Best estimate from public evidence; the vendor did not disclose every value. Z.ai's legal-domain variant of GLM-5.3-FlashX with extra legal mid-training and RL post-training; no weights are published. Counts are inherited from the FlashX record (320B total / 18B active MoE) because domain post-training is not reported to change the backbone.
