FMAS (Flexible Multi-Agent System) is an open-source Python library for building, running, and visualizing multi-agent simulations. You can define agents with custom decision logic, configure an environment model, set up messaging channels for communication, and execute scalable simulation runs. FMAS provides hooks for monitoring agent state, debugging interactions, and exporting results. Its modular architecture supports plugins for visualization, metrics collection, and integration with external data sources, making it ideal for research, education, and real-world prototypes of autonomous systems.

At its core, LionAGI provides a modular architecture for defining and executing dependent task stages, breaking complex problems into logical components that can be processed sequentially or in parallel. Each stage can leverage a custom prompt, memory storage, and decision logic to adapt behavior based on previous results. Developers can integrate any supported LLM API or self-hosted model, configure observation spaces, and define action mappings to create agents that plan, reason, and learn over multiple cycles. Built-in logging, error recovery, and analytics tools enable real-time monitoring and iterative refinement. Whether automating research workflows, generating reports, or orchestrating autonomous processes, LionAGI accelerates the delivery of intelligent, adaptable AI agents with minimal boilerplate.

LinkAgent provides a lightweight microkernel for building AI agents with pluggable components. Users can register language model backends, retrieval modules, and external APIs as tools, then assemble them into workflows using built-in planners and routers. LinkAgent supports memory handlers for context persistence, dynamic tool invocation, and configurable decision logic for complex multi-step reasoning. With minimal code, teams can automate tasks like QA, data extraction, process orchestration, and report generation.

sma-begin sets up a streamlined codebase to create AI-driven agents by abstracting common components like input processing, decision logic, and output generation. At its core, it implements an agent loop that queries an LLM, interprets the response, and optionally executes integrated tools, such as HTTP clients, file handlers, or custom scripts. Memory modules allow the agent to recall previous interactions or context, while prompt chaining supports multi-step workflows. Error handling catches API failures or invalid tool outputs. Developers only need to define the prompts, tools, and desired behaviors. With minimal boilerplate, sma-begin accelerates prototyping of chatbots, automation scripts, or domain-specific assistants on any Python-supported platform.
