This repository is a comprehensively governed, production-grade library of 115+ prompt templates, meta-prompt generators, workshop guides, and structured routines for AI-assisted product management. It is not a deployed software application but rather a content methodology repository with application-like engineering discipline: standalone prompt contracts, coupling levels, CI-validated metadata, deterministic catalog generation, and an explicit coupling remediation plan. The library covers the full product management lifecycle—discovery, strategy, requirements, competitive intelligence, end-of-life, storytelling, and team facilitation—using three defined interaction modes (facilitation, co-construction, autonomous investigation). Notable sub-collections include an eight-discipline market intelligence framework (OSINT, FININT, GEOINT, etc.) with an all-source fusion prompt, a complete product sunset (EOL) workflow, and a TAM-SAM-SOM market sizing Langflow pipeline. The repo exhibits hybrid character: while primarily a content asset, it includes reusable Python scripts for validation and catalog generation, a GitHub Actions CI pipeline, and follows software engineering best practices such as versioning, changelogs, and architectural decision records.
This repository is a curated, multi-vendor collection of leaked system prompts from major AI chatbots (ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, etc.), captured verbatim from production systems. It serves as a reference corpus for studying AI behavior instructions, safety guardrails, tool definitions, and product positioning across model versions and vendors. The repository also includes Claude Code bundled skills (code review, design-sync, dataviz, deep research) and Claude Design starter components, which are supplementary tooling. While primarily a documentation archive, it contains some well-crafted reusable components such as color palette validation scripts, a design system build/diff pipeline, and a deep research workflow script. The prompts are organized by vendor with version tracking, and the repository is actively maintained with recent updates. However, the tooling scripts lack dependency pinning, and the prompts are time-sensitive snapshots that will drift as products evolve.
This repository is a structured, comprehensive AI engineering curriculum spanning 20 phases and over 500 lessons, from math foundations and ML fundamentals to deep learning, computer vision, NLP, speech, transformers, generative AI, reinforcement learning, LLMs from scratch, agent engineering, multi-agent systems, production infrastructure, and ethics/safety. It is an educational resource, not a production application or data research project. The code consists of self-contained pedagogical implementations (primarily Python, with some TypeScript, Rust, and Julia) that demonstrate core algorithms from scratch—such as attention mechanisms, BPE tokenization, diffusion models, RLHF, and agent loops—using synthetic data and deterministic stubs. Capstone projects include small web servers (Hono/TypeScript) and test harnesses. The curriculum is actively maintained with CI tooling, certification prep materials, and translation support. While the code is simplified for learning, it exhibits clean patterns, consistent lesson structure, and testing practices that make individual components (e.g., tool registries, state machines, evaluation harnesses) reusable in other contexts.
ChatTTS is a generative speech model application designed specifically for dialogue scenarios, functioning as a Text-to-Speech (TTS) library with integrated serving infrastructure. The core logic resides in the ChatTTS package, where `ChatTTS/core.py` defines the main inference interface. The architecture combines a GPT-based language model (`ChatTTS/model/gpt.py`) for token generation, a DVAE (`ChatTTS/model/dvae.py`) for audio compression, and Vocos as a vocoder. The system supports multiple speakers, prosodic control (laughter, pauses), and text normalization for Chinese and English. Deployment is handled through multiple entry points: a FastAPI-based API server (`examples/api/main.py`), a Gradio WebUI (`examples/web/webui.py`), and CLI tools (`examples/cmd/run.py`). A significant engineering highlight is the integration of vLLM (`ChatTTS/model/velocity/`) to optimize inference throughput for the GPT component. The repository includes robust asset management (`ChatTTS/utils/dl.py`) for model weights with SHA256 verification and ONNX export capabilities (`examples/onnx/exporter.py`) for cross-platform deployment. While the underlying model is research-grade (trained on 100k+ hours of audio), the repository structure prioritizes application delivery over experimental research. It provides a stable library interface with clear separation between model logic, audio processing (`tools/audio/`), and serving layers. The codebase demonstrates high craftsmanship in handling stochastic generation reproducibility (`tools/seeder/ctx.py`) and speaker embedding management (`ChatTTS/model/speaker.py`), making it a production-ready TTS solution rather than a raw research notebook collection.
HealthGPT is an iOS application that enables users to interact with their Apple Health data using large language models (LLMs) in a conversational interface. Built on the Stanford Spezi modular framework, the app supports three LLM execution modes: remote OpenAI (GPT-3.5/4), on-device local models (Llama3 via MLX), and privacy-preserving fog nodes within the local network. The architecture follows a monolith application pattern with clear separation of concerns: HealthDataFetcher queries HealthKit for steps, sleep, heart rate, etc.; HealthDataInterpreter prepares the LLM context with a system prompt generated from the fetched data; and the SwiftUI ChatView manages the conversation flow. External dependencies include Spezi modules (HealthKit, LLM, Onboarding, Storage) and OpenAI API. The codebase is well-structured with SwiftLint enforcement, comprehensive UI and unit tests, CI/CD pipelines via GitHub Actions and Fastlane, and an automated TestFlight deployment workflow. While the app is tightly coupled to the iOS ecosystem and Apple HealthKit, the data fetching, prompt generation, and LLM orchestration patterns are cleanly abstracted and potentially reusable in other health-related Swift applications.
VeritasGraph is a comprehensive, governed GraphRAG and agent framework for building enterprise-grade knowledge graphs with verifiable attribution. The repository contains a core Python library (VeritasReason) for knowledge graph construction, semantic extraction, reasoning, provenance tracking, and export, along with multiple domain-specific applications: a HIPAA-safe clinical knowledge graph pipeline (clinical-kg), a floorplan extraction and validation web app (floorplan-kg), a municipality incident reporting chatbot, and a Model Context Protocol (MCP) server for IDE integration. The architecture is modular, with a plugin-based method registry pattern, unified configuration management, and a pipeline orchestration engine. While the primary character is an application framework, it also includes research-oriented components such as clinical benchmarks (MedKG-Signal) and evaluation suites, making it a hybrid project with a strong application focus.
Image-Blaster is a generative 3D asset pipeline and web viewer that transforms a single input image into a fully interactive 3D scene. The system uses Claude AI agents to orchestrate a multi-step workflow: image analysis and object extraction, background removal (plate generation), world generation via World Labs (gaussian splats, colliders, panoramas), 3D object generation via FAL (Hunyuan3D or Meshy), and sound effect generation via ElevenLabs. All generated assets are stored locally with a deterministic indexed naming convention and request metadata for resumability. The frontend is a React 19 + Three.js (R3F) application with physics (Rapier), post-processing (Bloom, DoF, motion blur), splat rendering (SparkJS), and a full scene editor with undo/redo, transform controls, and asset library. The architecture is a monorepo with a Vite dev server that serves assets and provides a CRUD API for scene projects. While the system is primarily an application, it also contains a data pipeline aspect in its asset generation scripts, which follow a consistent lifecycle of submission, polling, download, and metadata writing. The codebase demonstrates strong engineering practices with reusable patterns like the FAL queue wrapper, indexed file resolution, camera gesture hooks, and error boundaries. However, it is heavily dependent on external cloud APIs (FAL, World Labs, ElevenLabs) and Claude agent tooling, with no offline fallback or mock mode.
This repository implements a fully autonomous pipeline that generates, produces, and uploads educational YouTube videos daily. It uses the Gemini 2.5 Flash API to create lesson scripts and curricula, gTTS for narration, Pexels for background imagery, and MoviePy/Pillow for video rendering. The pipeline runs on a GitHub Actions cron schedule, requiring no manual intervention. It produces both a long-form lesson video and a YouTube Short, uploads them with custom thumbnails, and updates the content plan repository. The code is well-structured for its purpose, with proper error handling, retry logic for TTS rate limits, and credential management for YouTube OAuth. While not a reusable library, it demonstrates good software engineering practices for a CI/CD-based content generation system.
This repository implements an end-to-end 3D object generation application that takes natural language descriptions and produces 3D mesh models (GLB format). It orchestrates three generative AI models: an LLM (Qwen3 or Llama) for scene planning, a diffusion model (SANA Sprint) for 2D image generation, and Microsoft TRELLIS for 3D generation. The system presents a Gradio web interface for user interaction and includes a Blender addon for direct import of generated assets. It supports two deployment modes: native PyTorch models (for local development) and NIM containers (for scalable inference). Key architectural patterns include a singleton GPU memory manager that coordinates model loading/unloading across VRAM-constrained GPUs, a guardrail service for content safety, and a conditional service abstraction that transparently switches between native and NIM backends based on configuration. The repository is well-structured with modular UI components and comprehensive installation scripts, though it is Windows-only and has complex event chains in the main UI file. The code is actively maintained with recent commits and pinned dependencies, but the heavy reliance on patched versions of TRELLIS and a specific Gradio version introduces some maintenance risk.
This repository is a large curated dataset rather than a software application or data pipeline. It contains a multilingual, awesome-list style directory of 3,527 generative AI applications organized into 80 categories, with README.md as the canonical content store. Each entry follows a reproducible markdown record schema: application name, screenshot URL, short description, visit redirect link, and a separate pricing/information link. Categories span the generative AI ecosystem, including AI agents, chatbots, image/video generation, code assistants, legal, accounting, and gaming. The data_research classification reflects the fact that the primary asset is structured content, not executable code; there are no notebooks, model files, or ETL scripts in the repository.
This repository implements the Agent-to-Agent (A2A) protocol in Python. It is a comprehensive SDK providing both server and client libraries for building interoperable agent systems. The architecture is modular with abstract interfaces (AgentExecutor, TaskStore, ClientTransport) and supports multiple transports: JSON‑RPC, REST/HTTP+JSON, and gRPC, with a full backward‑compatibility layer for v0.3. Key features include agent card signing/verification (JCS canonicalization), push notifications, event streaming, and database persistence via SQLAlchemy. The codebase is well-structured with extensive automated testing (unit, integration, cross‑version, and conformance), CI/CD pipelines, and release automation. While primarily an SDK for protocol compliance, it also includes a sample agent application and an interop test kit.
WorldGen is a Python library and demo application for generating 3D scenes from text prompts or single images in seconds. It orchestrates a pipeline of state-of-the-art models: a fine-tuned FLUX diffusion model to generate 360° panoramic images, DA-2 for monocular depth estimation on equirectangular images, and optionally OneFormer for semantic segmentation and LaMa for inpainting to handle background occlusions. The 3D scene is produced as a Gaussian splatting point cloud (via a custom RGBD-to-Gaussian conversion) or as a textured mesh. An experimental mode uses Apple's Sharp model for higher-quality Gaussian splats by processing cubemap faces. The codebase demonstrates strong engineering practices for a research project: modular pipeline design, use of submodules for dependencies, custom diffusers pipelines with VAE tiling modifications for seamless panorama generation, and a Viser-based interactive viewer. While the core value is the integrated pipeline, several utility modules (equirectangular projection utilities, splat file handling) are cleanly isolated and reusable in other 360° or 3D vision projects.
This repository is a full-stack marketing demo application powered by Google Cloud generative AI (Vertex AI Gemini, Imagen). It provides an end-to-end workflow for generating campaign content (emails, social media posts, website copy, images), analyzing audiences via natural language to BigQuery, and managing assets across platforms. The frontend is a modern Angular 17 single-page application with Firebase authentication and hosting, while the backend is a FastAPI Python service deployed on Cloud Run. Terraform infrastructure-as-code provisions all GCP resources including BigQuery datasets, Vertex AI Search datastores, Dialogflow CX agents, and Google Drive folder templates for content export. The application showcases marketing use cases like trendspotting via GDELT news summarization, audience insights using structured and unstructured data, and interactive image editing with inpainting/outpainting. While primarily a demo application, the repository also contains several Jupyter notebooks exploring model tuning, text-to-SQL, and clustering explanations, making it a hybrid resource for both application developers and data scientists.
This repository is the official implementation of the SANA family of diffusion models for high-resolution image and video generation, developed by NVIDIA Research. It is primarily a research codebase, containing training and inference pipelines for multiple model variants: SANA (text-to-image), SANA-1.5, SANA-Sprint (few-step distillation), SANA-Video, SANA-Video 2.0, SANA-Streaming (long video), LongSANA, and SANA-WM (world model for camera-controlled video). The codebase also includes post-training with reinforcement learning (Sol-RL), ControlNet support, and various schedulers (flow matching, DPM-Solver, LCM, self-forcing). While the core purpose is research, the repository also provides deployable Gradio applications, conversion scripts to Hugging Face diffusers format, and integration with ComfyUI and SGLang, giving it a hybrid application character. The code is heavily optimized with custom Triton kernels for efficient attention (LiteMLA, Gated Delta Net) and includes distributed training utilities (FSDP, context parallelism). The repository is actively maintained with frequent commits and supports a wide range of model sizes (600M to 14B parameters).
This repository is a ComfyUI custom node pack that extends the standard ControlNet functionality with advanced scheduling, weighting, and masking capabilities. It provides nodes for timestep and latent keyframes, custom weight curves, attention masks, effect masks, and sliding context windows for video generation (AnimateDiff integration). The system supports multiple control types: ControlNet, T2IAdapter, ControlLoRA, ControlLLLite, SparseCtrl, SVD-ControlNet, Reference, ControlNet++, and CtrLoRA. It also replicates features from Auto1111 like 'My prompt is more important' via soft weights and uncond_multiplier. The architecture is modular, with separate files for each control family (control.py, control_reference.py, control_ctrlora.py, etc.), a shared utilities module (utils.py) providing base classes like AdvancedControlBase and ControlWeights, and a node registration layer (nodes.py, nodes_main.py, etc.). The system integrates deeply with ComfyUI's internal APIs (comfy.controlnet, comfy.model_patcher, comfy.hooks) and uses monkey-patching to inject advanced behavior into standard control objects. A custom inter-node communication protocol (DinkLink) enables coordination with AnimateDiff-Evolved. Key entry points are the node classes registered in __init__.py and nodes.py, which are loaded by ComfyUI's extension system. The primary data flow involves loading a control model, optionally converting it to an advanced version, applying timestep/latent keyframes and weights, and then applying the control during sampling with optional reference injection or sliding context. The system is actively maintained with recent commits, CI publishing, and example workflows demonstrating advanced features like Qwen Image Inpainting and Anima LLLite v2.
This repository is a comprehensive, educational collection of 42+ Jupyter notebooks and runnable scripts demonstrating a wide array of Retrieval-Augmented Generation (RAG) techniques. It is primarily a data_research and educational resource, not a deployable application or library. The codebase serves as a practical cookbook for engineers and researchers, covering the full RAG stack from basic chunking and retrieval (e.g., simple RAG, BM25) to advanced methods like GraphRAG, Self-RAG, HyDE, RAPTOR, and agentic RAG. It also includes a dedicated evaluation framework with notebooks and reusable scripts for measuring faithfulness, relevance, and correctness using tools like DeepEval and custom LLM judges. The architecture is modular, with a shared helper_functions.py providing common utilities for PDF loading, embedding, and retrieval, and an evaluation/ module offering reusable evaluation pipelines. The runnable scripts in all_rag_techniques_runnable_scripts/ provide cleaner, class-based implementations of the techniques that are more suitable for integration into other projects than the notebooks themselves. While the code is well-structured for an educational project and demonstrates high craftsmanship in its reusable components, it is not designed for production deployment. Reproducibility is limited by the lack of a pinned dependency file and reliance on external API keys. The repository is actively maintained and highly influential (29k+ stars), making it a valuable reference for anyone building or evaluating RAG systems.
The Prompt Engineering Guide is a comprehensive, multilingual documentation site built with Next.js and Nextra that serves as an educational resource for prompt engineering with large language models. While the site itself is a web application, its core value lies in the extensive collection of tutorials, technique explanations, model-specific guides, and research summaries that constitute a structured knowledge base on effective LLM prompting. The repository includes interactive Jupyter notebooks that demonstrate practical applications of techniques like PAL, RAG, and ReAct, alongside hundreds of MDX pages covering topics from basic prompting to advanced agent building. Content is available in numerous languages, reflecting a commitment to global accessibility. The site features custom UI components for enhanced usability, such as announcement bars, course promotions, and copy-to-clipboard functionality, but these serve primarily to facilitate access to the educational content. Despite being actively maintained, the guide faces challenges typical of rapidly evolving fields: content requires frequent updates to keep pace with new LLM releases and research findings, and the multilingual nature increases the risk of translation drift. External links to papers, videos, and tools may also become stale over time. Nevertheless, the repository remains a valuable reference for practitioners and researchers seeking to understand and apply prompt engineering principles.
HunyuanVideo-1.5 is an open-source video generation model by Tencent, implemented as a Python library with CLI scripts for inference (`generate.py`) and training (`train.py`). It generates high-quality videos from text or image prompts using a diffusion transformer (DiT) architecture with 8.3B parameters, supporting resolutions up to 1080p via super-resolution. The codebase provides a modular pipeline (`HunyuanVideo_1_5_Pipeline`) that orchestrates prompt encoding (byT5 text encoder, SigLIP vision encoder), denoising with flow matching, and VAE decoding. It includes advanced features like SSTA (Selective and Sliding Tile Attention) for efficient long-video processing, step distillation, CFG distillation, and various caching mechanisms (DeepCache, TeaCache, TaylorCache). The repository also offers a training script with distributed support (FSDP, context parallelism), LoRA fine-tuning, and the Muon optimizer. While primarily an application for video generation, it contains research-grade model implementations and evaluation benchmarks. The code is well-structured with reusable neural network modules, but relies on many optional hardware-specific dependencies (flash-attn, flex-block-attn, SageAttention) and external services for prompt rewriting, which may introduce operational complexity. The license is a custom Tencent Hunyuan Community License with restrictions.
Eidolon is an open-source framework for building, deploying, and managing multi-agent AI applications. It provides a Python SDK with abstractions for LLM integration (OpenAI, Anthropic, Mistral, Ollama, Azure), retrieval-augmented generation (RAG) pipelines, memory systems (vector stores, symbolic memory, file storage), and document processing (loaders, parsers, splitters). Agents are configured declaratively via YAML and can communicate with each other, use tools, and stream responses. The framework includes a Kubernetes operator for production deployment, a web UI built with Next.js and React for chatbot interaction and developer tooling, and a TypeScript client library. It also features built-in agent types like SimpleAgent, RetrieverAgent, SQLAgent, and a Tree-of-Thought agent, along with logic units for web search, browser automation, and API integration.
This repository implements a Chinese-localized version of the Stanford Generative Agents simulation. It creates a virtual town with 25 AI agents powered by LLMs (primarily via Ollama) that autonomously organize events, form relationships, and exhibit human-like behaviors. The system consists of a simulation engine that runs agent interactions over time, a compression tool to generate replay data, and a Flask-based web frontend for visualizing the simulation. Agents maintain memory, generate plans, reflect on experiences, and interact through LLM-driven conversations and actions. The application supports local deployment with configurable LLMs and includes features like breakpoint resumption and conversation logging.
