Gambit is an open-source framework designed for developers to create reliable workflows using large language models (LLMs). It allows users to build workflows by composing small, typed components called "decks," each with defined inputs, outputs, and guardrails. This structure enhances reliability, making it easier to debug and test workflows. To use Gambit, you need Node.js 18 or higher and an OpenRouter API key. The framework can be run directly using npx, which eliminates the need for a manual installation. Users can quickly scaffold a new project with the command `npx @bolt-foundry/gambit init my-project`, generating a structured skeleton that includes directories for decks, actions, graders, and tests. Running examples can be done in the terminal or through a browser, with commands like `npx @bolt-foundry/gambit serve <deck>` starting a local server to interact with the decks. The CLI also provides functionalities for testing and grading sessions, allowing for a streamlined development experience. Key features of Gambit include local execution of decks, real-time debugging through a built-in UI, and the ability to handle both LLM and compute tasks seamlessly. The framework emphasizes small, manageable components, which helps avoid common issues like high costs from bulky context delivery and difficulties in orchestration. For developers looking for TypeScript integration, Gambit supports custom compute steps and validation through Zod. Overall, Gambit offers a robust toolkit for building and managing LLM workflows efficiently.
