-Support non-identified schemas in `Completions.structured`
+Support non-identified schemas in `AiChat.structured` and `Completions.structured`.
+
+Instead of requiring a `Schema` with either an `identifier` or `_tag` property
+for AI APIs that allow for returning structured outputs, you can now optionally
+pass a `correlationId` to `AiChat.structured` and `Completions.structured` when
+you want to either use a simple schema or inline the schema.
+
+Example:
+
+```ts
+import { Completions } from "@effect/ai"
+import { OpenAiClient, OpenAiCompletions } from "@effect/ai-openai"
+import { NodeHttpClient } from "@effect/platform-node"
+import { Config, Effect, Layer, Schema, String } from "effect"
+
+// Create the OpenAI client
+const OpenAi = OpenAiClient.layerConfig({
+  apiKey: Config.redacted("OPENAI_API_KEY")
+}).pipe(Layer.provide(NodeHttpClient.layerUndici))
+
+// Create an embeddings service for the `text-embedding-3-large` model
+const Gpt4oCompletions = OpenAiCompletions.layer({
+  model: "gpt-4o"
+}).pipe(Layer.provide(OpenAi))
+
+const program = Effect.gen(function*() {
+  const completions = yield* Completions.Completions
+
+  const CalendarEvent = Schema.Struct({
+    name: Schema.String,
+    date: Schema.DateFromString,
+    participants: Schema.Array(Schema.String)
+  })
+
+  yield* completions.structured({
+    correlationId: "CalendarEvent",
+    schema: CalendarEvent,
+    input: String.stripMargin(`
+      |Extract event information from the following prose:
+      |
+      |Alice and Bob are going to a science fair on Friday.
+    `)
+  })
+})
+
+program.pipe(
+  Effect.provide(Gpt4oCompletions),
+  Effect.runPromise
+)
+```
