Fojin and Surge AI serve entirely different missions: one is a niche Buddhist text platform for scholars, the other a high-end human feedback engine for frontier AI. If you need to query across Pali, Chinese, and Tibetan canons with AI-grounded answers, Fojin is your only choice. If you're training or evaluating advanced LLMs and need expert-grade RLHF, red teaming, or benchmarks like Antidote and Riemann-bench, Surge AI is the clear winner. Choose based on your domain—religious studies vs. AI alignment.
