About the currency conversion

ERNIE 5.1 is quoted by Baidu at ¥4 per million input tokens and ¥18 per million output. The dollar figures shown are converted at roughly ¥7.1 to the dollar and will drift as the exchange rate does. As with the other CNY-priced providers on this site, the yuan figure is authoritative and the dollar figure is a convenience.

Where ERNIE sits

Converted, ERNIE 5.1 lands near the cheap end of the mid band, below Kimi K2.5 and GLM-4.6 on input. Baidu also publishes smaller ERNIE 4.5 variants that go considerably lower, though not all of them have a confirmable output rate, so only the models with a complete rate pair appear here.

The shape of the pricing is conventional: output runs about four and a half times input, which is in line with the industry norm and unlike the flat-rate structures Perplexity uses on some tiers.
