Deep-Live-Cam is a real-time face swapping desktop application that uses ONNX Runtime with insightface models to swap faces in live webcam feeds or pre-recorded images/videos. The core pipeline involves face detection (RetinaFace), face recognition (ArcFace), and a face swap model (inswapper_128), with optional face enhancement via GFPGAN or GPEN-BFR ONNX models. The application provides a PySide6 GUI for selecting source/target faces, toggling options (mouth mask, many faces, Poisson blending, sharpening, temporal interpolation), and managing camera selection. It supports multiple execution providers: CUDA (NVIDIA), CoreML (Apple Silicon), DirectML (AMD/Intel), OpenVINO (Intel), and CPU fallback. Video processing can run in-memory via FFmpeg pipes (avoiding disk I/O) or via traditional frame extraction to PNG files. The architecture is modular: frame processors (face swapper, enhancers) follow a common interface, and the codebase includes optimizations for Apple Silicon (CoreML subgraph optimization, Pad decomposition, Shape/Gather folding) and CUDA (IO binding, CUDA graphs). The project also includes a benchmark pipeline and unit tests for core components.
This repository is a PyTorch Lightning implementation of DeepMind's Skillful Nowcasting GAN (DGMR) for precipitation nowcasting. It provides a modular, well-structured library of neural network components including residual blocks (GBlock, DBlock, LBlock), conditioning stacks (ContextConditioningStack, LatentConditioningStack), a ConvGRU-based sampler, spatial and temporal discriminators, and multiple loss functions (hinge, grid cell, SSIM, etc.). The core model (DGMR) wraps these components into a PyTorch Lightning module with manual optimization for the GAN training loop. It supports HuggingFace Hub integration for pretrained weights and includes training scripts for the UK Nimrod radar dataset. The codebase is well-documented, type-annotated, and includes comprehensive unit tests for individual components, making it suitable both as a library for nowcasting research and as a reference implementation for complex GAN architectures.
Pollinations is a large monorepo hosting a multi-modal generative AI platform. It provides a unified API gateway (gen.pollinations.ai) for text, image, video, audio, 3D, and embeddings generation, routing requests to dozens of providers (OpenAI, Anthropic, Google, Fal, Replicate, ElevenLabs, etc.) with fallback chains, caching, rate limiting, and billing. A separate enterprise service (enter.pollinations.ai) handles authentication (GitHub OAuth, API keys, device code flow), user dashboards, API key management, Stripe/Pollen billing, community-hosted model endpoints, and a quest/reward gamification system. The platform also includes a design system UI library (@pollinations/ui), a Node.js SDK, a CLI tool (polli-cli), an MCP server, and over 20 community apps (chat, AI dungeon master, image reimagine, Discord bots, etc.). Infrastructure includes Cloudflare Workers, Durable Objects, D1, R2, Tinybird for analytics, and GPU inference servers (Flux, Dreamshaper, Z-Image) deployed on Vast/IO.net. The architecture is service-oriented within a monorepo: each major service (gen, enter, media, pollinations.ai) is a separate Cloudflare Worker with its own wrangler.toml and dependencies. Shared packages (shared/, packages/) provide cross-cutting concerns like billing logic, model registry, auth middleware, HTTP error handling, and UI components. Data flows from user requests through middleware (auth, balance, cache, rate-limit, safety, model resolution) to provider-specific adapters, with usage events published to Tinybird for analytics and billing. The system is heavily tested with Vitest, including integration tests with Cloudflare Workers test environment and VCR snapshots. External dependencies include Cloudflare (Workers, D1, R2, KV, Durable Objects, Vectorize), Tinybird (analytics), Stripe (payments), GitHub (OAuth, quests), and numerous AI model providers. The codebase is predominantly TypeScript with some Python (Floret agent, GPU servers, social automation) and Rust (polli-core for Discord bot). While the core platform is well-maintained, there is significant drift in community apps and infrastructure scripts, and the sheer number of provider integrations creates maintenance surface area.
This repository is a comprehensive collection of annotated PyTorch implementations of deep learning papers, spanning transformers, GANs, reinforcement learning, diffusion models, and more. Each implementation includes side-by-side notes explaining the code and underlying concepts, making it an educational resource for understanding and reproducing paper results. The codebase is organized by paper/model type, with standalone experiment scripts, reusable modules, and configuration-driven training loops. Key strengths include clean abstractions for transformer components, a flexible configs system, and extensive coverage of both foundational and modern architectures. However, the project has not seen commits since early 2024, some dependencies are outdated, and certain experiments require large GPU resources or external data not bundled in the repo. While individual components are well-crafted and reusable, the overall collection is best used as a reference and learning tool rather than a production framework.
The SmartNoise SQL/Synth/Eval monorepo is a differentially private (DP) data analysis toolkit. It provides three main packages: `snsql` (DP SQL query rewriting with calibrated noise), `snsynth` (DP synthetic data generation via MWEM, GANs, MST, and other mechanisms), and `sneval` (evaluation of synthetic data quality). The SQL package includes a custom ANTLR-based SQL parser (`SqlSmall.g4`) that rewrites queries to enforce DP, supports multiple backends (Pandas, Spark, PostgreSQL, SQL Server, BigQuery), and tracks privacy budgets via an odometer. The synth package offers a rich set of synthesizers (DPCTGAN, PATECTGAN, MWEM, MST, AIM, etc.) with a consistent `fit`/`sample` API and a `TableTransformer` pipeline for preprocessing. The eval package provides metrics for comparing real vs. synthetic data, including accuracy, bias, and suppression/fabrication counts. The repository includes extensive tests (SQL parsing, mechanism accuracy, synthesizer round-trips) and sample notebooks demonstrating DP workflows.
This is a Python application and library for singing voice conversion and real-time voice changing, forked from so-vits-svc and rebuilt around PyTorch, PyTorch Lightning, and a Click-based CLI. The actual code provides two user-facing entry points: the `svc` CLI with commands for inference, realtime microphone conversion, dataset preprocessing, training, clustering, and cleanup, and the `svcg` PySimpleGUI desktop application for interactive and realtime inference. Inference loads a HuBERT content encoder from Hugging Face, extracts pitch using CREPE, DIO, Harvest, or Parselmouth, then runs a VITS-style SynthesizerTrn with either HiFi-GAN or MS/MB-iSTFT decoders conditioned on speaker embeddings. Despite fastapi being listed as a dependency, no HTTP API server exists in the source; the project is a desktop/CLI tool, not a web service.
This repository is a curated 'awesome list' (bibliography) of research papers, datasets, and software tools at the intersection of artificial intelligence and molecular dynamics/conformational analysis. It contains no executable code, data files, or notebooks—only a single README.md that organizes hundreds of references by topic (e.g., neural network potentials, force fields, generative models for protein conformations, AlphaFold-based methods). The repo serves as a comprehensive literature index for researchers in computational chemistry and structural biology, but it is not a functional software project or data pipeline. No raw data, transformation scripts, or analytical models are present; reproducibility is not applicable.
