This repository is primarily for the Transformers framework. If you're using other open-source frameworks, please use the alternative repository: MiniMax-Text-01
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.

5. Deployment Guide
For production deployment, we recommend using vLLM to serve MiniMax-Text-01. vLLM provides excellent performance for serving large language models with the following features:
MiniMax-Text-01 supports Function Calling capability, enabling the model to intelligently identify when external functions need to be called and output parameters in structured JSON format. With Function Calling, you can:
Let the model recognize implicit function call needs in user requests
Receive structured parameter outputs for seamless application integration
Support various complex parameter types, including nested objects and arrays
Function Calling supports standard OpenAI-compatible format definitions and integrates seamlessly with the Transformers library. For detailed usage instructions, please refer to our Function Call Guide or Chinese Guide.
