HMAS is an open-source Python framework that enables development of hierarchical multi-agent systems. It offers abstractions for defining agent hierarchies, inter-agent communication protocols, environment integration, and built-in training loops. Researchers and developers can use HMAS to prototype complex multi-agent interactions, train coordinated policies, and evaluate performance in simulated environments. Its modular design makes it easy to extend and customize agents, environments, and training strategies.

EspressoAI provides developers with a structured environment to design, configure, and deploy AI agents powered by large language models. It supports tool registration and invocation from within agent workflows, manages conversational context via built-in memory modules, and allows chaining of prompts for multi-step reasoning. Developers can integrate external APIs, custom plugins, and conditional logic to tailor agent behavior. The framework’s modular design ensures extensibility, enabling teams to swap components, add new capabilities, or adapt to proprietary LLMs without rewriting core logic.
