Tigris Data uses AI-generated illustrations featuring their mascot Ty the tiger for blog post cover images. The creative process involves distilling a post's key insight into visual concepts, then iteratively refining prompts with GPT-4's image generation model. To streamline this workflow, they built Tygen, an open-source tool using Go, HTMX, OpenAI API, and Postgres that automates image generation and stores outputs in Tigris object storage.
