Create vector store file batch

$ openai vector-stores:file-batches create

POST/vector_stores/{vector_store_id}/file_batches

Create a vector store file batch.

ParametersExpand Collapse

--vector-store-id: string

The ID of the vector store for which to create a File Batch.

--attributes: optional map[string or number or boolean]

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.

--chunking-strategy: optional AutoFileChunkingStrategyParam { type } or StaticFileChunkingStrategyObjectParam { static, type }

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.

--file-id: optional array of string

A list of File IDs that the vector store should use. Useful for tools like file_search that can access files. If attributes or chunking_strategy are provided, they will be applied to all files in the batch. The maximum batch size is 2000 files. This endpoint is recommended for multi-file ingestion and helps reduce per-vector-store write request pressure. Mutually exclusive with files.

--file: optional array of object { file_id, attributes, chunking_strategy }

A list of objects that each include a file_id plus optional attributes or chunking_strategy. Use this when you need to override metadata for specific files. The global attributes or chunking_strategy will be ignored and must be specified for each file. The maximum batch size is 2000 files. This endpoint is recommended for multi-file ingestion and helps reduce per-vector-store write request pressure. Mutually exclusive with file_ids.
