Lexsi Labs unveils Orion-MSP: new AI model for enterprise structured data

On November 12, 2025, Lexsi Labs, a research division of Aurionpro Solutions, announced the launch of Orion-MSP, a new state-of-the-art Tabular Foundation Model. This model aims to deliver enterprise-grade accuracy and scalable deployment for any tabular predictive task. Concurrently, Lexsi Labs released TabTune, an open-source library designed to standardize fine-tuning and inferencing for leading tabular foundation models, including Orion-MSP.

Orion-MSP employs multi-scale processing, block-sparse row-wise attention, and Perceiver-style latent memory for efficient modeling of wide, heterogeneous tables with reduced computational complexity. Early results demonstrate competitive performance on large feature sets and real-world datasets, surpassing current Tabular Foundation Models on several global benchmarks. TabTune offers data science teams a single, easy-to-use tool for adapting, evaluating, and deploying powerful tabular foundational models.

Lexsi Labs, formerly AryaXAI Alignment Labs, integrates alignment theory, interpretability science, and agentic autonomy into its research. The company operates in Mumbai, Paris, and London, focusing on advancing safe, interpretable AI that aligns with human values. Orion-MSP is available on Hugging Face, with full research details published on arXiv, while TabTune is accessible on GitHub.
