在GPT-5发布之前，Information曾报道称，GPT-5的性能提升主要来自其研发出的"通用验证器"（Universal Verifier）。 虽然GPT-5后续的能力升级不及预期，但通用验证器却已经成了大模型的下一个"圣杯"，近期内成了AI圈内最近最热的话题之一。 为什么它这么关键？ 这主要是因为上一波模型能力提升所倚仗的技术是"可验证奖励强化学习"（Reinforcement learning with verifiable rewards, RLVR）。简单说，就是先从 数学、编程这类有标准答案的问题入手：答对加分，答错扣分，训练效果立竿见影。 但现实世界远比"对"与"错"复杂。比如医疗、教育、创意领域，很多问题根本没有唯一解答，一个"好"的答案可能既要专业可靠，又要体现沟通和共情。 RLVR在这些场景下就显得力不从心，甚至让模型在开放性问题上退步。 要让模型进一步进化，就必须突破"对/错"奖励的限制，让AI能像专家一样在不同领域评估优劣，并将海量非结构化经验数据转化为有效的学习信号。通 用验证器正是为此而生，它被认为可能引发强化学习的下一次范式革新。 今天，就用一篇文章了解当下大语言模型界最重要 ...

Core Viewpoint - OpenAI is set to launch the highly anticipated GPT-5, with multiple versions aimed at different applications and devices, despite concerns about its technological breakthroughs and commercial value [2][10]. Group 1: Product Launch - OpenAI will hold a live event to unveil GPT-5, with indications from executives and social media posts confirming its imminent release [2][4][6]. - GPT-5 will be available in three versions: standard, mini, and nano, each tailored for specific use cases and device types [8]. Group 2: Technical Specifications - The standard version of GPT-5 will serve as the main model for ChatGPT and API, integrating multimodal capabilities and reasoning abilities [9]. - The mini version is designed for cost-effectiveness and quick responses, while the nano version targets local inference and embedded device applications [9]. - Early experiences on the OpenRouter platform suggest that Horizon Alpha and Horizon Beta may correspond to the nano and mini versions, respectively, with Horizon Alpha featuring a context capacity of 256K tokens and a generation speed of 130-150 tokens per second [9]. Group 3: Commercial Focus - Reports indicate that GPT-5's development has shifted from seeking groundbreaking technological advancements to emphasizing practical value and commercial returns, with improvements in programming and mathematical capabilities as key selling points [10]. - A new reinforcement learning technique called "universal verifier" will be introduced to enhance the accuracy of model responses [10]. Group 4: Market Performance - OpenAI has experienced significant user growth, with ChatGPT's weekly active users reaching 700 million, a fourfold increase year-over-year, and daily message volume surpassing 3 billion [11]. - The number of paid commercial users surged from 3 million in June to 5 million, reflecting a 66% increase, indicating strong acceptance in the enterprise market [11]. - OpenAI's annualized revenue has reached $12 billion, a substantial increase compared to approximately $4 billion in 2024 [11].

Core Viewpoint - The introduction of the "Universal Validator" technology in GPT-5 is seen as a potential "secret weapon" for OpenAI to gain a competitive edge in the AI market [2][3]. Group 1: Technology Overview - The "Universal Validator" employs a "prover-verifier game" mechanism, where one AI model acts as a verifier to assess the answers generated by another prover model, enhancing output quality through internal competition [3][4]. - This technology aims to address the challenges of verifying answers in subjective fields like creative writing and complex mathematical proofs, which have been difficult for reinforcement learning methods [3][6]. - The framework includes roles such as a reliable prover, a deceptive prover, and a small verifier, which work together to improve the model's ability to distinguish between correct and incorrect solutions [6][7]. Group 2: Historical Context - The technology is considered a legacy of OpenAI's former "Super Alignment" team, which was focused on controlling future superintelligent AI, although the team was disbanded after key members left [10]. - Despite the team's dissolution, the technology has been integrated into OpenAI's core product development, addressing alignment and reliability issues in current models [10]. Group 3: Market Implications - The advancements brought by the "Universal Validator" are directly linked to the anticipated performance of GPT-5, with expectations heightened by statements from OpenAI's CEO regarding the model's superior capabilities [11]. - Competitors like xAI and Google are also investing heavily in reinforcement learning, making the "Universal Validator" a crucial asset for OpenAI to maintain its lead in the intensifying AI race [11]. Group 4: Challenges and Opportunities - The "Universal Validator" is noted for its versatility, improving model performance in both easily verifiable tasks and more subjective areas, indicating a shift in AI capabilities [14]. - However, the development of GPT-5 faces significant challenges, including a scarcity of high-quality training data and diminishing returns from large-scale pre-training, which could impact the model's expected breakthroughs [14].
