Last I checked - DALL-E 1 is ~12 Billion parameters. DALL-E 2 is about 3 or 4B, much smaller. If you look on openAI.com you can see examples of DALL-E 1 in action, it does prompts shown better than DALL-E 2’s attempts at them (I tried, they are not shown on their site therefore), including any text printing one. I’ve tried this, I’m certain.
It would earn OpenAI cash if they try putting up DALL-E 1 in Playground, maybe it will earn more than they think or people will pay more to use it still! Gotta try!
