        "public_description": "ERNIE is Baidu’s foundation-model lineage. The family’s 2026 evolution moved to ERNIE 5.0 in February with unified text, image, video and audio modeling, then to ERNIE 5.1 in May with substantially reduced model size, stronger foundation capabilities and scaled agentic post-training.",

ERNIE 5.0 uses a unified autoregressive multimodal framework at 2.4T parameters; ERNIE 5.1 inherits the pretraining foundation while compressing scale and emphasizing agentic reinforcement learning and reasoning. The Entry represents the family, not one checkpoint.",
