Mind Lab Toolkit (MinT)

An organized, click-through training process. Compute scheduling, distributed rollout, and training orchestration are handled for you, so launching a run takes just a few clicks. Builders and researchers stay in control of model selection, data preparation, and evaluation while MinT manages the rest.

AutoResearch: models that improve from usage. MinT keeps a shared base model resident and trains only lightweight LoRA adapters on top of it, so every evolution is cheap and instantly swappable. The AutoResearch loop runs automatically: production usage → training → publishing. Each evolution produces only a candidate version, promoted after passing evaluation, rolled back with one click if it regresses. The model learns from its own usage, so the more it's used, the stronger it gets.

MinT reduces engineering friction further by standardizing logging, providing portable workflows, and ensuring interpretable training data lineage. The unified platform supports both mainstream and frontier-scale models, including the Qwen3 series.

Key features and benefits:

• LoRA (Low-Rank Adaptation) RL - train large models with far less GPU cost than full-parameter fine-tuning, with comparable performance.
• Unified, reproducible RL infrastructure supporting multiple models and tasks.
• Abstraction of infrastructure complexity: GPU cluster management, distributed training, and model state handling.
• Robust training pipelines centered on RLHF/GRPO and general policy optimization.
• Scalable experience capture across diverse task distributions, longer horizons, and richer environmental constraints.
• Frictionless migration with initial API compatibility for ThinkingMachines Tinker.
• Distributed data collection, rolling training, weight management, and model publishing.
• Online evaluation on standard CPU clusters for continuous performance monitoring.
• Core API for gradient computation, parameter updates, generation, and state persistence.

Whether you are an RL researcher standardizing workflows or a team building agentic systems at scale, Mind Lab Toolkit accelerates RL research and deployment, reduces operational overhead, and delivers reproducible, cost-efficient training.
