Frequently Asked Questions
Everything you need to know about using TestDummy
What AI models are supported?
We support 20+ models including GPT-4, GPT-3.5, Claude 3.5 Sonnet, Claude 3 Haiku, Gemini Pro, Llama 2, and many more. Models are sourced through OpenRouter, giving you access to the latest AI capabilities from multiple providers.
How does side-by-side testing work?
You can create multiple panels, each running a different AI model. When sync is enabled, the same prompt is sent to all panels simultaneously, allowing you to compare responses in real-time. You can also test different configurations independently.
What are MCP servers and how do I use them?
Model Context Protocol (MCP) servers provide external tools and data sources that AI models can use. You can connect MCP servers to test how different models interact with databases, APIs, file systems, and other external resources.
Is TestDummy free to use?
Yes! TestDummy is free to use. You'll need to provide your own API keys for the AI models you want to test. This gives you direct access to the models while keeping costs transparent and under your control.
Can I save and export my test results?
Yes, all conversations are automatically saved to your account. You can view conversation history, export chat logs, and analyze performance metrics over time to make informed decisions about which models work best for your use cases.
