MindLab open-sources Macaron-V1, a GLM-5.2 family built on continual learning

MindLab has open-sourced Macaron-V1, a GLM-5.2-based model family built around continual learning and multi-LoRA collaboration.

The flagship Venti variant combines a frozen 744B GLM-5.2 base with four 1B LoRA experts for chat, agent work, coding, and generative UI.
MindLab argues that post-training should not end when parameters freeze: the model should keep learning from deployment-time experience.
Its Mixture-of-LoRA design treats LoRA adapters as persistent, writable local state rather than just cheap fine-tuning patches.
The article cites scaling results showing LoRA RL can be cheaper than full-parameter RL while still improving performance on large MoE models.
On the systems side, MindLab pairs the model with MinT, MindForge, HCP, and LongStraw to align training, serving, long-context RL, and agent harnesses.
The release also includes open weights for Macaron-V1-Venti, Macaron-V1-Coding-Venti, and Macaron-V1-Tall on Hugging Face.
