ERNIE 5.1
ERNIE 5.1 is Baidu’s more efficient agent and reasoning model derived from ERNIE 5.0’s elastic sub-network training. It compresses total and active parameter capacity while applying asynchronous reinforcement learning and multi-teacher distillation. The hosted model targets language reasoning, creative writing, search, and tool-driven workflows. The official May 9 launch post confirms chat and AI Studio access. Absolute parameter counts and a supported context ceiling are omitted because the announcement establishes relative reductions rather than exact specifications.
