model : fix SWA not being enabled for EXAONE 4.5 (#26848) model : fix SWA not being enabled for EXAONE 4.5 load_arch_hparams tests hparams.n_layer() == 64 before LLM_KV_NEXTN_PREDICT_LAYERS has been read. n_layer() returns n_layer_all - n_layer_nextn and n_layer_nextn defaults to 0, so a GGUF carrying the MTP head (block_count=65, nextn=1) evaluates to 65 and the whole SWA block is skipped. The model type switch further down in the same function reads 64, because by then the key has been loaded. n_swa is still filled in by the unconditional get_key below the block, so llama_model_n_swa() reports 4096 and the logs look correct while only swa_type stays LLAMA_SWA_TYPE_NONE. This affects the official LGAI-EXAONE GGUF release as well. EXAONE 4.0 has no MTP head, so block_count is 64 there and the check matches. model-loader : skip TENSOR_SKIP tensors in the metadata-only path create_tensor asserts on a null buffer type when building from metadata alone, but buft_for_tensor returns null by design for tensors marked TENSOR_SKIP, which is how architectures with nextn/MTP layers mark theirs. Those models cannot be constructed by llama_model_init_from_user at all. The file-backed path below already returns nullptr for the same tensors, so callers see the same thing either way. tests : cover exaone4 hparams ordering Builds a synthetic exaone4 model with the layout the shipped EXAONE 4.5 GGUFs use (block_count 65 + nextn 1). The swa_type check is the one that catches the ordering bug; the n_layer_nextn and n_layer() checks only tell a broken fixture apart from a real regression. Fails before the ordering fix with "swa_type is not STANDARD", passes after. Revert "tests : cover exaone4 hparams ordering" This reverts commit d2f3baf. Revert "model-loader : skip TENSOR_SKIP tensors in the metadata-only path" This reverts commit aecb9bc.
