Baidu has 4 models on The Model Index, from ERNIE 4.0 (Oct 2023) to ERNIE 5.0 (13 Nov 2025). All are closed models.
Index score is fitted from independent evaluations and scaled so GPT-4 = 100; a striped bar is an estimate for a model not yet independently tested. Prices are list prices per million tokens.
Dates come from each lab's own announcement, linked where one exists.
