Best open-source AI & Machine Learning projects

Persistent memory for AI coding agents that captures sessions automatically and injects relevant context into later sessions across Claude Code, Cursor, Codex and other MCP clients.

An open-source, community-contributed database of AI model specifications, pricing, and capabilities, served via a public API.

A CLI that detects your GPU, CPU and RAM and ranks the HuggingFace local LLMs that actually run on your hardware, by benchmarks rather than parameter count.

An open-source Go framework that organizes reusable AI prompts (called Patterns) by task and runs them from the command line or a REST API.

Compresses tool outputs, logs, files and RAG chunks before they reach an LLM, as a library, proxy or MCP server.

A pure instruction and knowledge kit that turns Claude and other coding agents into a UX/UI design expert, with DTCG tokens, component specs, 138 design systems and 52 objective gates.

A set of Claude Code skills that walk academic work through research, writing, peer review, revision and finalization, with a human approving each stage.

Engine-agnostic LLM gateway in Rust that routes OpenAI- and Anthropic-compatible traffic across self-hosted inference engines and cloud model providers.

A tavern-style role-play game agent built on DeepSeek Harness (DSH), compatible with SillyTavern character cards and assets.

Message your local coding agents like Claude Code and Codex as persistent bots from iPhone, Mac, Windows, Linux or a terminal.

A multi-agent swarm simulation engine that builds a digital world from seed material to predict outcomes of news, policy, or financial events.

Design guidance for AI coding agents, with a design skill, 24 commands, live browser iteration and 61 deterministic detector rules for AI-generated frontend UI.

A unified text-to-motion model that generates animations for arbitrary rigged skeletons, from humanoids to quadrupeds, birds, fish and insect-like rigs.

Anthropic-managed marketplace of curated, vetted plugins that extend Claude Code with commands, agents, skills and MCP servers.

A GitHub Action that runs Claude Code on PRs and issues to answer questions, review changes, and implement code.

A free, offline desktop app that scores and explains highlight moments in local video using scene, motion, audio, object and transcript signals.

Open-source tool that translates video into another language, with speech recognition, subtitle translation, AI dubbing and audio-video synthesis.

Seven AI personas modeled on public figures (Bezos, Paul Graham, Hormozi and others) debate a business decision inside Claude Code and return a scored verdict.

A DSH plugin that renders interactive UI components (charts, tables, forms, quizzes, plots, Mermaid) inline inside assistant replies.

Persistent memory for coding agents that captures session activity, compresses it with AI, and injects relevant context into future sessions.
