MiniMax-Text-01
1. Introduction
MiniMax-Text-01 is a powerful language model with 456 billion total parameters, of which 45.9 billion are activated per token. To better unlock the long context capabilities of the model, MiniMax-Text-01 adopts a hybrid architecture that combines Lightning Attention, Softmax Attention and Mixture-of-Experts (MoE). Leveraging advanced parallel strategies and innovative compute-communication overlap methods—such as Linear Attention Sequence Parallelism Plus (LASP+), varlen ring attention, Expert Tensor Parallel (ETP), etc., MiniMax-Text-01's training context length is extended to 1 million tokens, and it can handle a context of up to 4 million tokens during the inference. On various academic benchmarks, MiniMax-Text-01 also demonstrates the performance of a top-tier model.
2. Model Architecture
The architecture of MiniMax-Text-01 is briefly described as follows:
- Total Parameters: 456B

4. Quickstart
Here we provide a simple example of loading the tokenizer and model to generate content.
from transformers import AutoModelForCausalLM, AutoTokenizer, AutoConfig, QuantoConfig, GenerationConfig
# load hf config
hf_config = AutoConfig.from_pretrained("MiniMaxAI/MiniMax-Text-01", trust_remote_code=True)
# quantization config, int8 is recommended
quantization_config = QuantoConfig(
weights="int8",
modules_to_not_convert=[
"lm_head",
"embed_tokens",
] + [f"model.layers.{i}.coefficient" for i in range(hf_config.num_hidden_layers)]
+ [f"model.layers.{i}.block_sparse_moe.gate" for i in range(hf_config.num_hidden_layers)]
)
# set device map
device_map = {
'model.embed_tokens': 'cuda:0',
'model.norm': f'cuda:{world_size - 1}',
'lm_head': f'cuda:{world_size - 1}'
}
# assume 8 GPUs
world_size = 8
layers_per_device = hf_config.num_hidden_layers // world_size
for i in range(world_size):
for j in range(layers_per_device):
device_map[f'model.layers.{i * layers_per_device + j}'] = f'cuda:{i}'
# load tokenizer
tokenizer = AutoTokenizer.from_pretrained("MiniMaxAI/MiniMax-Text-01")
prompt = "Hello!"
messages = [
{"role": "system", "content": [{"type": "text", "text": "You are a helpful assistant created by MiniMax based on MiniMax-Text-01 model."}]},
{"role": "user", "content": [{"type": "text", "text": prompt}]},
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
# tokenize and move to device
model_inputs = tokenizer(text, return_tensors="pt").to("cuda")
# load bfloat16 model, move to device, and apply quantization
quantized_model = AutoModelForCausalLM.from_pretrained(
"MiniMaxAI/MiniMax-Text-01",
torch_dtype="bfloat16",
device_map=device_map,
quantization_config=quantization_config,

offload_buffers=True,
)
# generate response
generation_config = GenerationConfig(
max_new_tokens=20,
eos_token_id=200020,
use_cache=True,
)
generated_ids = quantized_model.generate(**model_inputs, generation_config=generation_config)
print(f"generated_ids: {generated_ids}")
generated_ids = [
