Baidu ships ERNIE 5.5 Flash Preview with 280B parameters on a 14B active path

Baidu released ERNIE 5.5 Flash Preview on November 11th, 2026, a model with 280 billion total parameters that activates 14 billion per token, a 1 million-token context window and generation speed above 200 tokens per second, according to Baidu's announcement on X. Baidu said the model's weights will be released under Apache 2.0 by November 25th, and the model is free on OpenRouter ahead of that release. The release tests whether a 280B model with only 14B active parameters can deliver agent-grade coding and knowledge work at small-model inference cost.

The November 25th Apache 2.0 weights release will let developers verify the speed, context, and benchmark claims outside Baidu's hosted API.
