+### Pinecone
+
+When using Pinecone as the vector store, the following environment variables are used to control its behavior. Make sure to set these variables in your `.env` file or deployment environment.
+
+#### `PINECONE_API_KEY`
+
+- Type: `str`
+- Default: `None`
+- Description: Sets the API key used to authenticate with the Pinecone service.
+
+#### `PINECONE_ENVIRONMENT`
+
+- Type: `str`
+- Default: `None`
+- Description: Specifies the Pinecone environment to connect to (e.g., `us-west1-gcp`, `gcp-starter`, etc.).
+
+#### `PINECONE_INDEX_NAME`
+
+- Type: `str`
+- Default: `open-webui-index`
+- Description: Defines the name of the Pinecone index that will be used to store and query vector embeddings.
+
+#### `PINECONE_DIMENSION`
+
+- Type: `int`
+- Default: `1536`
+- Description: The dimensionality of the vector embeddings. Must match the dimension expected by the index (commonly 768, 1024, 1536, or 3072 based on model used).
+
+#### `PINECONE_METRIC`
+
+- Type: `str`
+- Default: `cosine`
+- Options: `cosine`, `dotproduct`, `euclidean`
+- Description: Specifies the similarity metric to use for vector comparisons within the Pinecone index.
