Research & Cutting-Edge Agents

AlphaEvolve (Google DeepMind)

AlphaEvolve is an evolutionary coding agent powered by Gemini. It autonomously invents and optimizes algorithms across various domains, including mathematics, data center scheduling, chip design, and language model training. This general-purpose system improves and discovers state-of-the-art solutions to a wide range of algorithmic problems, requiring only a user-defined evaluation function.

Asimov (Reflection)

Developed by Reflection, Asimov is a modular, multi-agent software engineering assistant that emphasizes code comprehension and team-wide collaboration. It integrates multiple communication and data sources, such as code, emails, Slack, and documents. Evaluations indicate that developers prefer its responses over Claude Code in open-source project settings, although broader industry evaluations are ongoing.

Manus

Manus is a general-purpose, multi-agent autonomous AI system. It employs a central executor that collaborates with specialized sub-agents (planners, verifiers, etc.) to independently plan, reason, and execute complex tasks—such as building websites, drafting emails, coding, and data gathering—without ongoing user input. Manus operates asynchronously and is designed for hands-off automation.

AutoGPT

This open-source system is one of the first autonomous GPT-4 agents, capable of planning and executing multi-step tasks via the internet. AutoGPT organizes goals, breaks them into subtasks, and manages the process with minimal user involvement, pioneering LLM-driven agentic workflows.

OpenAI Operator

Operator is a browser-based agent that autonomously manages repetitive web tasks—such as filling forms, shopping, and scheduling—by visually interacting with websites. It utilizes GPT-4o’s multimodal capabilities and is available to Pro users for a growing set of real-world applications.

Frameworks & SDKs

Microsoft AutoGen / Autogen

This comprehensive SDK facilitates the development of collaborative, multi-agent systems. It features modular architecture, error handling, logging, message-passing, containerized execution, and supports both human-in-the-loop and fully autonomous workflows.

LangGraph

LangGraph is a stateful orchestration framework that enables the creation of agent workflows with graph-based chaining. Key features include integrated memory, support for cyclical flows, and robust orchestration and deployment tooling.

Semantic Kernel (Microsoft)

This open-source SDK connects LLMs (C#, Python, Java) with application logic, enabling planning, function-calling, prompt templating, and composing advanced orchestrated agent behaviors with enterprise-grade reliability and extensibility.

CrewAI

CrewAI is a flexible, role-based multi-agent framework designed for quickly prototyping custom “crews” (modular agents) and agent teams, built on LangChain for interoperability.

OpenAI Swarm

This lightweight experimental toolkit aims to study multi-agent coordination patterns using OpenAI models.

Toolkits & Low-Code Platforms
