# Reproduce the September 2026 BaZi chart check

The dataset contains 60 archived model responses to 12 fictional Hong Kong births. It includes prompts, answers, extracted pillars and our engine's reference pillars. These are recorded model versions with web search disabled, not a benchmark of today's assistants or a test of interpretive accuracy.

Download the [JSON dataset](https://www.kaucim.ai/data/bazi-chart-check-2026-09.json), the [CSV comparison](https://www.kaucim.ai/data/bazi-chart-check-2026-09.csv), and the [summary module](https://www.kaucim.ai/downloads/bazi-chart-check.mjs). None requires an API key or payment. The method and limits are visible on the [English report](https://www.kaucim.ai/en/bazi/ai-chart-check) and [Chinese report](https://www.kaucim.ai/bazi/ai-chart-check).

To recompute the published totals in a browser console or a JavaScript project, place the module next to your script and run the following.

```js
import { summarizeChartCheck } from './bazi-chart-check.mjs';
const response = await fetch('https://www.kaucim.ai/data/bazi-chart-check-2026-09.json');
if (!response.ok) throw new Error(`Dataset unavailable: ${response.status}`);
const data = await response.json();
console.table(summarizeChartCheck(data));
```

For an individual check, read a record's full answer and compare its extracted pillars to its reference pillars in year, month, day, hour order. The export's extraction rule can select explanatory text, so review the answer when interpreting a mismatch. An answer with missing pillars remains in the denominator and is counted separately as incomplete. A match to our engine does not establish agreement among all schools.

To inspect the reference with the [free BaZi chart](https://www.kaucim.ai/en/bazi?from=bazi-chart-check-example), enter the fictional date, gender and two-hour branch in the record. Keep clock time, with no solar correction. The cases avoid Zi-hour and solar-term month boundaries. Compare the four pillars only; current luck-cycle labels change with today's date.

The [developer resources](https://www.kaucim.ai/developers) list the supported public interfaces. This package reads public fixtures and never uploads a visitor's birth data, creates a chart profile or initiates a purchase.
