What does Manifest do?
Manifest is an open-source tool that acts as a smart router for your AI agents. Instead of sending every request to an expensive, powerful language model, it analyzes each query you send and automatically routes it to the most cost-effective model capable of handling the task. It supports over 500 models from major providers like OpenAI, Anthropic, Google, and others, all managed through a single interface. This means a simple request for the weather might go to a free model, while a complex coding task gets sent to a more capable paid model.
The tool works by locally analyzing each prompt in under 2 milliseconds, checking for factors like prompt length and technical keywords to classify the query into a complexity tier. It then selects the cheapest model you have configured for that specific tier. Key features include support for multiple AI agents, the ability to add custom OpenAI-compatible providers, automatic fallbacks to backup models if the primary fails, and detailed spending tracking with budget alerts to prevent unexpected costs.
Manifest is ideal for developers and individuals running personal AI agents like Hermes or using frameworks like LangChain. It's a practical solution for anyone who wants to keep their AI-powered projects running smoothly without overspending on unnecessary compute power. You can use it to manage costs for chatbots, coding assistants, or any other application that relies on language model APIs.
