryTableRequestFullTextQuery();
-fts.setStringQuery(stringQuery);
-query.setFullTextQuery(fts);
-
-// Specify columns to return
-query.setColumns(Arrays.asList("id", "text_column"));
-
-byte[] result = namespaceClient.queryTable(query);
-```
-
-### Query with Filter
-
-```java
-QueryTableRequest query = new QueryTableRequest();
-query.setId(Arrays.asList("my_namespace", "my_table"));
-query.setK(10);
-query.setFilter("id > 50");
-query.setColumns(Arrays.asList("id", "name"));
-
-byte[] result = namespaceClient.queryTable(query);
-```
-
-### Query with Prefilter
-
-```java
-QueryTableRequest query = new QueryTableRequest();
-query.setId(Arrays.asList("my_namespace", "my_table"));
-query.setK(5);
-query.setPrefilter(true);  // Apply filter before vector search
-query.setFilter("category = 'electronics'");
-
-// Set query vector
-QueryTableRequestVector vector = new QueryTableRequestVector();
-vector.setSingleVector(queryVector);
-query.setVector(vector);
-
-byte[] result = namespaceClient.queryTable(query);
-```
-
-### Reading Query Results
