# v0.1.0
Published on: 2025-01-24T17:47:47Z
We are excited to announce a stable API release of Llama Stack, which enables developers to build RAG applications and Agents using tools and safety shields, monitor and those agents with telemetry, and evaluate the agent with scoring functions.
## Context
GenAI application developers need more than just an LLM - they need to integrate tools, connect with their data sources, establish guardrails, and ground the LLM responses effectively. Currently, developers must piece together various tools and APIs, complicating the development lifecycle and increasing costs. The result is that developers are spending more time on these integrations rather than focusing on the application logic itself. The bespoke coupling of components also makes it challenging to adopt state-of-the-art solutions in the rapidly evolving GenAI space. This is particularly difficult for open models like Llama, as best practices are not widely established in the open.
Llama Stack was created to provide developers with a comprehensive and coherent interface that simplifies AI application development and codifies best practices across the Llama ecosystem. Since our launch in September 2024, we have seen a huge uptick in interest in Llama Stack APIs by both AI developers and from partners building AI services with Llama models. Partners like Nvidia, Fireworks, and Ollama have collaborated with us to develop implementations across various APIs, including inference, memory, and safety.
With Llama Stack, you can easily build a RAG agent which can also search the web, do complex math, and custom tool calling. You can use telemetry to inspect those traces, and convert telemetry into evals datasets. And with Llama Stacks plugin architecture and prepackage distributions, you choose to run your agent anywhere - in the cloud with our partners, deploy your own environment using virtualenv, conda, or Docker, operate locally with Ollama, or even run on mobile devices with our SDKs. Llama Stack offers unprecedented flexibility while also simplifying the developer experience.
## Release
After iterating on the APIs for the last 3 months, today were launching a stable release (V1) of the Llama Stack APIs and the corresponding llama-stack server and client packages(v0.1.0). We now have automated tests for providers. These tests make sure that all provider implementations are verified. Developers can now easily and reliably select distributions or providers based on their specific requirements.
There are example standalone apps in llama-stack-apps.
## Key Features of this release
- **Unified API Layer**
- Inference: Run LLM models
- RAG: Store and retrieve knowledge for RAG
- Agents: Build multi-step agentic workflows
- Tools: Register tools that can be called by the agent
- Safety: Apply content filtering and safety policies
- Evaluation: Test model and agent quality
- Telemetry: Collect and analyze usage data and complex agentic traces
- Post Training ( Coming Soon ): Fine tune models for specific use cases
- **Rich Provider Ecosystem**
- Local Development: Meta's Reference, Ollama
- Cloud: Fireworks, Together, Nvidia, AWS Bedrock, Groq, Cerebras
- On-premises: Nvidia NIM, vLLM, TGI, Dell-TGI
- On-device: iOS and Android support
- **Built for Production**
- Pre-packaged distributions for common deployment scenarios
- Backwards compatibility across model versions
- Comprehensive evaluation capabilities
- Full observability and monitoring
- **Multiple developer interfaces**
- CLI: Command line interface
- Python SDK
- Swift iOS SDK
- Kotlin Android SDK
- **Sample llama stack applications**
- Python

* Comments should provide meaningful insights into the code. Avoid filler comments that simply
describe the next step, as they create unnecessary clutter, same goes for docstrings.
* Prefer comments to clarify surprising behavior and/or relationships between parts of the code
rather than explain what the next line of code does.
* Catching exceptions, prefer using a specific exception type rather than a broad catch-all like
`Exception`.

#### Using Precomputed Embeddings
If you decide to precompute embeddings for your documents, you can insert them directly into the vector database by
including the embedding vectors in the chunk data. This is useful if you have a separate embedding service or if you
want to customize the ingestion process.
```python
chunks_with_embeddings = [
{
"content": "First chunk of text",
"mime_type": "text/plain",
"embedding": [0.1, 0.2, 0.3, ...], # Your precomputed embedding vector
"metadata": {"document_id": "doc1", "section": "introduction"},
},
{
"content": "Second chunk of text",
"mime_type": "text/plain",
"embedding": [0.2, 0.3, 0.4, ...], # Your precomputed embedding vector
"metadata": {"document_id": "doc1", "section": "methodology"},
},
]
client.vector_io.insert(vector_db_id=vector_db_id, chunks=chunks_with_embeddings)
```
When providing precomputed embeddings, ensure the embedding dimension matches the embedding_dimension specified when
registering the vector database.
### Retrieval

### Using the RAG Tool
A better way to ingest documents is to use the RAG Tool. This tool allows you to ingest documents from URLs, files, etc.

The Code Interpreter allows execution of Python code within a controlled environment.
```python
# Register Code Interpreter tool group
client.toolgroups.register(

Features:
- Secure execution environment using `bwrap` sandboxing
- Matplotlib support for generating plots
- Disabled dangerous system operations
- Configurable execution timeouts
> ⚠️ Important: The code interpreter tool can operate in a controlled environment locally or on Podman containers. To ensure proper functionality in containerized environments:
> - The container requires privileged access (e.g., --privileged).
> - Users without sufficient permissions may encounter permission errors. (`bwrap: Can't mount devpts on /newroot/dev/pts: Permission denied`)
> - 🔒 Security Warning: Privileged mode grants elevated access and bypasses security restrictions. Use only in local, isolated, or controlled environments.

- Begin by reviewing the [core concepts](../concepts/index.md) of Llama Stack and choose the API your provider belongs to (Inference, Safety, VectorIO, etc.)
- Determine the provider type ({repopath}`Remote::llama_stack/providers/remote` or {repopath}`Inline::llama_stack/providers/inline`). Remote providers make requests to external services, while inline providers execute implementation locally.
- Add your provider to the appropriate {repopath}`Registry::llama_stack/providers/registry/`. Specify pip dependencies necessary.
- Update any distribution {repopath}`Templates::llama_stack/templates/` `build.yaml` and `run.yaml` files if they should include your provider by default. Run {repopath}`./scripts/distro_codegen.py` if necessary. Note that `distro_codegen.py` will fail if the new provider causes any distribution template to attempt to import provider-specific dependencies. This usually means the distribution's `get_distribution_template()` code path should only import any necessary Config or model alias definitions from each provider and not the provider's actual implementation.

:::{tab-item} Building with External Providers
Llama Stack supports external providers that live outside of the main codebase. This allows you to create and maintain your own providers independently or use community-provided providers.
To build a distribution with external providers, you need to:
1. Configure the `external_providers_dir` in your build configuration file:
```yaml
# Example my-external-stack.yaml with external providers
version: '2'
distribution_spec:
description: Custom distro for CI tests
providers:
inference:
- remote::custom_ollama
# Add more providers as needed
image_type: container
image_name: ci-test
# Path to external provider implementations
external_providers_dir: ~/.llama/providers.d
```
Here's an example for a custom Ollama provider:
```yaml
adapter:
adapter_type: custom_ollama
pip_packages:
- ollama
- aiohttp
- llama-stack-provider-ollama # This is the provider package
config_class: llama_stack_ollama_provider.config.OllamaImplConfig
module: llama_stack_ollama_provider
api_dependencies: []
optional_api_dependencies: []
```
The `pip_packages` section lists the Python packages required by the provider, as well as the
provider package itself. The package must be available on PyPI or can be provided from a local
directory or a git repository (git must be installed on the build environment).
2. Build your distribution using the config file:
```
llama stack build --config my-external-stack.yaml
```
For more information on external providers, including directory structure, provider types, and implementation requirements, see the [External Providers documentation](../providers/external.md).

### Listing Distributions
Using the list command, you can view all existing Llama Stack distributions, including stacks built from templates, from scratch, or using custom configuration files.
```
llama stack list -h
usage: llama stack list [-h]
list the build stacks
options:
-h, --help show this help message and exit
```
Example Usage
```
llama stack list
```
### Removing a Distribution
Use the remove command to delete a distribution you've previously built.
```
llama stack rm -h
usage: llama stack rm [-h] [--all] [name]
Remove the build stack
positional arguments:
name Name of the stack to delete (default: None)
options:
-h, --help show this help message and exit
--all, -a Delete all stacks (use with caution) (default: False)
```
Example
```
llama stack rm llamastack-test
```
To keep your environment organized and avoid clutter, consider using `llama stack list` to review old or unused distributions and `llama stack rm <name>` to delete them when theyre no longer needed.

What's with the `provider_model_id` field? This is an identifier for the model inside the provider's model catalog. Contrast it with `model_id` which is the identifier for the same model for Llama Stack's purposes. For example, you may want to name "llama3.2:vision-11b" as "image_captioning_model" when you use it in your Stack interactions. When omitted, the server will set `provider_model_id` to be the same as `model_id`.
## Server Configuration
The `server` section configures the HTTP server that serves the Llama Stack APIs:
```yaml
server:
port: 8321 # Port to listen on (default: 8321)
tls_certfile: "/path/to/cert.pem" # Optional: Path to TLS certificate for HTTPS
tls_keyfile: "/path/to/key.pem" # Optional: Path to TLS key for HTTPS
```
### Authentication Configuration
The `auth` section configures authentication for the server. When configured, all API requests must include a valid Bearer token in the Authorization header:
```
Authorization: Bearer <token>
```
The server supports multiple authentication providers:
#### OAuth 2.0/OpenID Connect Provider with Kubernetes
The Kubernetes cluster must be configured to use a service account for authentication.
```bash
kubectl create namespace llama-stack
kubectl create serviceaccount llama-stack-auth -n llama-stack
kubectl create rolebinding llama-stack-auth-rolebinding --clusterrole=admin --serviceaccount=llama-stack:llama-stack-auth -n llama-stack
kubectl create token llama-stack-auth -n llama-stack > llama-stack-auth-token
```
Make sure the `kube-apiserver` runs with `--anonymous-auth=true` to allow unauthenticated requests
and that the correct RoleBinding is created to allow the service account to access the necessary
resources. If that is not the case, you can create a RoleBinding for the service account to access
the necessary resources:
```yaml
# allow-anonymous-openid.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: allow-anonymous-openid
rules:
- nonResourceURLs: ["/openid/v1/jwks"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: allow-anonymous-openid
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: allow-anonymous-openid
subjects:
- kind: User
name: system:anonymous
apiGroup: rbac.authorization.k8s.io
```
And then apply the configuration:
```bash
kubectl apply -f allow-anonymous-openid.yaml
```
Validates tokens against the Kubernetes API server through the OIDC provider:
```yaml
server:
auth:
provider_type: "oauth2_token"
config:
jwks:
uri: "https://kubernetes.default.svc"
key_recheck_period: 3600
tls_cafile: "/path/to/ca.crt"
issuer: "https://kubernetes.default.svc"
audience: "https://kubernetes.default.svc"
```
To find your cluster's audience, run:
```bash
kubectl create token default --duration=1h | cut -d. -f2 | base64 -d | jq .aud
```
For the issuer, you can use the OIDC provider's URL:
```bash
kubectl get --raw /.well-known/openid-configuration| jq .issuer
```
For the tls_cafile, you can use the CA certificate of the OIDC provider:
```bash
kubectl config view --minify -o jsonpath='{.clusters[0].cluster.certificate-authority}'
```
The provider extracts user information from the JWT token:
- Username from the `sub` claim becomes a role
- Kubernetes groups become teams
You can easily validate a request by running:
```bash
curl -s -L -H "Authorization: Bearer $(cat llama-stack-auth-token)" http://127.0.0.1:8321/v1/providers
```
#### Custom Provider
Validates tokens against a custom authentication endpoint:
```yaml
server:
auth:
provider_type: "custom"
config:
endpoint: "https://auth.example.com/validate" # URL of the auth endpoint
```
The custom endpoint receives a POST request with:
```json
{
"api_key": "<token>",
"request": {
"path": "/api/v1/endpoint",
"headers": {
"content-type": "application/json",
"user-agent": "curl/7.64.1"
},
"params": {
"key": ["value"]
}
}
}
```
And must respond with:
```json
{
"access_attributes": {
"roles": ["admin", "user"],
"teams": ["ml-team", "nlp-team"],
"projects": ["llama-3", "project-x"],
"namespaces": ["research"]
},
"message": "Authentication successful"
}
```
If no access attributes are returned, the token is used as a namespace.
### Quota Configuration
The `quota` section allows you to enable server-side request throttling for both
authenticated and anonymous clients. This is useful for preventing abuse, enforcing
fairness across tenants, and controlling infrastructure costs without requiring
client-side rate limiting or external proxies.
Quotas are disabled by default. When enabled, each client is tracked using either:
* Their authenticated `client_id` (derived from the Bearer token), or
* Their IP address (fallback for anonymous requests)
Quota state is stored in a SQLite-backed key-value store, and rate limits are applied
within a configurable time window (currently only `day` is supported).
#### Example
```yaml
server:
quota:
kvstore:
type: sqlite
db_path: ./quotas.db
anonymous_max_requests: 100
authenticated_max_requests: 1000
period: day
```
#### Configuration Options
| Field | Description |
| ---------------------------- | -------------------------------------------------------------------------- |
| `kvstore` | Required. Backend storage config for tracking request counts. |
| `kvstore.type` | Must be `"sqlite"` for now. Other backends may be supported in the future. |
| `kvstore.db_path` | File path to the SQLite database. |
| `anonymous_max_requests` | Max requests per period for unauthenticated clients. |
| `authenticated_max_requests` | Max requests per period for authenticated clients. |
| `period` | Time window for quota enforcement. Only `"day"` is supported. |
> Note: if `authenticated_max_requests` is set but no authentication provider is
configured, the server will fall back to applying `anonymous_max_requests` to all
clients.
#### Example with Authentication Enabled
```yaml
server:
port: 8321
auth:
provider_type: custom
config:
endpoint: https://auth.example.com/validate
quota:
kvstore:
type: sqlite
db_path: ./quotas.db
anonymous_max_requests: 100
authenticated_max_requests: 1000
period: day
```
If a client exceeds their limit, the server responds with:
```http
HTTP/1.1 429 Too Many Requests
Content-Type: application/json
{
"error": {
"message": "Quota exceeded"
}
}
```
## Extending to handle Safety
Configuring Safety can be a little involved so it is instructive to go through an example.

# Meta Reference Quantized Distribution
```{toctree}
:maxdepth: 2
:hidden:
self
```
The `llamastack/distribution-meta-reference-quantized-gpu` distribution consists of the following provider configurations:
| API | Provider(s) |
|-----|-------------|
| agents | `inline::meta-reference` |
| datasetio | `remote::huggingface`, `inline::localfs` |
| eval | `inline::meta-reference` |
| inference | `inline::meta-reference-quantized` |
| safety | `inline::llama-guard` |

| vector_io | `inline::faiss`, `remote::chromadb`, `remote::pgvector` |
The only difference vs. the `meta-reference-gpu` distribution is that it has support for more efficient inference -- with fp8, int4 quantization, etc.
Note that you need access to nvidia GPUs to run this distribution. This distribution is not compatible with CPU-only machines or machines with AMD GPUs.
### Environment Variables
The following environment variables can be configured:
- `LLAMA_STACK_PORT`: Port for the Llama Stack distribution server (default: `8321`)
- `INFERENCE_MODEL`: Inference model loaded into the Meta Reference server (default: `meta-llama/Llama-3.2-3B-Instruct`)
- `INFERENCE_CHECKPOINT_DIR`: Directory containing the Meta Reference model checkpoint (default: `null`)
## Prerequisite: Downloading Models
Please use `llama model list --downloaded` to check that you have llama model checkpoints downloaded in `~/.llama` before proceeding. See [installation guide](https://llama-stack.readthedocs.io/en/latest/references/llama_cli_reference/download_models.html) here to download the models. Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.
```

## Running the Distribution
You can do this via Conda (build code) or Docker which has a pre-built image.
### Via Docker
This method allows you to get started quickly without having to build the distribution code.
```bash
LLAMA_STACK_PORT=8321
docker run \
-it \
--pull always \
-p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
-v ~/.llama:/root/.llama \
llamastack/distribution-meta-reference-quantized-gpu \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct
```
If you are using Llama Stack Safety / Shield APIs, use:
```bash
docker run \
-it \
--pull always \
-p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
-v ~/.llama:/root/.llama \
llamastack/distribution-meta-reference-quantized-gpu \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
--env SAFETY_MODEL=meta-llama/Llama-Guard-3-1B
```
### Via Conda
Make sure you have done `uv pip install llama-stack` and have the Llama Stack CLI available.
```bash
llama stack build --template meta-reference-quantized-gpu --image-type conda
llama stack run distributions/meta-reference-quantized-gpu/run.yaml \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct
```
If you are using Llama Stack Safety / Shield APIs, use:
```bash
llama stack run distributions/meta-reference-quantized-gpu/run-with-safety.yaml \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
--env SAFETY_MODEL=meta-llama/Llama-Guard-3-1B

## Prerequisites
### NVIDIA API Keys
### Prerequisite: API Keys
Make sure you have access to a NVIDIA API Key. You can get one by visiting [https://build.nvidia.com/](https://build.nvidia.com/). Use this key for the `NVIDIA_API_KEY` environment variable.
Make sure you have access to a NVIDIA API Key. You can get one by visiting [https://build.nvidia.com/](https://build.nvidia.com/).
### Deploy NeMo Microservices Platform
The NVIDIA NeMo microservices platform supports end-to-end microservice deployment of a complete AI flywheel on your Kubernetes cluster through the NeMo Microservices Helm Chart. Please reference the [NVIDIA NeMo Microservices documentation](https://docs.nvidia.com/nemo/microservices/latest/about/index.html) for platform prerequisites and instructions to install and deploy the platform.
## Supported Services
Each Llama Stack API corresponds to a specific NeMo microservice. The core microservices (Customizer, Evaluator, Guardrails) are exposed by the same endpoint. The platform components (Data Store) are each exposed by separate endpoints.
### Inference: NVIDIA NIM
NVIDIA NIM is used for running inference with registered models. There are two ways to access NVIDIA NIMs:
1. Hosted (default): Preview APIs hosted at https://integrate.api.nvidia.com (Requires an API key)
2. Self-hosted: NVIDIA NIMs that run on your own infrastructure.
The deployed platform includes the NIM Proxy microservice, which is the service that provides to access your NIMs (for example, to run inference on a model). Set the `NVIDIA_BASE_URL` environment variable to use your NVIDIA NIM Proxy deployment.
### Datasetio API: NeMo Data Store
The NeMo Data Store microservice serves as the default file storage solution for the NeMo microservices platform. It exposts APIs compatible with the Hugging Face Hub client (`HfApi`), so you can use the client to interact with Data Store. The `NVIDIA_DATASETS_URL` environment variable should point to your NeMo Data Store endpoint.
See the [NVIDIA Datasetio docs](/llama_stack/providers/remote/datasetio/nvidia/README.md) for supported features and example usage.
### Eval API: NeMo Evaluator
The NeMo Evaluator microservice supports evaluation of LLMs. Launching an Evaluation job with NeMo Evaluator requires an Evaluation Config (an object that contains metadata needed by the job). A Llama Stack Benchmark maps to an Evaluation Config, so registering a Benchmark creates an Evaluation Config in NeMo Evaluator. The `NVIDIA_EVALUATOR_URL` environment variable should point to your NeMo Microservices endpoint.
See the [NVIDIA Eval docs](/llama_stack/providers/remote/eval/nvidia/README.md) for supported features and example usage.
### Post-Training API: NeMo Customizer
The NeMo Customizer microservice supports fine-tuning models. You can reference [this list of supported models](/llama_stack/providers/remote/post_training/nvidia/models.py) that can be fine-tuned using Llama Stack. The `NVIDIA_CUSTOMIZER_URL` environment variable should point to your NeMo Microservices endpoint.
See the [NVIDIA Post-Training docs](/llama_stack/providers/remote/post_training/nvidia/README.md) for supported features and example usage.
### Safety API: NeMo Guardrails
The NeMo Guardrails microservice sits between your application and the LLM, and adds checks and content moderation to a model. The `GUARDRAILS_SERVICE_URL` environment variable should point to your NeMo Microservices endpoint.
See the NVIDIA Safety docs for supported features and example usage.
## Deploying models
In order to use a registered model with the Llama Stack APIs, ensure the corresponding NIM is deployed to your environment. For example, you can use the NIM Proxy microservice to deploy `meta/llama-3.2-1b-instruct`.
Note: For improved inference speeds, we need to use NIM with `fast_outlines` guided decoding system (specified in the request body). This is the default if you deployed the platform with the NeMo Microservices Helm Chart.
```sh
# URL to NeMo NIM Proxy service
export NEMO_URL="http://nemo.test"
curl --location "$NEMO_URL/v1/deployment/model-deployments" \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"name": "llama-3.2-1b-instruct",
"namespace": "meta",
"config": {
"model": "meta/llama-3.2-1b-instruct",
"nim_deployment": {
"image_name": "nvcr.io/nim/meta/llama-3.2-1b-instruct",
"image_tag": "1.8.3",
"pvc_size": "25Gi",
"gpu": 1,
"additional_envs": {
"NIM_GUIDED_DECODING_BACKEND": "fast_outlines"
}
}
}
}'
```
This NIM deployment should take approximately 10 minutes to go live. [See the docs](https://docs.nvidia.com/nemo/microservices/latest/get-started/tutorials/deploy-nims.html) for more information on how to deploy a NIM and verify it's available for inference.
You can also remove a deployed NIM to free up GPU resources, if needed.
```sh
export NEMO_URL="http://nemo.test"
curl -X DELETE "$NEMO_URL/v1/deployment/model-deployments/meta/llama-3.1-8b-instruct"
```

### Setting up vLLM server on Intel GPU
Refer to [vLLM Documentation for XPU](https://docs.vllm.ai/en/v0.8.2/getting_started/installation/gpu.html?device=xpu) to get a vLLM endpoint. In addition to vLLM side setup which guides towards installing vLLM from sources orself-building vLLM Docker container, Intel provides prebuilt vLLM container to use on systems with Intel GPUs supported by PyTorch XPU backend:
- [intel/vllm](https://hub.docker.com/r/intel/vllm)
Here is a sample script to start a vLLM server locally via Docker using Intel provided container:
```bash
export INFERENCE_PORT=8000
export INFERENCE_MODEL=meta-llama/Llama-3.2-1B-Instruct
export ZE_AFFINITY_MASK=0
docker run \
--pull always \

If you are using Llama Stack Safety / Shield APIs, then you will need to also run another instance of a vLLM with a corresponding safety model like `meta-llama/Llama-Guard-3-1B` using a script like:
```bash
export SAFETY_PORT=8081

# Milvus
[Milvus](https://milvus.io/) is an inline and remote vector database provider for Llama Stack. It
allows you to store and query vectors directly within a Milvus database.
That means you're not limited to storing vectors in memory or in a separate service.
## Features
- Easy to use
- Fully integrated with Llama Stack
## Usage
To use Milvus in your Llama Stack project, follow these steps:
1. Install the necessary dependencies.
2. Configure your Llama Stack project to use Milvus.
3. Start storing and querying vectors.
## Installation
You can install Milvus using pymilvus:
```bash
pip install pymilvus
```
## Configuration
In Llama Stack, Milvus can be configured in two ways:
- **Inline (Local) Configuration** - Uses Milvus-Lite for local storage
- **Remote Configuration** - Connects to a remote Milvus server
### Inline (Local) Configuration
The simplest method is local configuration, which requires setting `db_path`, a path for locally storing Milvus-Lite files:
```yaml
vector_io:
- provider_id: milvus
provider_type: inline::milvus
config:
db_path: ~/.llama/distributions/together/milvus_store.db
```
### Remote Configuration
Remote configuration is suitable for larger data storage requirements:
#### Standard Remote Connection
```yaml
vector_io:
- provider_id: milvus
provider_type: remote::milvus
config:
uri: "http://<host>:<port>"
token: "<user>:<password>"
```
#### TLS-Enabled Remote Connection (One-way TLS)
For connections to Milvus instances with one-way TLS enabled:
```yaml
vector_io:
- provider_id: milvus
provider_type: remote::milvus
config:
uri: "https://<host>:<port>"
token: "<user>:<password>"
secure: True
server_pem_path: "/path/to/server.pem"
```
#### Mutual TLS (mTLS) Remote Connection
For connections to Milvus instances with mutual TLS (mTLS) enabled:
```yaml
vector_io:
- provider_id: milvus
provider_type: remote::milvus
config:
uri: "https://<host>:<port>"
token: "<user>:<password>"
secure: True
ca_pem_path: "/path/to/ca.pem"
client_pem_path: "/path/to/client.pem"
client_key_path: "/path/to/client.key"
```
#### Key Parameters for TLS Configuration
- **`secure`**: Enables TLS encryption when set to `true`. Defaults to `false`.
- **`server_pem_path`**: Path to the **server certificate** for verifying the servers identity (used in one-way TLS).
- **`ca_pem_path`**: Path to the **Certificate Authority (CA) certificate** for validating the server certificate (required in mTLS).
- **`client_pem_path`**: Path to the **client certificate** file (required for mTLS).
- **`client_key_path`**: Path to the **client private key** file (required for mTLS).
## Documentation
See the [Milvus documentation](https://milvus.io/docs/install-overview.md) for more details about Milvus in general.
For more details on TLS configuration, refer to the [TLS setup guide](https://milvus.io/docs/tls.md).

When using the RAGTool interface, you can specify the desired search behavior via the `mode` parameter in
`RAGQueryConfig`. For example:
```python
from llama_stack.apis.tool_runtime.rag import RAGQueryConfig
query_config = RAGQueryConfig(max_chunks=6, mode="vector")
results = client.tool_runtime.rag_tool.query(
