TypeSafe's Jev Points to a New Class of Non-Text AI Models

TypeSafe AI released Jev, a "System One" model that does not generate text, on September 15, and more than a dozen similar models from OpenAI, Cloudflare, Perplexity and open-source projects followed within three weeks. Liquid AI added another new model class on October 27, small enough to run on a phone. The author argues that model selection is shifting from choosing among LLMs of different sizes to matching different model types to different tasks.

Why it matters: Teams designing AI agents will need to choose among non-generative models for fast, deterministic decisions as well as LLMs for generative work, which changes architecture and cost planning.
