Xiaomi's MiMo is a 7B-parameter reasoning language model trained from pretraining through posttraining with reinforcement learning, released with model weights on HuggingFace and a technical report. The repository provides the training methodology, model checkpoints, and evaluation results showing strong math and code reasoning performance.

Use cases

• run a small reasoning LLM for math problems
• evaluate a 7B model on AIME and LiveCodeBench
• study RL posttraining for language model reasoning
• download open weights for a reasoning model
• compare small reasoning models against DeepSeek R1
• fine-tune a base model for code and math reasoning

When to choose

• you need an open-weights 7B reasoning model for math or code
• you want to reproduce or study pretraining-to-posttraining RL pipelines
• you need strong reasoning performance on limited hardware

When to avoid

• you need a general-purpose chat assistant rather than a reasoning model
• you require a model larger than 7B parameters
• you want a production inference server rather than model weights and training research
