OpenAI's creative team used Codex to generate 50 campaign directions in a single day

The biggest misconception about OpenAI’s Codex is that it’s just for engineers. Chad Nelson, a Creative Specialist at OpenAI, is demolishing that assumption by using the tool as his primary ideation partner—and what he’s finding should make any creative director sit up and pay attention.

Nelson’s job is inherently meta: he explores what OpenAI’s models can do for creative teams, then turns those findings into demos and workflows for brand partners. But he stumbled onto something surprising when he started feeding Codex non-technical inputs. “I’m actually bringing Codex sketches, storyboards, and design style guides—things that you wouldn’t assume Codex could understand,” Nelson says. “But it not only understands those things, it actually helps me collaborate and create utilizing those different assets.”

Traditional creative software has a fundamental blindness. As Nelson puts it, “The tools I’ve been using my whole career have no idea what project I’m on, what brand I’m working for, what product I’m trying to pitch.” Codex doesn’t have that problem. It can ingest brand books, style guides, font preferences, and strategic goals, then work across all of that context simultaneously. That’s not a minor upgrade—it’s a different category of tool.

The speed implications are hard to ignore. When Nelson needed to pitch a new client with just one day of runway, he didn’t settle for five or ten ideas. He fed Codex the brand context, product details, and desired tone, then riffed with it. The result? Fifty campaign directions in a single day, which he then curated down to the ten strongest. Under a normal deadline, many of those ideas would have been variations on the same theme. Here, the range was genuinely broad. For Nelson, the real unlock isn’t just velocity—it’s the freedom to explore tangents without penalty, knowing you can still hit the deadline with a stronger, more varied shortlist than you’d produce in a week of manual concepting.
