+# How AI Models Draw a Python Reading a Book
+
+Sample code for Real Python's [vibe check for new AI models](https://realpython.com/ai-benchmark/). Every new model gets the same fixed prompt, *Write a Python turtle program that draws a python reading a book*, and the result is published as is, drawing and all.
+
+Each subfolder is one model's run, named after the model id without its vendor prefix. It contains the turtle script exactly as the model returned it, the rendered drawing, the animation of the turtle drawing it, and a README with the details of that run.
+
+| Folder | Write-up |
+|---|---|
+| [`gpt-6-astra/`](gpt-6-astra/) | [GPT-6 Astra Draws a Python Reading a Book](https://realpython.com/ai-benchmark-gpt-6-astra/) |
+
+The scripts are the models' output verbatim and are excluded from this repository's Ruff checks on purpose. Nothing was fixed up; that's the point.

+# GPT-6 Astra Draws a Python Reading a Book
+
+This folder holds the sample code for the Real Python write-up [GPT-6 Astra Draws a Python Reading a Book](https://realpython.com/ai-benchmark-gpt-6-astra/), part of [How AI Models Draw a Python Reading a Book](https://realpython.com/ai-benchmark/).
+
+- Model: `openai/gpt-6-astra`, at its default reasoning settings, run on 2026-09-04
+- Prompt: *Write a Python turtle program that draws a python reading a book.*
+
+## What's Here
+
+| File | What |
+|---|---|
+| `gpt-6-astra-python-reading-a-book.py` | The turtle script, exactly as the model returned it, with a header naming the model, date, and prompt |
+| `gpt-6-astra-python-reading-a-book.png` | The finished drawing, rendered headlessly at 800×600 |
+| `gpt-6-astra-python-reading-a-book.gif` | The turtle drawing it, frame by frame |
+
+## Run It
+
+You need Python with `tkinter`, which ships with the standard installers from python.org:
+
+```sh
+$ python gpt-6-astra-python-reading-a-book.py
+```
+
+A window opens and the turtle draws the picture. Change a color, a coordinate, or the caption and run it again to see what the model's code is actually doing. To learn the module from scratch, start with [The Beginner's Guide to Python's turtle Module](https://realpython.com/beginners-guide-python-turtle/).
+
+## A Note on the Code
+
+Nothing in the script was fixed up. It's the model's output verbatim, so it isn't formatted to this repository's Ruff rules on purpose. That's part of what the write-up reads off it.
