Community: ByteDance technical support, fast domestic rollout.

MetaGPT – Multi‑agent collaborative development framework; role‑based dynamic task allocation (product manager / architect / engineer), multi‑model support, human‑team simulation. Scenarios: complex organization modeling (software development lifecycle), debate simulation, multi‑role collaboration (supply‑chain coordination). Cost: open‑source free + model API fees. Community: high activity, multilingual model integration.

OpenAI Agents – Enterprise‑grade AI‑native application framework; deep integration of GPT‑4o/5, low‑code workflow design, extensible toolchain (search / API calls), enterprise security (access control / audit logs). Scenarios: intelligent customer service (CRM), data analysis assistants (SQL + Power BI), permission‑aware knowledge management. Cost: usage‑based cloud pricing (e.g., $12 per 1k queries). Community: official OpenAI support, extensive documentation.

Google ADK – Cloud‑native multimodal agent development kit; deep integration of Gemini 2.0 multimodal model, Vertex AI managed services, visual debugging tools. Scenarios: enterprise‑level multimodal interaction (video analysis / real‑time translation), production‑grade deployment (high concurrency, elastic scaling). Cost: usage‑based cloud pricing (e.g., $12 per 1k queries). Community: Google technical support, suited for existing GCP users.

CrewAI – Role‑based multi‑agent collaboration framework; dynamic task allocation, human‑team simulation, customizable agent behavior. Scenarios: complex organization modeling (project management / supply‑chain), collaborative simulation training (emergency response / education). Cost: open‑source free + enterprise customization fees. Community: moderate activity, Python SDK provided.

Agno – Multi‑agent collaborative development framework; role‑based dynamic task allocation, custom behavior, human‑team simulation, supports multiple models (LLaMA / Flan‑T5). Scenarios: complex organization modeling, collaborative simulation training. Cost: open‑source free + model API fees. Community: moderate activity, Python SDK.

Selection Recommendations

1. Complex Process Management

LangGraph – suitable for enterprise scenarios requiring state persistence, human intervention, and audit trails (e.g., healthcare, finance). Dify – low‑code entry with enterprise‑grade security, ideal for rapid business‑process and knowledge‑center deployment.

2. Multi‑Agent Collaboration

AutoGen – distributed deployment and conversational programming, fits cross‑department collaboration and distributed applications. MetaGPT – team role simulation and SOP workflow, suited for software development and vertical‑domain automation.

3. Rapid Prototyping

Dify/Coze – visual workflow building and plugin ecosystem, perfect for non‑technical users to create lightweight AI tools. OpenAI Agents – minimal integration relying on OpenAI API, good for quick validation of tool‑calling scenarios.

4. Enterprise‑Level Compliance

Dify – ISO 27001 certification and private deployment, meets data‑security demands of finance and healthcare. OpenAI Agents – five‑layer security and compliance auditing, suitable for handling sensitive decision‑making data.

5. Cost‑Sensitive Projects

LangGraph/AutoGen/MetaGPT – open‑source frameworks lower initial investment, fit teams capable of self‑development. Dify/Coze – free tier and pay‑as‑you‑go models, enable fast PoC building with low‑cost experimentation.

Conclusion

Technical Depth : LangGraph, AutoGen, and MetaGPT excel in complex logic and multi‑agent collaboration, ideal for deep customization by technical teams.

Deployment Speed : Dify and Coze dramatically shorten development cycles through low‑code/no‑code capabilities, fitting business‑driven projects.

Ecosystem Dependence : OpenAI Agents heavily rely on OpenAI APIs, offering stability and compliance; other frameworks provide more self‑controlled options.

Long‑Term Cost : Private deployment (Dify, LangGraph) suits sustained operations; SaaS subscriptions (Coze, OpenAI) suit flexible, short‑term scaling.

Enterprises should choose based on internal technical reserves, business scenarios, and budget, possibly combining frameworks (e.g., Dify + MetaGPT) to meet composite requirements.
