NumPy is a Python library providing a multidimensional array object and routines for fast operations on arrays, including mathematical, logical, sorting, Fourier transforms, linear algebra and random simulation. It is open source under a BSD license and is described as the fundamental package for scientific computing in Python, with core code written in optimized C.
MinerU is a tool that transforms complex documents such as PDFs and Office documents into LLM-ready markdown or JSON for agentic workflows. It supports multiple input formats including PDF, images, DOC/DOCX, PPT/PPTX, XLS/XLSX, RTF, ODT/ODS/ODP, EPUB, OFD, HTML/MHTML and CSV/TSV. Version 4.0 offers four parsing tiers and a document library with search and citation locators, and documents are not automatically uploaded to the official service; remote parsing requires explicit configuration.
Orkas is an open-source, local-first AI desktop app. A commander LLM directs specialist sub-agents and runs installed coding CLIs including Claude Code, Codex, OpenCode, OpenClaw, and Hermes as local sessions. Its agents self-evolve via reflection and skill crystallization, supports bring-your-own keys, and is compatible with macOS, Windows, and Linux.
ParaMonte is a serial and parallel library of Monte Carlo routines for sampling mathematical density functions of arbitrary dimensions and machine learning algorithms for scientific inference. It is designed for interoperability with C, C++, Fortran, MATLAB and Python, and supports shared-memory OpenMP threads and MPI distributed communications.
Plotly's Python graphing library is a free, open-source library for building interactive, publication-quality charts and graphs. It supports chart types including line plots, scatter plots, bar charts, error bars, box plots, histograms, heatmaps, subplots, multiple-axes, polar charts, and bubble charts. The source is available on GitHub.
PyQtGraph is a pure-Python graphics library that uses the Qt framework. It is intended for mathematics, scientific and engineering applications, and relies on numpy for number crunching, Qt's GraphicsView for 2D display and OpenGL for 3D display. It supports Python 3.12+, Qt 5.15 or 6.8+, and numpy 2.2+.
regression-js is a JavaScript library for curve fitting. It is hosted on GitHub and can be contributed to by the community. It is open source and available for installation via npm.

Ruffus is an open-source computation pipeline library for Python, used in science and bioinformatics. It is designed to automate scientific and other analyses with a lightweight, standard-Python syntax, and can be installed from the Python Package Index.
SVGo is a Go language library for SVG generation. It supports common SVG elements including shapes, lines, text, paths, images, and gradients, and is hosted as an open-source project on GitHub.
torchvista is an open-source tool that enables interactive visualization of PyTorch forward passes in Jupyter notebooks, maintained as a public GitHub repository under the sachinhosmani organization. It supports interactive drag-and-zoom graphs, collapsible nodes for hierarchical modules, and error-tolerant partial visualization when errors arise.
Vaex is an open-source Python DataFrame library for working with large tabular datasets without loading them fully into memory. It supports lazy opening of CSV files and processing of hundreds of millions or billions of rows per second. The project also offers consultancy and training services.
BELLE, short for Be Everyone's Large Language model Engine, is an open-source Chinese conversational large language model hosted on GitHub by LianjiaTech. The project provides relevant training code and open datasets for the model.
Chatbox is a desktop client for ChatGPT, Claude and other LLMs, available for Windows, Mac and Linux. It supports multiple LLM providers including OpenAI, Azure OpenAI, Claude, Google Gemini Pro, Ollama and ChatGLM-6B, and stores data locally. This repository covers the Community Edition, open-sourced under GPLv3.
LAION, the Large-scale Artificial Intelligence Open Network, is a non-profit organization that provides datasets, tools and models to support open machine learning research. Its offerings include the LAION-400M dataset of 400 million English image-text pairs, LAION-5B of 5.85 billion multilingual CLIP-filtered pairs, and the CLIP H/14 vision transformer model.
Metaflow is an open-source framework for building and managing ML, AI, and data science projects. It supports using Python libraries, orchestration workflows in Python, versioning, and scaling compute to the cloud, including GPUs. It was originally developed at Netflix and open-sourced in 2019.
Model-agnostic SDK for building, orchestrating and deploying AI agents and multi-agent systems, with built-in support for OpenAI, Azure OpenAI, Hugging Face and Nvidia. It offers tools/plugins, memory, planning, vector database integrations and a process framework. Microsoft states that Semantic Kernel is now Microsoft Agent Framework.
