OpenAI hosting integration

यह कंटेंट अभी तक आपकी भाषा में उपलब्ध नहीं है।

The hosting integration models OpenAI with two resource types:

OpenAIResource: Parent that holds the shared API key and base endpoint (defaults to https://api.openai.com/v1).
OpenAIModelResource: Child representing a specific model; composes a connection string from the parent (Endpoint + Key + Model).

To access these types and APIs, install the 📦 Aspire.Hosting.OpenAI NuGet package in your AppHost project:

aspire add openai

<PackageReference Include="Aspire.Hosting.OpenAI" Version="*" />

Add an OpenAI parent resource

var builder = DistributedApplication.CreateBuilder(args);

var openai = builder.AddOpenAI("openai");

builder.AddProject<Projects.ExampleProject>()
       .WithReference(openai);

// After adding all resources, run the app...

Add OpenAI model resources

Add one or more model children beneath the parent and reference them from projects:

var builder = DistributedApplication.CreateBuilder(args);

var openai = builder.AddOpenAI("openai");

var chat = openai.AddModel("chat", "gpt-4o-mini");
var embeddings = openai.AddModel("embeddings", "text-embedding-3-small");

builder.AddProject<Projects.ExampleProject>()
       .WithReference(chat);

// After adding all resources, run the app...

Referencing chat passes a connection string named chat to the project. Multiple models can share the single API key and endpoint via the parent resource.

Use default API key parameter

Calling AddOpenAI("openai") creates a secret parameter named openai-openai-apikey. Aspire resolves its value in this order:

The Parameters:openai-openai-apikey configuration key (user secrets, appsettings.*, or environment variables).
The OPENAI_API_KEY environment variable.

If neither source provides a value, startup throws an exception. Provide the key via the Aspire CLI:

aspire secret set Parameters:openai-openai-apikey sk-your-api-key

Use custom API key parameter

Replace the default parameter by creating your own secret parameter and calling WithApiKey on the parent:

var builder = DistributedApplication.CreateBuilder(args);

var apiKey = builder.AddParameter("my-api-key", secret: true);

var openai = builder.AddOpenAI("openai")
                    .WithApiKey(apiKey);

var chat = openai.AddModel("chat", "gpt-4o-mini");

builder.AddProject<Projects.ExampleProject>()
       .WithReference(chat);

Add a custom endpoint

Override the default endpoint (for example to use a proxy or compatible gateway):

var builder = DistributedApplication.CreateBuilder(args);

var openai = builder.AddOpenAI("openai")
                    .WithEndpoint("https://my-gateway.example.com/v1");

var chat = openai.AddModel("chat", "gpt-4o-mini");

builder.AddProject<Projects.ExampleProject>()
       .WithReference(chat);

Health checks

Add an optional single-run health check per model when diagnosing issues:

var chat = builder.AddOpenAI("openai")
                  .AddModel("chat", "gpt-4o-mini")
                  .WithHealthCheck();

The model health check validates endpoint reachability, API key validity (401), and model existence (404). It executes only once per application instance to limit rate-limit implications. A status-page check against https://status.openai.com/api/v2/status.json is automatically registered for each parent resource.
