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

103422390 : go for it.

103779805 OP 103422390 : Need your power too

102864101 : yes below 120 soon

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.
