The release formalizes a stability contract with semantic versioning for a stable core and a separate experimental layer for newer methods. The design philosophy deliberately avoids deep abstractions and class hierarchies in favor of explicit, duplicated implementations that are easier to evolve as the field shifts. Upcoming work includes asynchronous GRPO for better GPU utilization, graduating KTO and distillation trainers to stable, improved multi-node scaling with MoE support, and embedding structured training diagnostics that surface actionable warnings for both humans and agents. ## Full article daily.dev links to this article rather than hosting it.
