How to Run a Mixed-Model AI Agent Team in TypeScript?
The article outlines a method for running a mixed-model AI agent team in TypeScript using the open-multi-agent framework, allowing different agents to use different models and providers for cost efficiency. It demonstrates how to configure agents with varying model tiers—such as Claude Opus, OpenAI, and a local Ollama model—to optimize performance and reduce expenses. The approach uses per-agent model assignment in AgentConfig, enabling flexible, production-ready setups with cost and latency monitoring.
- ▪The open-multi-agent framework supports per-agent model and provider configuration, avoiding global model lock-in.
- ▪Using mixed-model teams can significantly reduce costs by assigning only high-end models where necessary.
- ▪The framework supports multiple providers including Anthropic, OpenAI, Gemini, and local models via Ollama.
- ▪Examples in the repository demonstrate multi-model teams, cost-tiered execution, and integration with local or provider-specific models.
- ▪Cost tracking is enabled through an onProgress callback that provides per-agent token usage and dollar-cost estimates.
