A Python library, built on Hugging Face Transformers, that trains and evaluates a range of NLP models in as little as three lines of code, covering classification, question answering, retrieval and generation tasks.

• Models
• Libraries

A visualization intermediate language that lets AI agents turn a compact, human-editable chart specification into a polished chart, compiling one input to Vega-Lite, ECharts, Chart.js, Plotly or native Excel output.

• Libraries

A fast, lightweight x86 and x86-64 disassembler and code generation library with no dynamic memory allocation and no third-party dependencies, used by projects such as x64dbg and Firefox.

• Debugging
• Libraries

A multi-language Vulkan, OpenGL, GLES, EGL, GLX, and WGL loader-generator based on the official specifications, with a web service that generates the loader files a project needs.

• Libraries

A C++ library for low-latency machine code generation, providing backend-independent core APIs plus x86, x64, and AArch64-specific assemblers and a higher-level compiler.

• Libraries

A form framework for React and Vue, designed for coding agents to reason about, with a single component API, co-located validation, and forms that automatically structure their own data.

• Libraries
• UI kits

A C++ framework, based on Google Chromium, for embedding a Chromium browser control inside other applications, used to render web content, build HTML-based UIs, or drive automated testing of web pages.

• Desktop
• Libraries

A JavaScript library, with ports in several other languages, that automatically inserts spacing between Chinese, Japanese or Korean text and adjacent Latin letters, numbers and symbols, plus a browser extension that applies it to web pages.

• Libraries

A Python library of extension and helper tools for everyday data-science and machine-learning tasks, including ensemble methods, feature selection and frequent pattern mining.

• Libraries

An open-source Python library of more than 500 financial analysis methods, written to be fully transparent about their calculations, with an optional MCP server for querying them without code.

• Libraries

A command-line PNG compressor that converts images to an efficient 8-bit palette format with alpha channel, typically shrinking files 60 to 80 percent, also available as an embeddable library.

• CLI tools
• Libraries

A concise but fully-featured PyTorch transformer implementation bundling many experimental architecture variants and training techniques from published papers.

• Models
• Libraries

A set of Java libraries implementing a parser and abstract syntax tree for Java 1.0 through Java 25, with an add-on symbol solver for resolving declarations and types.

• Code quality
• Libraries

A TypeScript wrapper around the TypeScript Compiler API that makes it easier to programmatically navigate and manipulate TypeScript and JavaScript source code.

• Code quality
• Libraries

A Python-embedded modeling language for convex optimization that lets a problem be expressed in natural mathematical form and solved with open-source solvers such as Clarabel, SCS, OSQP, and HiGHS.

• Libraries

An embedded operating system for Cortex-M and RISC-V microcontrollers that runs several mutually distrustful applications at once, isolating them with a Rust kernel and memory protection units.

• Libraries

An open-source Python library for offline machine translation, usable as a library, a command-line tool, or a GUI, with automatic pivoting through an intermediate language when no direct model is installed.

• Libraries

A research toolkit that compresses LLM prompts and key-value caches by removing non-essential tokens, reporting up to 20x compression with little quality loss.

• Inference
• Libraries

A Go library for building a customizable HTTP and HTTPS proxy server, supporting request and response manipulation, MITM certificate caching, and hijacked connections.

• Libraries
• Networking

A code generation and manipulation library that creates and changes Java classes at runtime without a compiler, usable as a library, a Java agent, or a build-time tool.

• Libraries

A C library implementing X.509 certificate handling and the TLS and DTLS protocols, with a small code footprint intended for embedded systems, plus a PSA Cryptography API implementation.
