Dev Says Frontier Lab's Jev Architecture Mirrors His Open-Source Work From a Year Ago

- An indie developer claims he built and fully open-sourced an architecture strikingly similar to Jev's newly hyped non-autoregressive, schema-based fast probability prediction—in March 2025, with an arXiv paper, model, dataset, and pypi package.
- His method uses RL (PPO over sequence embeddings) to output turn-by-turn 0.0-1.0 conversion probability trajectories; his second paper (Sept 2025) also anticipates the idea. Jev instead uses parallel sampling trained via RLCD, but shipped no technical paper, open weights, or dataset.
- He laments that open-source work goes unrecognized once a frontier lab productizes it horizontally; his earlier post was removed by Reddit filters. Links: arXiv 2503.23303, 2510.01237, HuggingFace.
