MiniMax-01: Scaling Foundation Models with Lightning Attention

We introduce MiniMax-01 series, including MiniMax-Text-01 and MiniMax-VL-01, which are comparable to top-tier models while offering superior capabilities in processing longer contexts. The core lies in lightning attention and its efficient scaling. To maximize computational capacity, we integrate it with Mixture of Experts (MoE), creating a model with 32 experts and 456 billion total parameters, of which 45.9 billion are activated for each token. We develop an optimized parallel strategy and highly efficient computation-communication overlap techniques for MoE and lightning attention. This approach enables us to conduct efficient training and inference on models with hundreds of billions of parameters across contexts spanning millions of tokens. The context window of MiniMax-Text-01 can reach up to 1 million tokens during training and extrapolate to 4 million tokens during inference at an affordable cost. Our vision-language model, MiniMax-VL-01 is built through continued training with 512 billion vision-language tokens. Experiments on both standard and in-house benchmarks show that our models match the performance of state-of-the-art models like GPT-4o and Claude-3.5-Sonnet while offering 20-32 times longer context window. We publicly release MiniMax-01 at https://github.com/MiniMax-AI.

STAG-VIO: Stabilized Prompt-to-Geometry Interface for Robust Dynamic Visual--Inertial Odometry

Dynamic visual-inertial odometry (VIO) requires reliable suppression of motion-corrupted measurements, yet prior semantic-assisted approaches depend on category-limited segmenters and degrade under partial occlusion. Promptable foundation segmentation models offer category-agnostic dynamic parsing, but their effectiveness in VIO depends critically on the temporal stability of input prompts---a factor largely overlooked in existing pipelines. When prompts derived from raw detection are jittery or intermittent under occlusion, the resulting masks flicker across frames, destabilizing geometric estimation. We propose STAG-VIO, which formulates dynamic robustness as a perception-to-geometry interface stabilization problem. We introduce uncertainty-adaptive multi-object tracking that models prompt generation as state estimation with bounded noise adaptation, producing temporally coherent box prompts. These stabilized prompts drive a lightweight foundation segmenter whose masks undergo geometry-oriented morphological refinement to establish conservative safety margins. A constraint-budget-aware feature redistribution strategy preserves well-conditioned static measurements when dynamic regions dominate the view. Experiments on VIODE and OpenLORIS-Scene show consistent gains over state-of-the-art baselines. Ablation confirms that prompt stabilization is the single most impactful component, reducing trajectory error by up to 83%.
