Create vector store file

client.vectorStores.files.create(stringvectorStoreID, FileCreateParams { file_id, attributes, chunking_strategy } body, RequestOptionsoptions?): VectorStoreFile { id, created_at, last_error, 6 more }
POST/vector_stores/{vector_store_id}/files

Create a vector store file by attaching a File to a vector store.

ParametersExpand Collapse
vectorStoreID: string
body: FileCreateParams { file_id, attributes, chunking_strategy }
file_id: string

A File ID that the vector store should use. Useful for tools like file_search that can access files. For multi-file ingestion, we recommend file_batches to minimize per-vector-store write requests.

attributes?: Record<string, string | number | boolean> | null

Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard. Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters, booleans, or numbers.

One of the following:
string
number
boolean
chunking_strategy?: FileChunkingStrategyParam

The chunking strategy used to chunk the file(s). If not set, will use the auto strategy. Only applicable if file_ids is non-empty.

One of the following:
AutoFileChunkingStrategyParam { type }

The default strategy. This strategy currently uses a max_chunk_size_tokens of 800 and chunk_overlap_tokens of 400.

type: "auto"

Always auto.

StaticFileChunkingStrategyObjectParam { static, type }

Customize your own chunking strategy by setting chunk size and chunk overlap.

static: StaticFileChunkingStrategy { chunk_overlap_tokens, max_chunk_size_tokens }
chunk_overlap_tokens: number

The number of tokens that overlap between chunks. The default value is 400.

Note that the overlap must not exceed half of max_chunk_size_tokens.

max_chunk_size_tokens: number

The maximum number of tokens in each chunk. The default value is 800. The minimum value is 100 and the maximum value is 4096.

minimum100
maximum4096
type: "static"

Always static.

ReturnsExpand Collapse
VectorStoreFile { id, created_at, last_error, 6 more }

A list of files attached to a vector store.

id: string

The identifier, which can be referenced in API endpoints.

created_at: number

The Unix timestamp (in seconds) for when the vector store file was created.

last_error: LastError | null

The last error associated with this vector store file. Will be null if there are no errors.

code: "server_error" | "unsupported_file" | "invalid_file"

One of server_error, unsupported_file, or invalid_file.

One of the following:
"server_error"
"unsupported_file"
"invalid_file"
message: string

A human-readable description of the error.

object: "vector_store.file"

The object type, which is always vector_store.file.

status: "in_progress" | "completed" | "cancelled" | "failed"

The status of the vector store file, which can be either in_progress, completed, cancelled, or failed. The status completed indicates that the vector store file is ready for use.

One of the following:
"in_progress"
"completed"
"cancelled"
"failed"
usage_bytes: number

The total vector store usage in bytes. Note that this may be different from the original file size.

vector_store_id: string

The ID of the vector store that the File is attached to.

attributes?: Record<string, string | number | boolean> | null

Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard. Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters, booleans, or numbers.

One of the following:
string
number
boolean
chunking_strategy?: FileChunkingStrategy

The strategy used to chunk the file.

One of the following:
StaticFileChunkingStrategyObject { static, type }
static: StaticFileChunkingStrategy { chunk_overlap_tokens, max_chunk_size_tokens }
chunk_overlap_tokens: number

The number of tokens that overlap between chunks. The default value is 400.

Note that the overlap must not exceed half of max_chunk_size_tokens.

max_chunk_size_tokens: number

The maximum number of tokens in each chunk. The default value is 800. The minimum value is 100 and the maximum value is 4096.

minimum100
maximum4096
type: "static"

Always static.

OtherFileChunkingStrategyObject { type }

This is returned when the chunking strategy is unknown. Typically, this is because the file was indexed before the chunking_strategy concept was introduced in the API.

type: "other"

Always other.
