About
LongCat-2.0 is a 1.6 trillion total-parameter Mixture-of-Experts language model built on AI ASIC superpods, with about 48 billion parameters activated per token and strong performance across coding and agentic tasks. It is a substantial step up from previous LongCat models, combining large-scale sparse architecture with dedicated post-training for real-world software engineering, tool use, long-context reasoning, and multi-step agent workflows. LongCat-2.0 is trained and deployed entirely on AI ASIC superpods, with pretraining spanning more than 35 trillion tokens and millions of accelerator-hours, demonstrating frontier-scale training on alternative hardware platforms. To strengthen long-horizon tasks, the model introduces LongCat Sparse Attention and is trained on hundreds of billions of tokens of 1M-context data, giving it native support for ultra-long context tasks and reliable long-document understanding.

About
PageIndex is a human-like document AI platform for understanding long, complex documents with precise, verifiable answers grounded directly in the source. It uses vectorless, reasoning-based retrieval instead of embeddings, chunking, or vector databases, transforming each document into a tree-structured index that mirrors how people navigate sections, subsections, pages, and content. An LLM then reasons over that structure to decide where to look for relevant information, producing context-aware retrieval that is traceable and explainable. Users can upload reports, filings, research papers, technical manuals, legal documents, medical files, textbooks, and business plans, then ask questions with line-level citations that can be reviewed and verified. PageIndex supports ultra-long documents spanning thousands of pages and understands text, tables, charts, figures, and images.
