TypeSafe AI's Jev Is Not an LLM – and That May Be the Point
By abandoning the generative capabilities of LLMs in favor of a non-LLM architecture, TypeSafe aims to replace the expensive, latency-prone routing and classification tasks that currently dominate agent pipelines. An OpenAI Veteran’s Bet Against LLMs At the helm of TypeSafe AI is CEO Diogo Almeida, an OpenAI veteran and co-inventor of RLHF, whose work was foundational to the development of InstructGPT and GPT-4. Alongside co-founders Erik Gafni and Sasha Sheng, Almeida has built Jev on a parallel sampling architecture.

By abandoning the generative capabilities of LLMs in favor of a non-LLM architecture, TypeSafe aims to replace the expensive, latency-prone routing and classification tasks that currently dominate agent pipelines.
