 Decision models like [Jev](https://openrouter.ai/typesafe/jev-1.13) are built for this. They answer in a fraction of a second, cost a fraction of a cent per request, and return a probability instead of free text. That makes them fast and cheap enough to run on every CI build, and predictable enough to keep in a test.

 It uses a [decision model](https://openrouter.ai/models?output_modalities=decisions) like [Jev](https://openrouter.ai/typesafe/jev-1.13) instead of a chat model. A decision model reads the page and returns the probability that a statement is true.

+### Custom Decisions
+
+`I.decide` asks yes/no questions. AI SDK decisions also support `choice` and `score` questions. Use [`experimental_decide`](https://ai-sdk.dev/docs/ai-sdk-core/decisions) in a [custom helper](/helpers) to ask them about the current page:
+
+```js
+import Helper from '@codeceptjs/helper'
+import { experimental_decide as decide } from 'ai'
+import { createOpenRouter } from '@openrouter/ai-sdk-provider'
+
+class PageDecisions extends Helper {
+  async grabPageKind() {
+    const { Playwright } = this.helpers
+    const openrouter = createOpenRouter()
+
+    const { answers } = await decide({
+      model: openrouter.evaluationModel('typesafe/jev-1.13'),
+      state: {
+        url: await Playwright.grabCurrentUrl(),
+        aria: await Playwright.grabAriaSnapshot(),
+      },
+      questions: {
+        page: {
+          type: 'choice',
+          instructions: 'What kind of page is shown?',
+          criteria: { login: 'sign in form', dashboard: 'user dashboard', error: 'error message' },
+        },
+      },
+    })

+    return answers.page.choice
+  }
+}
+
+export default PageDecisions
+```
+
+```js
+const kind = await I.grabPageKind()
+```
+
+`ai` and `@openrouter/ai-sdk-provider` are installed with CodeceptJS. A `score` question returns a fractional position on a list of levels, and a `boolean` question returns a probability. See [AI SDK decisions](https://ai-sdk.dev/docs/ai-sdk-core/decisions) for all question types.
