Last week, OpenAI opened up DALL-E 3, its premier image generation model, to all Plus and Enterprise ChatGPT users. While image generation models in the past have been an amusing play toy, this new model marries a new powerful image model with the GPT-4’s ability to craft fine tuned prompts that best suit it. Combined, the two now enable ChatGPT users to generate a wide variety of highly detailed original images in various styles.
Among those, logos. Something that seemed almost impossible with past image generation models is now fun and easy with GPT-4 and DALL-E 3 in ChatGPT. By just having a conversation with ChatGPT, anyone can put together a useable logo in 10 minutes or less.
The Pitch Meeting with GPT-4
Because of how intimately the prompts between the two models work together, it’s worth having GPT-4 generate a starting prompt before engaging with DALL-E 3. Remember, GPT-4 acts as the mediator, translating your vague ideas into precise prompts that DALL-E 3 can interpret.
Let’s say I’m working on starting a new coffee shop, and need a digital logo for our website (that I’ll eventually want to put on my brick and mortar store as well). My coffee shop’s name is “Azalea Brew”, so I know that I vaguely want some azalea and coffee theming.
I’ll start by throwing my embryonic idea at GPT-4—something like "Give me a prompt optimized for DALL-E 3 to generate a logo for a coffee shop with floral, azalea theming."
GPT-4 whipped out a more elaborate, fine-tuned prompt. It might say, "Generate a logo for a coffee shop that incorporates floral and azalea elements. The design should evoke a warm and inviting atmosphere while highlighting the unique azalea theme. Include a steaming coffee cup as the central focus, surrounded by azalea flowers and leaves. Opt for a color palette that harmonizes well with deep coffee browns and vibrant azalea pinks." This prompt carries substantial weight, loaded with nuanced instructions that can set DALL-E 3 exactly on the path we want.
Finetuning DALL-E 3’s First Iteration
Armed with your enhanced prompt, you're ready for the main event: a virtual logo design meeting with DALL-E 3. Initially, being specific about what you definitely want in your logo is key. Add some of the below keywords to the end of your GPT-4 generated prompt to ensure things are generated properly.
