Frequently Asked Questions
Ragpi vs Surge AI: which should you choose?
Ragpi is the right choice if you need a free, open-source AI assistant for your technical documentation—self-host it to keep data private. Surge AI is for advanced AI labs that require expert human feedback for RLHF and red teaming, backed by demanding benchmarks. Choose based on whether you need to answer user questions or improve model alignment.
Can Ragpi handle PDF or image sources?
No, Ragpi currently only supports documentation sitemaps, GitHub Issues, and READMEs. It is not designed for non-technical content like PDFs or images.
Is Surge AI a fully automated evaluation tool?
No, Surge AI is a human-in-the-loop platform. It uses expert graders and red teamers, not automated metrics.
Does Ragpi require a paid LLM API key?
Yes, you must bring your own LLM provider (e.g., OpenAI, Anthropic). The Ragpi software itself is free.
What makes Surge AI's benchmarks different?
Surge's benchmarks (Riemann-bench, GDP.pdf, ComplexConstraints) are designed to expose failures even frontier models face, graded by domain experts.
Can I self-host Surge AI?
No, Surge AI is a cloud-based platform accessed via SDK/API. Ragpi is the self-hosted option.
Which tool is better for a non-technical user?
Ragpi requires technical setup (self-hosting, API configuration). Surge AI is managed but requires a budget. Neither is plug-and-play for non-technical users.
How does Ragpi ensure data privacy?
Since it's self-hosted, all data stays on your own infrastructure. Surge AI uses experts who see data, so review their security posture.
Does Surge AI offer RLHF for small projects?
It targets teams with funding for expert labor. For small projects, simpler automated tools might be more cost-effective.
