| # Azure Cosmos DB .NET SDK AI Extension Library | ||
|
|
||
| `Microsoft.Azure.Cosmos.AI` is an optional, provider-style extension package for the [Azure Cosmos DB .NET SDK](https://www.nuget.org/packages/Microsoft.Azure.Cosmos/) that adds AI-powered capabilities to applications built on Azure Cosmos DB for NoSQL. | ||
|
|
||
| > **Status:** This package is in early development. It currently ships as a scaffold only — no public APIs are exposed yet. The first capability (an `AzureOpenAIEmbeddingGenerator` provider for automatic vector embedding generation in hybrid and vector search queries) is tracked in [#5842](https://github.com/Azure/azure-cosmos-dotnet-v3/pull/5842). Breaking changes may occur prior to GA. | ||
|
|
||
| ## Why a Separate Package | ||
|
|
||
| - **Zero cost for non-AI workloads.** Applications that don't use AI features pull in no AI dependencies. `Azure.AI.OpenAI` and related dependencies are only present for customers who explicitly opt in to this package. | ||
| - **Independent versioning.** This package ships on its own cadence, allowing rapid iteration on AI capabilities without coupling to the core SDK release cycle. | ||
| - **Established extensibility model.** Follows the same pattern proven by `Microsoft.Azure.Cosmos.Encryption` — a separate, optional, provider-style package that extends the core SDK without polluting it. | ||
| - **Clear separation of concerns.** The core SDK owns the data plane. This package owns AI service integration. | ||
|
|
||
| ## Planned Capabilities | ||
|
|
||
| - **Automatic vector embedding generation** — provide raw text to vector / hybrid search queries; the SDK calls a configured embedding service (e.g., Azure OpenAI) on your behalf. | ||
| - **Semantic re-ranking** — re-rank query results using AI services. | ||
| - **AI-assisted query construction** — generate Cosmos DB queries from natural language. | ||
| - Additional AI-powered features as the landscape evolves. | ||
|
|
||
| ## Getting Started | ||
|
|
||
| Once the first capability lands in a published preview, install from NuGet: | ||
|
|
||
| ```bash | ||
| dotnet add package Microsoft.Azure.Cosmos.AI --prerelease | ||
| ``` | ||
|
|
||
| Usage examples will be added here as APIs ship. | ||

There was a problem hiding this comment. Done in db7ea2e — both Microsoft.Azure.Cosmos.AI and Microsoft.Azure.Cosmos.AI.Tests are now in Microsoft.Azure.Cosmos.sln under a new AI solution folder (mirrors the existing Encryption / Encryption.Custom folders). Verified locally with dotnet build Microsoft.Azure.Cosmos.sln -p:IsPreview=true -p:SdkProjectRef=true --configuration Release — 0 errors, 16 pre-existing warnings (all Microsoft.Azure.Cosmos.Performance.Tests net6.0 EOL warnings, unrelated). This now means every PR build that runs the solution will catch core-SDK changes that break the AI package, same as the Encryption guardrail. |

There was a problem hiding this comment. Two artifacts worth seeding now, before the first preview push to nuget.org:
Both are essentially free at the scaffold stage and load-bearing once the package is on nuget.org.

There was a problem hiding this comment. This makes three copies of the same hard-coded test public key in the repo (Encryption, Encryption.Custom, and now AI), all under "Mirrored" folders with no canonical source. If the key is ever rotated, three files diverge. Out of scope for this PR, but worth a follow-up: extract a single

There was a problem hiding this comment. Agreed and noted — leaving the 3 Mirrored\AssemblyKeys.cs copies as-is in this PR per your out-of-scope call. I'll file a follow-up issue to extract a single canonical AssemblyKeys.cs under Microsoft.Azure.Cosmos/build/ and it from all three packages (Encryption, Encryption.Custom, AI), and link the issue from this thread once filed. |
