One-sentence 3D HTML game (NEON RUNNER)

How to use it

Models / tools: DeepSeek V4.1 Flash-1017

1. Send the line to an AI coding agent that can write files and see what game it hands back.

What it can do

This is the one-sentence prompt Michael Leung used on his blog to test a new DeepSeek model. The whole prompt is a single line asking for a simple, standalone 3D HTML game, with the type of game left to the model. The author says DeepSeek V4.1 Flash-1017, running in DeepSeek Harness, turned that line into NEON RUNNER, an endless runner. What sets it apart is how short it is: it takes almost no setup to compare whether different models or coding tools can finish a small piece of work on their own. Send the line to an AI coding agent that can write files and see what game it hands back.

Who it is for

Anyone who wants to compare models or coding tools using the same single line.

Before you use it

The author used DeepSeek V4.1 Flash-1017 with DeepSeek Harness, and other models will give different results. The time and cost the author recorded come from one test of his own.
