LG AI Research renamed the architecture from ExaoneMoEForCausalLM to ExaoneMoeForCausalLM when exaone_moe was upstreamed into Transformers v5, and updated the configs of already-released models accordingly (K-EXAONE-236B-A23B config.json, commit f7db87a, "Update README.md and config.json for Transformers v5"). Freshly downloaded K-EXAONE-236B-A23B and K-EXAONE-2.0-750B-A37B checkpoints therefore fail conversion with ERROR:hf-to-gguf:Model ExaoneMoeForCausalLM is not supported even though the architecture is implemented. The spelling comes from the checkpoint's own config.json, so it is unaffected by the installed Transformers version. Register both spellings so that older local copies keep working, as is already done for e.g. BitNet. Note this fixes the architecture lookup only. K-EXAONE-236B-A23B converts correctly with this change alone; K-EXAONE-2.0-750B-A37B additionally needs support for its two leading dense layers (declared via mlp_layer_types rather than first_k_dense_replace), its per-layer sliding windows of 0/128/4096, and clamped SwiGLU on layers 62-77.
