LLM Test Report & API Key Check

Zhidu issues standardized platform capability evaluation reports for mainstream LLMs (6 dimensions: engineering, accuracy, performance, capacity, availability, cache, plus key qualification). Online key check: validity, auth, rate limits and suspected reverse/over-issue flags. Test-and-discard, key never stored or forwarded.

• Key 体检：paste API key to check validity and suspected reverse/over-issue
• 评估报告：standard evaluation reports for all major LLMs, with deep tests scheduled
• 即测即弃：auth probe only, no billing, no storage, logs only keep masked key
