# Glm4Moe ## Overview The [**GLM-4.5**](https://huggingface.co/papers/2508.06471) series models are foundation models designed for intelligent agents, MoE variants are documented here as Glm4Moe. GLM-4.5 has **355** billion total parameters with **32** billion active parameters, while GLM-4.5-Air adopts a more compact design with **106** billion total parameters and **12** billion active parameters. GLM-4.5 models unify reasoning, coding, and intelligent agent capabilities to meet the complex demands of intelligent agent applications. Both GLM-4.5 and GLM-4.5-Air are hybrid reasoning models that provide two modes: thinking mode for complex reasoning and tool usage, and non-thinking mode for immediate responses. We have open-sourced the base models, hybrid reasoning models, and FP8 versions of the hybrid reasoning models for both GLM-4.5 and GLM-4.5-Air. They are released under the MIT open-source license and can be used commercially and for secondary development. As demonstrated in our comprehensive evaluation across 12 industry-standard benchmarks, GLM-4.5 achieves exceptional performance with a score of **63.2**, in the **3rd** place among all the proprietary and open-source models. Notably, GLM-4.5-Air delivers competitive results at **59.8** while maintaining superior efficiency. ![bench](https://raw.githubusercontent.com/zai-org/GLM-4.5/refs/heads/main/resources/bench.png) For more eval results, show cases, and technical details, please visit our [technical report](https://huggingface.co/papers/2508.06471) or [technical blog](https://z.ai/blog/glm-4.5). The model code, tool parser and reasoning parser can be found in the implementation of [transformers](https://github.com/huggingface/transformers/tree/main/src/transformers/models/glm4_moe), [vLLM](https://github.com/vllm-project/vllm/blob/main/vllm/model_executor/models/glm4_moe_mtp.py) and [SGLang](https://github.com/sgl-project/sglang/blob/main/python/sglang/srt/models/glm4_moe.py). ## Glm4MoeConfig[[transformers.Glm4MoeConfig]] #### transformers.Glm4MoeConfig[[transformers.Glm4MoeConfig]] [Source](https://github.com/huggingface/transformers/blob/v4.57.1/src/transformers/models/glm4_moe/configuration_glm4_moe.py#L26) This is the configuration class to store the configuration of a [Glm4MoeModel](/docs/transformers/v4.57.1/en/model_doc/glm4_moe#transformers.Glm4MoeModel). It is used to instantiate a Glm4Moe model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of [THUDM/GLM-4-100B-A10B](https://huggingface.co/THUDM/GLM-4-100B-A10B). Configuration objects inherit from [PretrainedConfig](/docs/transformers/v4.57.1/en/main_classes/configuration#transformers.PretrainedConfig) and can be used to control the model outputs. Read the documentation from [PretrainedConfig](/docs/transformers/v4.57.1/en/main_classes/configuration#transformers.PretrainedConfig) for more information. ```python >>> from transformers import Glm4MoeModel, Glm4MoeConfig >>> # Initializing a Glm4Moe style configuration >>> configuration = Glm4MoeConfig() >>> # Initializing a model from the GLM-4-MOE-100B-A10B style configuration >>> model = Glm4MoeModel(configuration) >>> # Accessing the model configuration >>> configuration = model.config ``` **Parameters:** vocab_size (`int`, *optional*, defaults to 151552) : Vocabulary size of the Glm4Moe model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [Glm4MoeModel](/docs/transformers/v4.57.1/en/model_doc/glm4_moe#transformers.Glm4MoeModel) hidden_size (`int`, *optional*, defaults to 4096) : Dimension of the hidden representations. intermediate_size (`int`, *optional*, defaults to 10944) : Dimension of the MLP representations. num_hidden_layers (`int`, *optional*, defaults to 46) : Number of hidden layers in the Transformer encoder. num_attention_heads (`int`, *optional*, defaults to 96) : Number of attention heads for each attention layer in the Transformer encoder. partial_rotary_factor (`float`, *optional*, defaults to 0.5) : The factor of the partial rotary position. num_key_value_heads (`int`, *optional*, defaults to 8) : This is the number of key_value heads that should be used to implement Grouped Query Attention. If `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed by meanpooling all the original heads within that group.

The original max position embeddings used during pretraining. `attention_factor` (`float`, *optional*): Used with 'yarn' and 'longrope'. The scaling factor to be applied on the attention computation.

Contains pre-computed hidden-states (key and values in the self-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding. - **hidden_states** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_hidden_states=True` is passed or when `config.output_hidden_states=True`) -- Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, + one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`. Hidden-states of the model at the output of each layer plus the optional initial embedding outputs. - **attentions** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_attentions=True` is passed or when `config.output_attentions=True`) -- Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, num_heads, sequence_length, sequence_length)`. Attentions weights after the attention softmax, used to compute the weighted average in the self-attention heads.
