Moriarty mcG OP : Xiaomi recently unveiled MiMo, its first open-source large language model (LLM) designed for reasoning tasks, announced on April 30, 2025. Here’s a detailed breakdown based on available information:What is MiMo?MiMo (likely standing for "Mindful Model" or a similar term, though not explicitly defined) is a 7-billion-parameter LLM series, trained from scratch by Xiaomi’s LLM-Core Team for mathematics, coding, and general reasoning tasks. It’s optimized through pre-training and post-training (reinforcement learning, or RL) to enhance reasoning capabilities.The MiMo-7B series includes:MiMo-7B-Base: Pre-trained on ~25 trillion tokens with a multi-token prediction objective to boost performance and inference speed.MiMo-7B-SFT: A supervised fine-tuned version.MiMo-7B-RL: RL-tuned from the base model, excelling in math and code.MiMo-7B-RL-Zero: RL-trained from a cold-start supervised fine-tuned model, achieving 93.6% on specific benchmarks.PerformanceDespite its compact size (7B parameters), MiMo outperforms larger models like OpenAI’s closed-source o1-mini and Alibaba’s Qwen-32B-Preview on key benchmarks (e.g., AIME24, AIME25, LiveCodeBench, MATH500, GPQA-Diamond). For example, MiMo-7B-RL matches o1-mini’s performance in math and coding tasks.It uses a three-stage pre-training data mixture and RL with 130K curated math/code problems, verified by rule-based systems to ensure quality. A test difficulty-driven reward system and data resampling enhance its optimization.AvailabilityMiMo is open-source, with models available on Hugging Face (https://huggingface.co/XiaomiMiMo). Xiaomi supports inference via a forked version of vLLM, though compatibility with other engines is unverified. The team welcomes contributions and feedback at mimo@xiaomi.com.The release includes checkpoints for all model variants, aiming to benefit the broader AI community by providing insights into building reasoning-focused LLMs.SignificanceMiMo marks Xiaomi’s entry into the competitive AI landscape, showcasing its ambition beyond hardware. Posts on X highlight its compact efficiency and superior performance, with sentiments praising Xiaomi’s innovation in open-source AI.Unlike proprietary models, MiMo’s open-source nature allows developers and researchers to adapt and build upon it, potentially accelerating advancements in reasoning-focused AI applications

Moriarty mcG : I'm here

Saywallahcuzzy OP Moriarty mcG : we are flying together

Moriarty mcG Saywallahcuzzy OP : We are indeed. 50 soon

Moriarty mcG Saywallahcuzzy OP : I thought the board would be buzzing today. Nope all rather subdued.

Moriarty mcG Saywallahcuzzy OP : See the MiMo news. Man this thing is going higher. A lot higher

Saywallahcuzzy : help. I'm scared of heights

Johnny Climber : I will continue to sell some after 50.

我爱Mikasa Johnny Climber : Bro, it may break new highs again before the Earnings Reports are released in May.

Johnny Climber 我爱Mikasa : I will sell some to free up some money, but still kept a base position. Recently sold quite a bit of Xiaomi at around 48.3 to have money to buy the bubbles.

Moriarty mcG OP : Xiaomi’s In-House Chipset’s Specification Details Come Through; Rumor Claims That SoC Will Be Mass Produced On TSMC’s 4nm ‘N4P’ But Will Stick To ARM’s Current CPU Designs

Moriarty mcG OP : The XRING SoC positions Xiaomi to compete more aggressively in the premium smartphone market, with potential to reshape its role in the semiconductor industry if successful. Official details are still pending, so some specs remain speculative.

别看我我 Moriarty mcG OP : It means that on May 2nd, Xiaomi will soar to great heights.
