Lion-ER-35B-A3B: China Merchants’ Embodied Reasoning Model Released

What happened

China Merchants’ Lionshan Artificial Intelligence Laboratory released Lion-ER-35B-A3B, an embodied reasoning vision-language model with about 35B total parameters and about 3B activated per token. The article describes a capability-driven data engine behind its 312,380-sample supervised training set and reports that it improved on all ten evaluated benchmarks, with an equal-weight average of 65.29 under avg@4. The model weights are available on Hugging Face in BF16 Safetensors format.

The story so far

China Merchants’ Lion Mountain AI Laboratory released Lion-ER-35B-A3B, an embodied reasoning vision-language model with about 35 billion total parameters and 3 billion activated per token. Its BF16 Safetensors weights are available on Hugging Face and are compatible with Transformers, vLLM and SGLang. The model was trained on 312,380 supervised samples produced by a capability-driven data engine. The report says it improved on all ten evaluated benchmarks, with an equal-weight average score of 65.29 using avg@4.
