Xiaomi Miclaw AI Beta Testing Begins

🔑 Enhanced Key Takeaways

• •MiMo is a 7B parameter large language model series from Xiaomi, optimized for reasoning tasks through pre-training on 25 trillion tokens and Multi-Token Prediction (MTP) for faster inference[1][2][4].
• •MiMo-7B-RL variant matches OpenAI o1-mini performance on math and code reasoning benchmarks after reinforcement learning on 130K verifiable problems[2][3][4].
• •Xiaomi released MiMo-V2-Flash in late 2025, a 309B MoE model with 15B active parameters for efficient high-performance inference[5][6][7].

🛠️ Technical Deep Dive

• •MiMo-Audio variant uses high-fidelity RVQ tokenization for near-lossless speech representation, enabling unified autoregressive processing of interleaved text and audio tokens via a patch encoder, 7B LLM backbone, and patch decoder[1].
• •MiMo-7B incorporates Multi-Token Prediction (MTP) layers tuned during pretraining and SFT, achieving ~90% acceptance rate for speculative decoding and enhanced speed in long-output reasoning[2][3].
• •Pre-trained on 25T tokens with three-stage data mixing; post-training includes RL with test-difficulty-driven code-reward and data resampling for stability[4].
