Baidu ERNIE 5.1 and efficient multimodal scaling
ERNIE 5.1 is worth tracking because Baidu is talking about model compression, elastic pre-training, agentic post-training, and cost-performance.

Why I saved it
This is a useful Chinese AI lab read because it is not only about a bigger model. Baidu talks about making ERNIE 5.1 cheaper and more efficient while keeping strong capability.
That balance is the real game now.
My notes
- ERNIE 5.1 inherits from ERNIE 5.0 but reduces total and active parameters.
- Baidu describes multi-dimensional elastic pre-training.
- The post highlights agentic capability, reasoning, knowledge, and search leaderboard results.
- The technical direction is about capability per unit of compute.
What I want to remember
Model progress is not only scale. Efficient training, sparse activation, routing, and post-training can change what is possible at production cost.
