# MiniMax-M2

## Overview

MiniMax-M2 is a compact, fast, and cost-effective MoE model (230 billion total parameters with 10 billion active parameters) built for elite performance in coding and agentic tasks, all while maintaining powerful general intelligence. With just 10 billion activated parameters, MiniMax-M2 provides the sophisticated, end-to-end tool use performance expected from today's leading models, but in a streamlined form factor that makes deployment and scaling easier than ever.

For more details refer to the [release blog post](https://www.minimax.io/news/minimax-m2).

[Source](https://github.com/huggingface/transformers/blob/v5.1.0/src/transformers/models/minimax_m2/configuration_minimax_m2.py#L26)

This is the configuration class to store the configuration of a [MiniMaxM2Model](/docs/transformers/v5.1.0/en/model_doc/minimax_m2#transformers.MiniMaxM2Model). It is used to instantiate an
MiniMaxM2 model according to the specified arguments, defining the model architecture. Instantiating a configuration
with the defaults will yield a similar configuration to that of the MiniMaxM2.

[MiniMaxAI/MiniMax-M2](https://huggingface.co/MiniMaxAI/MiniMax-M2)

Configuration objects inherit from [PreTrainedConfig](/docs/transformers/v5.1.0/en/main_classes/configuration#transformers.PreTrainedConfig) and can be used to control the model outputs. Read the
documentation from [PreTrainedConfig](/docs/transformers/v5.1.0/en/main_classes/configuration#transformers.PreTrainedConfig) for more information.

```python
>>> from transformers import MiniMaxM2Model, MiniMaxM2Config

>>> # Initializing a MiniMaxM2 style configuration
>>> configuration = MiniMaxM2Config()

>>> # Initializing a model from the MiniMaxM2 style configuration
>>> model = MiniMaxM2Model(configuration)

>>> # Accessing the model configuration
>>> configuration = model.config
```

**Parameters:**

vocab_size (`Optional`, *optional*, defaults to 200064) : Vocabulary size of the MiniMaxM2 model. Defines the number of different tokens that can be represented by the `inputs_ids` passed when calling [MiniMaxM2Model](/docs/transformers/v5.1.0/en/model_doc/minimax_m2#transformers.MiniMaxM2Model)

hidden_size (`Optional`, *optional*, defaults to 3072) : Dimension of the hidden representations.

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. For more details, check out [this paper](https://huggingface.co/papers/2305.13245). If it is not specified, will default to `8`.

head_dim (`Optional`, *optional*, defaults to 128) : The attention head dimension.

hidden_act (`str` or `function`, *optional*, defaults to `"silu"`) : The non-linear activation function (function or string) in the decoder.

max_position_embeddings (`Optional`, *optional*, defaults to 196608) : The maximum sequence length that this model might ever be used with. MiniMaxM2's sliding window attention allows sequence of up to 196608 tokens.

num_local_experts (`Optional`, *optional*, defaults to 256) : Number of experts per Sparse MLP layer.

output_router_logits (`Optional`, *optional*, defaults to `False`) : Whether or not the router logits should be returned by the model. Enabling this will also allow the model to output the auxiliary loss. See [here]() for more details

router_aux_loss_coef (`Optional`, *optional*, defaults to 0.001) : The aux loss factor for the total loss.

router_jitter_noise (`Optional`, *optional*, defaults to 0.0) : Amount of noise to add to the router.

The [MiniMaxM2Model](/docs/transformers/v5.1.0/en/model_doc/minimax_m2#transformers.MiniMaxM2Model) forward method, overrides the `__call__` special method.

instance afterwards instead of this since the former takes care of running the pre and post processing steps while
the latter silently ignores them.

- **logits** (`torch.FloatTensor` of shape `(batch_size, sequence_length, config.vocab_size)`) -- Prediction scores of the language modeling head (scores for each vocabulary token before SoftMax).

- **aux_loss** (`torch.FloatTensor`, *optional*, returned when `labels` is provided) -- aux_loss for the sparse modules.

- **router_logits** (`tuple(torch.FloatTensor)`, *optional*, returned when `output_router_probs=True` and `config.add_router_probs=True` is passed or when `config.output_router_probs=True`) -- Tuple of `torch.FloatTensor` (one for each layer) of shape `(batch_size, sequence_length, num_experts)`.

  Raw router logtis (post-softmax) that are computed by MoE routers, these terms are used to compute the auxiliary
  loss for Mixture of Experts models.

- **past_key_values** (`Cache`, *optional*, returned when `use_cache=True` is passed or when `config.use_cache=True`) -- It is a [Cache](/docs/transformers/v5.1.0/en/internal/generation_utils#transformers.Cache) instance. For more details, see our [kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache).

  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.
