Baidu's ERNIE page, under product updates dated November 11, 2026, says it is releasing ERNIE 5.5 Flash Preview, the first post-trained model built on the ERNIE 5.5 Flash Base released earlier. The page says it has 280B total parameters with 14B active and a 1M-token context.

Baidu's ERNIE page, under product updates dated November 11, 2026, says it is releasing ERNIE 5.5 Flash Preview, the first post-trained model built on the ERNIE 5.5 Flash Base released earlier. The page says it has 280B total parameters with 14B active and a 1M-token context. It says the API is now available on the Qianfan platform, and that the weights will be open-sourced under Apache 2.0 soon. It does not give a date for the weights. It does not state a token price.
The page says the preview is an intermediate checkpoint from post-training, that training is not finished, and that some capabilities may still fall short. In a game-development example, the page says it is a text-only model and cannot see the screen.
What it means for business: the preview is on the Qianfan API now. The weights are described as coming under Apache 2.0, without a date. The page does not state a price. This describes the release. It is not advice on sending data to the API.
