These are the source-of-truth configuration files used to generate the Stainless client SDKs via Stainless.
- `openapi.yml`: this is the OpenAPI specification for the Llama Stack API.
- `openapi.stainless.yml`: this is the Stainless _configuration_ which instructs Stainless how to generate the client SDKs.
- `config.yml`: this is the Stainless _configuration_ which instructs Stainless how to generate the client SDKs.
A small side note: notice the `.yml` suffixes since Stainless uses that suffix typically for its configuration files.
These files go hand-in-hand. As of now, only the `openapi.yml` file is automatically generated using the `run_openapi_generator.sh` script.

### Step 3: Configure Llama Stack
### Step 3: Install Kubernetes Operator
Update your run configuration:
```yaml
providers:
inference:
- provider_id: vllm
provider_type: remote::vllm
config:
url: http://vllm-server.default.svc.cluster.local:8000/v1

# Or install a specific version (e.g., v0.4.0)
# kubectl apply -f https://raw.githubusercontent.com/llamastack/llama-stack-k8s-operator/v0.4.0/release/operator.yaml
```
### Step 4: Deploy Llama Stack Server
Verify the operator is running:
```bash
kubectl get pods -n llama-stack-operator-system
```
For more information about the operator, see the [llama-stack-k8s-operator repository](https://github.com/llamastack/llama-stack-k8s-operator).
### Step 4: Deploy Llama Stack Server using Operator
Create a `LlamaStackDistribution` custom resource to deploy the Llama Stack server. The operator will automatically create the necessary Deployment, Service, and other resources.
You can optionally override the default `run.yaml` using `spec.server.userConfig` with a ConfigMap (see [userConfig spec](https://github.com/llamastack/llama-stack-k8s-operator/blob/main/docs/api-overview.md#userconfigspec)).

```
**Configuration Options:**
- `replicas`: Number of Llama Stack server instances to run
- `server.distribution.name`: The distribution to use (e.g., `starter` for the starter distribution). See the [list of supported distributions](https://github.com/llamastack/llama-stack-k8s-operator/blob/main/distributions.json) in the operator repository.
- `server.distribution.image`: (Optional) Custom container image for non-supported distributions. Use this field when deploying a distribution that is not in the supported list. If specified, this takes precedence over `name`.
- `server.containerSpec.port`: Port on which the Llama Stack server listens (default: 8321)
- `server.containerSpec.env`: Environment variables to configure providers:
- `server.userConfig`: (Optional) Override the default `run.yaml` using a ConfigMap. See [userConfig spec](https://github.com/llamastack/llama-stack-k8s-operator/blob/main/docs/api-overview.md#userconfigspec).
- `server.storage.size`: Size of the persistent volume for model and data storage
- `server.storage.mountPath`: Where to mount the storage in the container
**Note:** For a complete list of supported distributions, see [distributions.json](https://github.com/llamastack/llama-stack-k8s-operator/blob/main/distributions.json) in the operator repository. To use a custom or non-supported distribution, set the `server.distribution.image` field with your container image instead of `server.distribution.name`.
The operator automatically creates:
- A Deployment for the Llama Stack server
- A Service to access the server
- A PersistentVolumeClaim for storage
- All necessary RBAC resources
Check the status of your deployment:
```bash
kubectl get llamastackdistribution
kubectl describe llamastackdistribution llamastack-vllm
```
### Step 5: Test Deployment
Wait for the Llama Stack server pod to be ready:
```bash
# Port forward and test
kubectl port-forward service/llama-stack-service 5000:5000
llama-stack-client --endpoint http://localhost:5000 inference chat-completion --message "hello, what model are you?"
# Check the status of the LlamaStackDistribution
kubectl get llamastackdistribution llamastack-vllm
# Check the pods created by the operator
kubectl get pods -l app.kubernetes.io/name=llama-stack
# Wait for the pod to be ready
kubectl wait --for=condition=ready pod -l app.kubernetes.io/name=llama-stack --timeout=300s
```
Get the service name created by the operator (it typically follows the pattern `<llamastackdistribution-name>-service`):
```bash
# List services to find the service name
kubectl get services | grep llamastack
# Port forward and test (replace SERVICE_NAME with the actual service name)
kubectl port-forward service/llamastack-vllm-service 8321:8321
```
In another terminal, test the deployment:
```bash
llama-stack-client --endpoint http://localhost:8321 inference chat-completion --message "hello, what model are you?"
```
## Troubleshooting
**Check pod status:**
### vLLM Server Issues
**Check vLLM pod status:**
```bash
kubectl get pods -l app.kubernetes.io/name=vllm
kubectl logs -l app.kubernetes.io/name=vllm
```
**Test service connectivity:**
**Test vLLM service connectivity:**
```bash
kubectl run -it --rm debug --image=curlimages/curl --restart=Never -- curl http://vllm-server:8000/v1/models
```
### Llama Stack Server Issues
**Check LlamaStackDistribution status:**
```bash
# Get detailed status
kubectl describe llamastackdistribution llamastack-vllm
# Check for events
kubectl get events --sort-by='.lastTimestamp' | grep llamastack-vllm
```
**Check operator-managed pods:**
```bash
# List all pods managed by the operator
kubectl get pods -l app.kubernetes.io/name=llama-stack
# Check pod logs (replace POD_NAME with actual pod name)
kubectl logs -l app.kubernetes.io/name=llama-stack
```
**Check operator status:**
```bash
# Verify the operator is running
kubectl get pods -n llama-stack-operator-system
# Check operator logs if issues persist
kubectl logs -n llama-stack-operator-system -l control-plane=controller-manager
```
**Verify service connectivity:**
```bash
# Get the service endpoint
kubectl get svc llamastack-vllm-service
# Test connectivity from within the cluster
kubectl run -it --rm debug --image=curlimages/curl --restart=Never -- curl http://llamastack-vllm-service:8321/health
```

# Llama Stack UI
The Llama Stack UI is a web-based interface for interacting with Llama Stack servers. Built with Next.js and React, it provides a visual way to work with agents, manage resources, and view logs.
## Features
- **Logs & Monitoring**: View chat completions, agent responses, and vector store activity
- **Vector Stores**: Create and manage vector databases for RAG (Retrieval-Augmented Generation) workflows
- **Prompt Management**: Create and manage reusable prompts
## Prerequisites
You need a running Llama Stack server. The UI is a client that connects to the Llama Stack backend.
If you don't have a Llama Stack server running yet, see the [Starting Llama Stack Server](../getting_started/starting_llama_stack_server.mdx) guide.
## Running the UI
### Option 1: Using npx (Recommended for Quick Start)
The fastest way to get started is using `npx`:
```bash
npx llama-stack-ui
```
This will start the UI server on `http://localhost:8322` (default port).
### Option 2: Using Docker
Run the UI in a container:
```bash
docker run -p 8322:8322 llamastack/ui
```
Access the UI at `http://localhost:8322`.
## Environment Variables
The UI can be configured using the following environment variables:
| Variable | Description | Default |
|----------|-------------|---------|
| `LLAMA_STACK_BACKEND_URL` | URL of your Llama Stack server | `http://localhost:8321` |
| `LLAMA_STACK_UI_PORT` | Port for the UI server | `8322` |
If the Llama Stack server is running with authentication enabled, you can configure the UI to use it by setting the following environment variables:
| Variable | Description | Default |
|----------|-------------|---------|
| `NEXTAUTH_URL` | NextAuth URL for authentication | `http://localhost:8322` |
| `GITHUB_CLIENT_ID` | GitHub OAuth client ID (optional, for authentication) | - |
| `GITHUB_CLIENT_SECRET` | GitHub OAuth client secret (optional, for authentication) | - |
### Setting Environment Variables
#### For npx:
```bash
LLAMA_STACK_BACKEND_URL=http://localhost:8321 \
LLAMA_STACK_UI_PORT=8080 \
npx llama-stack-ui
```
#### For Docker:
```bash
docker run -p 8080:8080 \
-e LLAMA_STACK_BACKEND_URL=http://localhost:8321 \
-e LLAMA_STACK_UI_PORT=8080 \
llamastack/ui
```
## Using the UI
### Managing Resources
- **Vector Stores**: Create vector databases for RAG workflows, view stored documents and embeddings
- **Prompts**: Create and manage reusable prompt templates
- **Chat Completions**: View history of chat interactions
- **Responses**: Browse detailed agent responses and tool calls
## Development
If you want to run the UI from source for development:
```bash
# From the project root
cd src/llama_stack_ui
# Install dependencies
npm install
# Set environment variables
export LLAMA_STACK_BACKEND_URL=http://localhost:8321
# Start the development server
npm run dev
```
The development server will start on `http://localhost:8322` with hot reloading enabled.

# OCI Distribution
The `llamastack/distribution-oci` distribution consists of the following provider configurations.
| API | Provider(s) |
|-----|-------------|
| agents | `inline::meta-reference` |
| datasetio | `remote::huggingface`, `inline::localfs` |
| eval | `inline::meta-reference` |
| files | `inline::localfs` |
| inference | `remote::oci` |
| safety | `inline::llama-guard` |
| scoring | `inline::basic`, `inline::llm-as-judge`, `inline::braintrust` |
| tool_runtime | `remote::brave-search`, `remote::tavily-search`, `inline::rag-runtime`, `remote::model-context-protocol` |
| vector_io | `inline::faiss`, `remote::chromadb`, `remote::pgvector` |
### Environment Variables
The following environment variables can be configured:
- `OCI_AUTH_TYPE`: OCI authentication type (instance_principal or config_file) (default: `instance_principal`)
- `OCI_REGION`: OCI region (e.g., us-ashburn-1, us-chicago-1, us-phoenix-1, eu-frankfurt-1) (default: ``)
- `OCI_COMPARTMENT_OCID`: OCI compartment ID for the Generative AI service (default: ``)
- `OCI_CONFIG_FILE_PATH`: OCI config file path (required if OCI_AUTH_TYPE is config_file) (default: `~/.oci/config`)
- `OCI_CLI_PROFILE`: OCI CLI profile name to use from config file (default: `DEFAULT`)
## Prerequisites
### Oracle Cloud Infrastructure Setup
Before using the OCI Generative AI distribution, ensure you have:
1. **Oracle Cloud Infrastructure Account**: Sign up at [Oracle Cloud Infrastructure](https://cloud.oracle.com/)
2. **Generative AI Service Access**: Enable the Generative AI service in your OCI tenancy
3. **Compartment**: Create or identify a compartment where you'll deploy Generative AI models
4. **Authentication**: Configure authentication using either:
- **Instance Principal** (recommended for cloud-hosted deployments)
- **API Key** (for on-premises or development environments)
### Authentication Methods
#### Instance Principal Authentication (Recommended)
Instance Principal authentication allows OCI resources to authenticate using the identity of the compute instance they're running on. This is the most secure method for production deployments.
Requirements:
- Instance must be running in an Oracle Cloud Infrastructure compartment
- Instance must have appropriate IAM policies to access Generative AI services
#### API Key Authentication
For development or on-premises deployments, follow [this doc](https://docs.oracle.com/en-us/iaas/Content/API/Concepts/apisigningkey.htm) to learn how to create your API signing key for your config file.
### Required IAM Policies
Ensure your OCI user or instance has the following policy statements:
```
Allow group <group_name> to use generative-ai-inference-endpoints in compartment <compartment_name>
Allow group <group_name> to manage generative-ai-inference-endpoints in compartment <compartment_name>
```
## Supported Services
### Inference: OCI Generative AI
Oracle Cloud Infrastructure Generative AI provides access to high-performance AI models through OCI's Platform-as-a-Service offering. The service supports:
- **Chat Completions**: Conversational AI with context awareness
- **Text Generation**: Complete prompts and generate text content
#### Available Models
Common OCI Generative AI models include access to Meta, Cohere, OpenAI, Grok, and more models.
### Safety: Llama Guard
For content safety and moderation, this distribution uses Meta's LlamaGuard model through the OCI Generative AI service to provide:
- Content filtering and moderation
- Policy compliance checking
- Harmful content detection
### Vector Storage: Multiple Options
The distribution supports several vector storage providers:
- **FAISS**: Local in-memory vector search
- **ChromaDB**: Distributed vector database
- **PGVector**: PostgreSQL with vector extensions
### Additional Services
- **Dataset I/O**: Local filesystem and Hugging Face integration
- **Tool Runtime**: Web search (Brave, Tavily) and RAG capabilities
- **Evaluation**: Meta reference evaluation framework
## Running Llama Stack with OCI
You can run the OCI distribution via Docker or local virtual environment.
### Via venv
If you've set up your local development environment, you can also build the image using your local virtual environment.
```bash
OCI_AUTH=$OCI_AUTH_TYPE OCI_REGION=$OCI_REGION OCI_COMPARTMENT_OCID=$OCI_COMPARTMENT_OCID llama stack run --port 8321 oci
```
### Configuration Examples
#### Using Instance Principal (Recommended for Production)
```bash
export OCI_AUTH_TYPE=instance_principal
export OCI_REGION=us-chicago-1
export OCI_COMPARTMENT_OCID=ocid1.compartment.oc1..<your-compartment-id>
```
#### Using API Key Authentication (Development)
```bash
export OCI_AUTH_TYPE=config_file
export OCI_CONFIG_FILE_PATH=~/.oci/config
export OCI_CLI_PROFILE=DEFAULT
export OCI_REGION=us-chicago-1
export OCI_COMPARTMENT_OCID=ocid1.compartment.oc1..your-compartment-id
```
## Regional Endpoints
OCI Generative AI is available in multiple regions. The service automatically routes to the appropriate regional endpoint based on your configuration. For a full list of regional model availability, visit:
https://docs.oracle.com/en-us/iaas/Content/generative-ai/overview.htm#regions
## Troubleshooting
### Common Issues
1. **Authentication Errors**: Verify your OCI credentials and IAM policies
2. **Model Not Found**: Ensure the model OCID is correct and the model is available in your region
3. **Permission Denied**: Check compartment permissions and Generative AI service access
4. **Region Unavailable**: Verify the specified region supports Generative AI services
### Getting Help

In contrast, the [Llama Stack documentation](https://llamastack.github.io/docs/api/create-a-new-open-ai-response) says that the allowed values for `type` for web search are `MOD1`, `MOD2` and `MOD3`.
Is that correct? If so, what are the meanings of each of them? It might make sense for the allowed values for OpenAI map to some values for Llama Stack so that code written to the OpenAI specification

Llama Stack now supports both `web_search` and `web_search_2025_08_26` types, matching OpenAI's API. For backward compatibility, Llama Stack also supports `web_search_preview` and `web_search_preview_2025_03_11` types.
The OpenAI web search tool also has fields for `filters` and `user_location` which are not documented as options for Llama Stack. If feasible, it would be good to support these too.

# OCI Distribution
The `llamastack/distribution-{{ name }}` distribution consists of the following provider configurations.
{{ providers_table }}
{% if run_config_env_vars %}
### Environment Variables
The following environment variables can be configured:
{% for var, (default_value, description) in run_config_env_vars.items() %}
- `{{ var }}`: {{ description }} (default: `{{ default_value }}`)
{% endfor %}
{% endif %}
{% if default_models %}
### Models
The following models are available by default:
{% for model in default_models %}
- `{{ model.model_id }} {{ model.doc_string }}`
{% endfor %}
{% endif %}
## Prerequisites
### Oracle Cloud Infrastructure Setup
Before using the OCI Generative AI distribution, ensure you have:
1. **Oracle Cloud Infrastructure Account**: Sign up at [Oracle Cloud Infrastructure](https://cloud.oracle.com/)
2. **Generative AI Service Access**: Enable the Generative AI service in your OCI tenancy
3. **Compartment**: Create or identify a compartment where you'll deploy Generative AI models
4. **Authentication**: Configure authentication using either:
- **Instance Principal** (recommended for cloud-hosted deployments)
- **API Key** (for on-premises or development environments)
### Authentication Methods
#### Instance Principal Authentication (Recommended)
Instance Principal authentication allows OCI resources to authenticate using the identity of the compute instance they're running on. This is the most secure method for production deployments.
Requirements:
- Instance must be running in an Oracle Cloud Infrastructure compartment
- Instance must have appropriate IAM policies to access Generative AI services
#### API Key Authentication
For development or on-premises deployments, follow [this doc](https://docs.oracle.com/en-us/iaas/Content/API/Concepts/apisigningkey.htm) to learn how to create your API signing key for your config file.
### Required IAM Policies
Ensure your OCI user or instance has the following policy statements:
```
Allow group <group_name> to use generative-ai-inference-endpoints in compartment <compartment_name>
Allow group <group_name> to manage generative-ai-inference-endpoints in compartment <compartment_name>
```
## Supported Services
### Inference: OCI Generative AI
Oracle Cloud Infrastructure Generative AI provides access to high-performance AI models through OCI's Platform-as-a-Service offering. The service supports:
- **Chat Completions**: Conversational AI with context awareness
- **Text Generation**: Complete prompts and generate text content
#### Available Models
Common OCI Generative AI models include access to Meta, Cohere, OpenAI, Grok, and more models.
### Safety: Llama Guard
For content safety and moderation, this distribution uses Meta's LlamaGuard model through the OCI Generative AI service to provide:
- Content filtering and moderation
- Policy compliance checking
- Harmful content detection
### Vector Storage: Multiple Options
The distribution supports several vector storage providers:
- **FAISS**: Local in-memory vector search
- **ChromaDB**: Distributed vector database
- **PGVector**: PostgreSQL with vector extensions
### Additional Services
- **Dataset I/O**: Local filesystem and Hugging Face integration
- **Tool Runtime**: Web search (Brave, Tavily) and RAG capabilities
- **Evaluation**: Meta reference evaluation framework
## Running Llama Stack with OCI
You can run the OCI distribution via Docker or local virtual environment.
### Via venv
If you've set up your local development environment, you can also build the image using your local virtual environment.
```bash
OCI_AUTH=$OCI_AUTH_TYPE OCI_REGION=$OCI_REGION OCI_COMPARTMENT_OCID=$OCI_COMPARTMENT_OCID llama stack run --port 8321 oci
```
### Configuration Examples
#### Using Instance Principal (Recommended for Production)
```bash
export OCI_AUTH_TYPE=instance_principal
export OCI_REGION=us-chicago-1
export OCI_COMPARTMENT_OCID=ocid1.compartment.oc1..<your-compartment-id>
```
#### Using API Key Authentication (Development)
```bash
export OCI_AUTH_TYPE=config_file
export OCI_CONFIG_FILE_PATH=~/.oci/config
export OCI_CLI_PROFILE=DEFAULT
export OCI_REGION=us-chicago-1
export OCI_COMPARTMENT_OCID=ocid1.compartment.oc1..your-compartment-id
```
## Regional Endpoints
OCI Generative AI is available in multiple regions. The service automatically routes to the appropriate regional endpoint based on your configuration. For a full list of regional model availability, visit:
https://docs.oracle.com/en-us/iaas/Content/generative-ai/overview.htm#regions
## Troubleshooting
### Common Issues
1. **Authentication Errors**: Verify your OCI credentials and IAM policies
2. **Model Not Found**: Ensure the model OCID is correct and the model is available in your region
3. **Permission Denied**: Check compartment permissions and Generative AI service access
4. **Region Unavailable**: Verify the specified region supports Generative AI services
### Getting Help
For additional support:
- [OCI Generative AI Documentation](https://docs.oracle.com/en-us/iaas/Content/generative-ai/home.htm)
- [Llama Stack Issues](https://github.com/meta-llama/llama-stack/issues)
