spaCy

What is spaCy?
spaCy is a Python library designed for practical, real-world Natural Language Processing (NLP) tasks. It provides fast and efficient processing of large text datasets, supporting over 75 languages with 84 trained pipelines. The library is built with Cython for optimized speed and memory management, making it suitable for production environments. The core of spaCy revolves around the Language class, which processes text into Doc objects containing tokens and annotations.
Its modular pipeline architecture allows users to add or customize components such as tokenization, part-of-speech tagging, dependency parsing, named entity recognition, text classification, and more. spaCy also supports integration with machine learning frameworks like PyTorch and TensorFlow, enabling custom model training and deployment. Recent updates include the spacy-llm package, which integrates Large Language Models (LLMs) into spaCy pipelines for tasks requiring advanced language understanding without needing training data. The library also offers a project system to manage end-to-end workflows from prototyping to production, including data transformation, training, and deployment steps.
spaCy emphasizes reproducible training with detailed configuration files that capture all training parameters, facilitating experiment tracking and reruns. It also provides built-in visualizers for syntax and entity recognition, and an extensive ecosystem of plugins and community resources. For users needing annotation tools, spaCy's creators offer Prodigy, a separate efficient machine teaching tool that accelerates data labeling and model iteration. Overall, spaCy balances performance, extensibility, and ease of use, making it a preferred choice for developers and data scientists working on NLP applications.
Stellaris AI

What is Stellaris AI?
Stellaris AI builds large language models marketed around native safety and human-like reasoning for real-world tasks. Its flagship SGPT line targets text and code generation, knowledge Q&A, logical reasoning, and analytics at a scale the company describes as hundreds of billions of parameters. The public site centers on a waitlist for SGPT-4.5 rather than a self-serve chat product you can open today.
Where many LLM labs bolt safety filters on after training, Stellaris AI frames safety as part of the model stack through strict source referencing and harm minimization in the architecture. It also highlights Real-time Context Learning (RCL) for adapting answers with live knowledge, a combination aimed at teams that want cited outputs instead of unchecked generation.
Researchers, enterprise AI teams, and early adopters join the SGPT-4.5 waitlist for first access. The company cites 10+ years of research and three core product pillars: Stellaris GPT, Native Safety, and RCL.
