My Take
Free access to ERNIE 4.5 and X1 makes it an obvious first stop for anyone operating in China. The API pricing is aggressively low, which matters enormously for startups and developers building for price-sensitive African markets. The Chinese language capability is unmatched, but English users will still prefer Western alternatives
