Sword Health releases Dawn 1, a mental health support model built on GLM-5.3

Sword Health releases Dawn 1, a mental health support model it built by post-training GLM-5.3 with reinforcement learning on Prime Intellect's prime-rl framework, according to Prime Intellect's announcement.

Sword says Dawn 1 delivers greater intelligence at lower inference cost than its base model, with strong performance across mental health knowledge, safety and sycophancy evaluations.

Sword's own announcement says Dawn 1 is safer and less sycophantic than the base model and outperforms frontier proprietary models on multi-turn safety protocol adherence in Sword's evaluations. These results come from Sword's own testing and have not been independently verified.
