The global DeepSeek reappearance frenzy! The myth of Silicon Valley giants collapses, 30 knives witness the aha moment

就在这当口，全球复现DeepSeek的一波狂潮也来了。更令人兴奋的是，成本不到30美金，就可以亲眼见证「啊哈」时刻。7B模型复刻，结果令人惊讶港科大助理教授何俊贤的团队，只用了8K个样本，就在7B模型上复刻出了DeepSeek-R1-Zero和DeepSeek-R1的训练。与DeepSeek R1类似，研究者的强化学习方案极其简单，没有使用奖励模型或MCTS类技术。随后，生成长度开始再次增加，此时出现了自我反思机制。

style=\"text-align: center;\">Part 1: SimpleRL-Zero (Reinforcement Learning from Scratch)</h3>Next, the researcher shared with us the dynamic analysis of the training process and some interesting emergence patterns.</p><p><h4 id=\"id_606216327\">Dynamic Analysis of Training Process</h4>As shown below, the accuracy of all benchmarks is steadily improving during training, while the output length shows a trend of first decreasing and then gradually increasing.</p><p>After further investigation, the researchers found that the Qwen2.5-Math-7B basic model tends to generate a large amount of code in the initial stage, which may be due to the distribution characteristics of the original training data of the model.</p><p>The first drop in output length is because reinforcement learning training gradually eliminates this code generation pattern and instead learns to use natural language for reasoning.</p><p>Subsequently, the generation length began to increase again, at which point a self-reflective mechanism emerged.</p><p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/c617c450f7e378da91201c2612d6b7dc\" alt=\"训练奖励和输出长度\" title=\"训练奖励和输出长度\" tg-width=\"1076\"

described in the DeepSeek-R1 paper.</p><p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/60580dff773b0a70b356c7267119e819\" alt=\"\" title=\"\" tg-width=\"1054\"

a long CoT SFT warm-up before performing reinforcement learning, using 8,000 MATH sample responses extracted from QwQ-32B-Preview as the SFT dataset.</p><p>The potential advantage of this cold start is that the model already has a long CoT thinking mode and self-reflection ability when starting reinforcement learning, which may achieve faster and better learning results during the reinforcement learning stage.</p><p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/c761a6c0f0b865f5c1645cc06ad9869e\" alt=\"\" title=\"\" tg-width=\"1053\" tg-height=\"445\"/></p><p>Compared with the pre-RL training model (Qwen2.5-Math-7B-Base + 8K QwQ knowledge distillation version), the average performance of Qwen2.5-7B-SimpleRL is significantly improved by 6.9 percentage points.</p><p>Furthermore, not only does Qwen2.5-7B-SimpleRL consistently outperform Eurus-2-7B-PRIME, it also surpasses Qwen2.5-7B-SimpleRL-Zero on 3 out of 5 benchmarks.</p><p><h3

Qwen2.5-SimpleRL was similar to that of Qwen2.5-SimpleRL-Zero.</p><p>Interestingly, although the researchers first performed long CoT SFT, the reduction in output length was still observed in the early stage of reinforcement learning.</p><p>They speculate that this may be because the inference patterns extracted from QwQ are not suitable for the small strategy model, or are beyond its capabilities.</p><p>Therefore, the model chooses to abandon this model and instead independently develop new long-chain reasoning methods.</p><p>Finally, the researcher summed up the research with a

shows a trend of first decreasing and then gradually increasing.</p><p>After further investigation, the researchers found that the Qwen2.5-Math-7B basic model tends to generate a large amount of code in the initial stage, which may be due to the distribution characteristics of the original training data of the model.</p><p>The first drop in output length is because reinforcement learning training

a long CoT SFT warm-up before performing reinforcement learning, using 8,000 MATH sample responses extracted from QwQ-32B-Preview as the SFT dataset.</p><p>The potential advantage of this cold start

R1-Zero。他们表示，结果相当出色！实验中，团队验证了通过强化学习RL，3B的基础语言模型也能够自我验证和搜索。更令人兴奋的是，成本不到30美金（约217元），就可以亲眼见证「啊哈」时刻。这个项目叫做TinyZero，采用了R1-Zero算法——给定一个基础语言模型、提示和真实奖励信号，运行强化学习。然后，团队将其应用在CountDown游戏中（这是一个玩家使用基础算术运算，将数字组合以达到目标数字的游戏）。模型从最初的简单输出开始，逐步进化出自我纠正和搜索的策略。在以下示例中，模型提出了解决方案，自我验证，并反复纠正，直到解决问题为止。在消融实验中，研究人员运行了Qwen-2.5-Base（0.5B、1.5B、3B、7B四种参数规模）。结果发现，0.5B模型仅仅是猜测一个解决方案然后停止。而从1.5B开始，模型学会了搜索、自我验证和修正其解决方案，从而能够获得更高的分数。他们认为，在这个过程，基础模型的是性能的关键。他们还验证了，额外的指令微调（SFT）并非是必要的，这也印证了R1-Zero的设计决策。这是首个验证LLM推理能力的实现可以纯粹通过RL，无需监督微调的开源研究基础模型和指令模型两者区别：指令模型运行速度快，但最终表现与基础模型相当指令输出的模型更具结构性和可读性此外，他们还发现，具体的RL算法并不重要。PPO、GRPO、PRIME这些算法中，长思维链（Long CoT）都能够涌现，且带来不错的性能表现。而且，模型在推理行为中非常依赖于具体的任务：对于Countdow任务，模型学习进行搜索和自我验证对于数字乘法任务，模型反而学习使用分布规则分解问题，并逐步解决苹果机器学习科学家Yizhe Zhang对此表示，太酷了，小到1.5B的模型，也能通过RL涌现出自我验证的能力。7B模型复刻，结果令人惊讶港科大助理教授何俊贤的团队（共同一作黄裕振、Weihao Zeng），只用了8K个样本，就在7B模型上复刻出了DeepSeek-R1-Zero和DeepSeek-R1的训练。结果令人惊喜——模型在复杂的数学推理上取得了十分强劲结果。项目地址：https://github.com/hkust-nlp/simpleRL-reason他们以Qwen2.5-Math-7B（基础模型）为起点，直接对其进行强化学习。整个过程中，没有进行监督微调（SFT），也没有使用奖励模型。最终，模型在AIME基准上实现了33.3%的准确率，在AMC上为62.5%，在MATH上为77.2%。这一表现不仅超越了Qwen2.5-Math-7B-Instruct，并且还可以和使用超过50倍数据量和更复杂组件的PRIME和rStar-MATH相媲美！其中，Qwen2.5-7B-SimpleRL-Zero是在Qwen2.5-Math-7B基础模型上仅使用纯PPO方法训练的，仅采用了MATH数据集中的8K样本。Qwen2.5-7B-SimpleRL则首先通过Long CoT监督微调（SFT）作为冷启动，然后再进行强化学习。在这两种方法中，团队都只使用了相同的8K MATH样本，仅此而已。大概在第44步的时候，「啊哈时刻」出现了！模型的响应中，出现了自我反思。并且，在这个过程中，模型还显现了更长的CoT推理能力和自我反思能力。在博客中，研究者详细剖析了实验设置，以及在这个强化学习训练过程中所观察到的现象，例如长链式思考（CoT）和自我反思机制的自发形成。与DeepSeek R1类似，研究者的强化学习方案极其简单，没有使用奖励模型或MCTS（蒙特卡洛树搜索）类技术。他们使用的是PPO算法，并采用基于规则的奖励函数，根据生成输出的格式和正确性分配奖励：如果输出以指定格式提供最终答案且正确，获得+1的奖励如果输出提供最终答案但不正确，奖励设为-0.5如果输出未能提供最终答案，奖励设为-1该实现基于OpenRLHF。初步试验表明，这个奖励函数有助于策略模型快速收敛，产生符合期望格式的输出。第一部分：SimpleRL-Zero（从头开始的强化学习）接下来，研究者为我们分享了训练过程动态分析和一些有趣的涌现模式。训练过程动态分析如下所示，所有基准测试的准确率在训练过程中都在稳步提高，而输出长度则呈现先减少后逐渐增加的趋势。经过进一步调查，研究者发现，Qwen2.5-Math-7B基础模型在初始阶段倾向于生成大量代码，这可能源于模型原始训练数据的分布特征。输出长度的首次下降，是因为强化学习训练逐渐消除了这种代码生成模式，转而学会使用自然语言进行推理。随后，生成长度开始再次增加，此时出现了自我反思机制。训练奖励和输出长度基准测试准确率（pass@1）和输出长度自我反思机制的涌现在训练到第 40 步左右时，研究者观察到：模型开始形成自我反思模式，这正是DeepSeek-R1论文中所描述的「aha moment」（顿悟时刻）。第二部分：SimpleRL（基于模仿预热的强化学习）如前所述，研究者在进行强化学习之前，先进行了long CoT SFT预热，使用了8,000个从QwQ-32B-Preview中提取的MATH示例响应作为SFT数据集。这种冷启动的潜在优势在于：模型在开始强化学习时已具备long CoT思维模式和自我反思能力，从而可能在强化学习阶段实现更快更好的学习效果。与RL训练前的模型（Qwen2.5-Math-7B-Base + 8K QwQ知识蒸馏版本）相比，Qwen2.5-7B-SimpleRL的平均性能显著提升了6.9个百分点。此外，Qwen2.5-7B-SimpleRL不仅持续优于Eurus-2-7B-PRIME，还在5个基准测试中的3个上超越了Qwen2.5-7B-SimpleRL-Zero。训练过程分析训练奖励和输出长度基准测试准确率（pass@1）和输出长度Qwen2.5-SimpleRL的训练动态表现与Qwen2.5-SimpleRL-Zero相似。有趣的是，尽管研究者先进行了long CoT SFT，但在强化学习初期仍然观察到输出长度减少的现象。他们推测，这可能是因为从QwQ提取的推理模式不适合小型策略模型，或超出了其能力范围。因此，模型选择放弃这种模式，转而自主发展新的长链式推理方式。最后，研究者用达芬奇的一句话，对这项研究做了总结——简约，便是最终极的精致。图片完全开源复刻，HuggingFace下场了甚至，就连全球最大开源平台HuggingFace团队，今天官宣复刻DeepSeek R1所有pipeline。复刻完成后，所有的训练数据、训练脚本等等，将全部开源。这个项目叫做Open R1，当前还在进行中。发布到一天，星标冲破1.9k，斩获142个fork。项目地址：https://github.com/huggingface/open-r1研究团队以DeepSeek-R1技术报告为指导，将整个复刻过程划分为三个关键步骤。步骤 1：通过从DeepSeek-R1蒸馏高质量语料库，复现R1-Distill模型。步骤 2：复现DeepSeek用于创建R1-Zero的纯强化学习（RL）流程。这可能需要为数学、推理和代码任务策划新的大规模数据集。步骤 3：展示我们如何通过多阶段训练，从基础模型发展到经过RL调优的模型。从斯坦福到MIT，R1成为首选一个副业项目，让全世界科技大厂为之惶恐。DeepSeek这波成功，也成为业界的神话，网友最新截图显示，这款应用已经在APP Store「效率」应用榜单中挤进前三。在Hugging Face中，R1下载量直接登顶，另外3个模型也霸占着热榜。a16z合伙人Anjney Midha称，一夜之间，从斯坦福到MIT，DeepSeek R1已经成为美国顶尖高校研究人员「首选模型」。还有研究人员表示，DeepSeek基本上取代了我用ChatGPT的需求。中国AI，这一次真的震撼了世界。","news_type":1,"symbols_score_info":{}},"isVote":1,"tweetType":1,"viewCount":664,"commentLimit":10,"likeStatus":false,"favoriteStatus":false,"reportStatus":false,"symbols":[],"verified":2,"subType":0,"readableState":1,"langContent":"EN","currentLanguage":"EN","warmUpFlag":false,"orderFlag":false,"shareable":true,"causeOfNotShareable":"","featuresForAnalytics":[],"commentAndTweetFlag":false,"andRepostAutoSelectedFlag":false,"upFlag":false,"length":3,"optionInvolvedFlag":false,"xxTargetLangEnum":"ORIG"},"commentList":[],"hasMoreComment":false,"orderType":2}
