A GPT-5.6 creative-coding experiment

The ThinkRun story,
40 ways.

ThinkRun was built across 323 days. We wanted to see how well GPT-5.6 could turn that same development record into a compelling launch story—and whether more reasoning effort produced better results. So GPT-5.6 Sol and Terra each received the same repository context and creative brief 20 times. These are all 40 outcomes, including the runs that produced no page.

01 Each poster is one independent run 02 Open it to inspect the real webpage 03 “Failed run” means no page was produced
The result

Here’s what we learned.

Higher reasoning effort did not make this task more reliable. The clearest way to judge creative quality is to open the same brief’s outputs and decide which story you would ship.

19/20Medium-effort runs shipped

Only one medium-effort run ended without a webpage.

14/20High-effort runs shipped

Six high-effort runs produced no reviewable page.

+60%More normalized usage at high effort

$25.13 at high effort versus $15.75 at medium.

Source context

What the model could inspect before it designed.

Every run received the same history-free snapshot of the relevant ThinkRun working repository. The model chose which material to read and how to turn it into a story.

Design system + tokensThinkRun colors, typography, interface patterns, and visual references.
Website + frontendCurrent product pages, UI assets, product language, and frontend structure.
Docs + product blogFeature explanations, positioning, technical documentation, and published narratives.
Development memory wikiVerified milestones, dates, incidents, decisions, corrections, and lessons from the build.
Selected project codeRepository structure and lightweight source/configuration relevant to the product story.
One identical creative briefBuild one self-contained ThinkRun launch-story page; invent no statistics.
Anti-copy controls: prior generated story pages, git branches/history, recordings, dependency folders, agent transcripts, and heavy service/build directories were removed. Every statistic in a page was required to come from the supplied docs or memory.
