The two corpora cover overlapping sessions but different rendering choices in formatting, so they contribute distinct training rows. ## Why combined for v2 Training Qwable-v2 on the union teaches the model both styles: - With-`` rows reinforce reasoning-first behavior (~46% of corpus) - Without-`` rows reinforce direct-action behavior (~54% of corpus) In production, the model should produce reasoning when helpful (long planning) and skip it when the action is obvious. The mixed corpus is the closest thing to that distribution we have. ## Row format Same single-`text`-column Qwen chat template as v1, but the assistant block may or may not have a `...` prefix depending on the source row. ## License & terms Inherits **AGPL-3.0** from both upstream corpora. Same Anthropic usage-policy considerations apply.
