+
+### Minor Changes
+
+- [#812](https://github.com/preactjs/signals/pull/812) [`19ac39b`](https://github.com/preactjs/signals/commit/19ac39bb4a7a3273090753a50a58efb717f5553d) Thanks [@andrewiggins](https://github.com/andrewiggins)! - Add `createModel` and `action` to signals core package
+
+  **`createModel`** provides a structured way to create reactive model classes that encapsulate signals, computed values, and actions:
+
+  ```js
+  const CounterModel = createModel((initialCount = 0) => {
+  	const count = signal(initialCount);
+  	const doubled = computed(() => count.value * 2);
+
+  	effect(() => {
+  		console.log("Count changed:", count.value);
+  	});
+
+  	return {
+  		count,
+  		doubled,
+  		increment() {
+  			count.value++;
+  		},
+  	};
+  });
+
+  const counter = new CounterModel(5);
+  counter.increment(); // Updates are automatically batched
+  counter[Symbol.dispose](); // Cleans up all effects
+  ```
+
+  Key features:
+  - Factory functions can accept arguments for initialization
+  - All methods are automatically wrapped as actions (batched & untracked)
+  - Effects created during model construction are captured and disposed when the model is disposed via `Symbol.dispose`
+  - TypeScript validates that models only contain signals, actions, or nested objects with signals/actions
+
+  **`action`** is a helper that wraps a function to run batched and untracked:
+
+  ```js
+  const updateAll = action(items => {
+  	items.forEach(item => item.value++);
+  }); // All updates batched into single notification
+  ```
+

+/**
+ * The public types for ModelConstructor require using `new` to help
+ * disambiguate the function passed into `createModel` and the returned
+ * constructor function. It is easier to say that `createModel` accepts
+ * a factory and returns a class, then to say it accepts a factory and
+ * returns a factory. In other words, this example:
+ *
+ * ```ts
+ * const PersonModel = createModel((name: string) => ({ ... }));
+ * const person = new PersonModel("John");
+ * ```
+ *
+ * is easier to understand than this example:
+ *
+ * ```ts
+ * const createPerson = createModel((name: string) => ({ ... }));
+ * const person = createPerson("John");
+ * ```
+ *
+ * However, internally we implement `createModel` to return a function
+ * that can be called without `new` for simplicity. To bridge the gap
+ * between the public types and the internal implementation, we define
+ * this internal interface that extends the public interface but also
+ * allows calling without `new`.
+ *
+ * This pattern is used by the Preact & React adapters to make instantiating
+ * a model or a function that returns a model easier.
