## Choose when

### Choose duet-gpt if…

- duet-gpt is primarily TypeScript; dmux is HTML.
- Pricing: Free to use; however, users need their own OpenAI API keys with potential costs based on usage..
- Tags unique to duet-gpt: agent, ai, assistant, gpt.
- You need assistance in generating or refactoring code, where DuetGPT uses the advanced capabilities of OpenAI's GPT-4 to suggest improvements or write new functions based on your specifications.

### Choose dmux if…

- dmux is primarily HTML; duet-gpt is TypeScript.
- Requirements: Does not require Docker for operation..
- Tags unique to dmux: agentic-workflow, ai-agents, coding-agents, coordinator.
- When you need to coordinate multiple AI-based coding assistants in your development process, dmux can streamline how these tools interact with your projects through its agentic workflow feature.

## When NOT to use duet-gpt

- For automated task executions where high reliability is imperative. DuetGPT may generate commands that require manual oversight before execution.
- In situations requiring strict control over function calls, as it relies on the OpenAI API's function calling feature, which might not fully cover specific enterprise workflows.

## When NOT to use dmux

- If you are looking for a tool that directly enhances the functionality of individual AI coding assistants rather than orchestrating multiple assistants, dmux may not meet your needs.
- In scenarios where developers prefer manual management of their workflows without relying on an automated agentic multiplexer like dmux.
