Dev breaks down paper: multi-harness training and environment synthesis principles
tokenbender · x · 2026-09-22
A developer shares paper takeaways: training with multiple harnesses (section 4.2.5) is a good idea since open source users have no single favorite and often build their own task-specific harnesses; the environment synthesis part also follows solid general principles of data synthesis — nice specs, sampling from a rich pool of real-world scenarios, curating good seed tasks and grounding in them. Details may vary by setup, but these principles are non-negotiable.
