Z.ai said it adjusted GLM-5.3's rollout after partners asked for broader framework compatibility ahead of launch. The company said the change applies to the model's open-weight release and is meant to ensure it is properly supported and works reliably at launch.

Earlier on Wednesday, Z.ai had said GLM-5.3's weights would be released the next day, a message that was also reposted by Hugging Face. The later update did not provide a new release date.
