Scenic-Foundation/Scenic

A compiler and scenario generator for the Scenic scenario description language.

What it solves

Scenic addresses the difficulty of creating diverse and realistic test environments for cyber-physical systems (CPS). Instead of manually designing every single test case, it allows developers to describe the general properties of a scene—such as the layout of a possible road or the same relative same position of objects—// a probabilistic programming language that can generate a wide variety of valid scenarios based on those descriptions.

How it works

It functions as a compiler and scenario generator. Users write programs in a domain-specific probabilistic programming language (Scenic) to model environments. The tool then compiles these descriptions into concrete instances of scenarios that can be used in various simulators.

Who it’s for

It is designed for researchers and engineers working with cyber-physical systems, specifically those who need to generate large sets of realistic, randomized test environments for simulation and validation.

Highlights

  • Probabilistic programming approach to environment modeling.
  • Compiler-based architecture for scenario generation.
  • Interfaces with various simulators to create test environments.
  • Based on academic research from UC Berkeley and UC Santa Cruz.

    veyliss/ai-localbase

    AI LocalBase is a self‑hosted RAG platform built with Go (Gin), React, and Qdrant. It lets you upload local documents (txt, md, pdf, xlsx, csv), automatically embed them, store vectors in Qdrant, and perform retrieval‑augmented chat using Ollama or any OpenAI‑compatible model. Features include knowledge‑base management, chat history in SQLite, configurable hybrid/semantic search, and an built‑in MCP server for external agents. Deploy with a single Docker‑Compose command, optionally enable authentication, and run entirely on‑premise.
