The Shift from Model Building to AI Applications

Early in the AI race, apps like Perplexity, Cursor, Sesame and Abridge were known pejoratively as “wrappers,” describing the way their either app or business was wrapped around existing AI models. Critics called them as second-rate middlemen, slapping an interface on someone else’s technology while companies like OpenAI, Google, Meta and Anthropic developed their own models. Now, that thesis is changing. Wrappers have changed the way Silicon Valley builds, ushering in the era of vibe-coding.
