## Choose when

### Choose MassGen if…

- License: MassGen is Other, DemoGPT is MIT.
- Tags unique to MassGen: agentic-ai, cli, collaborative-ai, conversational-ai.
- When you require an open-source solution that autonomously manages collaborative interactions between multiple AI agents to produce high-quality outputs.

### Choose DemoGPT if…

- License: DemoGPT is MIT, MassGen is Other.
- Tags unique to DemoGPT: ai, chatgpt, langchain, llms.
- When you need a one-stop solution for creating LLM agents with pre-integrated tools, prompts, frameworks, and models.

## When NOT to use MassGen

- If your project requires a graphical user interface (GUI), as MassGen operates exclusively through a command-line interface.
- When you need full-scale customization beyond what is offered by its specific set of features and protocols, such as the Model Context Protocol, which may not align with alternative systems.

## When NOT to use DemoGPT

- When seeking highly specialized customization that goes beyond what is provided by integrated toolkits, since DemoGPT offers a comprehensive package which may lock you into its framework.
- If your project critically requires proprietary or private licensing terms, as it's open-source under the MIT license and might not suit projects needing more restrictive or proprietary controls.
