Abstract

近日，LM Arena评测平台短暂出现了三个匿名图像模型，据推测为OpenAI尚未正式发布的GPT Image 2。该模型在文字渲染、指令跟随、真实感和世界知识等方面表现突出，尤其在多语言文字（包括中文）的生成上准确率大幅提升，能生成高度逼真的证件、界面和产品标签图像。这一进步使得截图作为证据的可信度受到挑战，但也为设计、产品原型制作及内容配图等场景带来便利。与此同时，GPT Image 2在多项测试中表现优于Google的Nano Banana Pro及Midjourney等模型。目前该模型仍处于A/B测试阶段，预计将在5月随DALL-E系列服务退役后正式发布。用户可尝试在LM Arena平台体验，并参考社区推荐提示词生成高质量图像。

你对文生图的印象还停留在 Nano Banana 吗?

可是孩子,时代又变了。

4 月初,LM Arena 评测平台上出现了三个匿名图像模型,代号分别是 maskingtape-alpha、packingtape-alpha、gaffertape-alpha。几小时后它们消失了。

OpenAI 官方还没有正式宣布这个模型,但根据 API 返回的元数据和用户侧的测试记录,它已经有了一个被广泛接受的名字:GPT Image 2。

截图不能再当证据了

过去几年,AI 生图模型最明显的短板之一就是图片里的文字。DALL-E 3 时代,你让它在图里写「Hello」,出来的可能是「Hellp」甚至「Hl10」,字母像喝醉了一样东倒西歪。GPT Image 1 好了很多,能处理简单的英文标签。到 GPT Image 1.5 ,其对英文文字的渲染准确率已经接近 95%,但在中文、日文、韩文等非拉丁字母体系上仍有明显缺陷。

而 GPT Image 2 的泄露样图改变了这个印象。

@akokoi1 https://x.com/akokoi1/status/2044789531615056175

图片里的文字,该是什么就是什么。中文清晰,字形准确,笔画完整。有人测试生成一张身份证样式的图片,姓名、地址、证件号码全部正确渲染,排版规整,初看像是真实文件的照片。

这是个好消息。文字渲染的进步,意味着生成信息图、海报、产品包装、排版复杂的图表,都变得更可靠了。

但硬币总有另一面。一个能生成以假乱真的证件样式图、精确渲染 UI 截图的模型,自然也让「截图可以作为证据」这件事变得越来越可疑。

对比来看,这也是 GPT Image 系列和其他模型的核心差异所在。Midjourney 至今在文字渲染上毫无建树,Stable Diffusion 系列也是老问题。根据泄露的 Arena 测试结果,GPT Image 2 在文字渲染、指令跟随、照片真实感和世界知识四个维度上均超过 Midjourney,后者的优势主要保留在艺术风格和美学控制上。

它真的知道这个世界长什么样吗

有测试者让模型生成一个假想的 GPT-8 产品定价页面,结果出来的图,排版确实是 OpenAI 官网的风格,按钮位置和字体选用像是从真实界面截取的,价格表格的层级逻辑也是对的。

GPT Image 2 能生成与真实软件界面极为相似的图像,包括浏览器窗口、移动端应用界面、数据可视化图表,保真度是上一代产品无法比拟的。

这将带来一些很有意思的实际用途。设计师在做产品原型的时候,不需要先打开 Figma 画一堆框架,直接用文字描述想要的界面,出来的就是一张可以用来和团队讨论的参考图。做投资人 Deck 时,不需要等工程师写代码就能展示一个「产品截图」。写文档的时候,用来配图的示例界面可以直接生成,不用对着空白页面想截图从哪里找。

生图这件事,已经不只是「生图」了

OpenAI 已经宣布 DALL-E 2 和 DALL-E 3 将于 2026 年 5 月 12 日正式停止服务。Azure OpenAI 的 DALL-E 3 已经在 2 月提前退役了。

DALL-E 是很多人第一次接触 AI 生图的地方,从那些模糊的早期作品到今天,才短短几年。

与此同时,2026 年初刚刚凭借 Nano Banana Pro 确立行业地位的 Google,或许将感受到压力。早期测试报告显示,GPT Image 2 在真实感、文字渲染和世界知识三个维度上同时超越了 Nano Banana Pro,这种三连胜并不常见。

对于创作者来说,感受是复杂的。插图师、平面设计师、摄影师,已经不是第一次面对这个话题了。自 GPT Image 1 发布以来,自由职业平面设计职位数量下降了约 18%。AI 在某些场景下确实取代了「我要雇一个人做这件事」的决策,但它也在创造新的工作方式,让一个人能做的事变多了。

生图模型的进化速度,已经不再给人留出太多适应时间了。GPT Image 1 从上线到 1.5,不过几个月。1.5 到 2,大概也就半年。每一代都在解决上一代的核心短板,同时打开新的可能性。

GPT Image 2 现在还处于 A/B 测试阶段,部分 ChatGPT 用户已经随机获得了访问权限。正式发布的时间窗口,普遍预测就在 5 月 DALL-E 退役前后。想要提前体验的话,目前可以在 LM Arena 评测平台碰碰运气。

No Sales Team, $20 Million in Revenue: How Did AI Employee Viktor Win Over 30,000 Companies?

The AI employee Viktor, developed by a team with DeepMind background, has achieved $20 million in annual revenue without a traditional sales team, serving over 30,000 companies. Its core innovation lies in positioning itself as a "Tier 3 AI Coworker" capable of "end-to-end execution and delivery of results," moving beyond the "draft and wait for human completion" model of typical AI assistants. Users can simply mention Viktor in Slack or Microsoft Teams using natural language commands, and it autonomously performs tasks like pulling sales data from a CRM, generating reports, or even cross-tool operations like creating board meeting PPTs by aggregating data from six different sources. Key to its growth is a pure Product-Led Growth (PLG) model, eliminating complex implementation cycles and per-seat licensing. Instead, it charges based on task credits or consumption, lowering the trial barrier with a $100 free credit offer and no credit card required. This enabled viral, bottom-up adoption within organizations. Viktor's interaction paradigm removes the barrier of prompt engineering, allowing non-technical employees to delegate complex workflows seamlessly. It also features proactive, automated task execution (e.g., overnight bookkeeping, scheduled reports) based on triggers, effectively embedding AI as an automated "process layer" within business operations. However, its expansion into Microsoft Teams—a platform with 320 million users—highlights challenges. Large enterprises require stringent IT compliance, security reviews (e.g., SOC 2), and governance, potentially hindering the frictionless, user-driven adoption that succeeded in Slack. Additionally, the "black box" nature of its autonomous decision-making raises concerns about operational risks, data integrity, and the need for robust audit logs and permission controls. Balancing efficiency gains with security and trust remains a critical hurdle for Viktor and similar AI agents aiming to become core enterprise infrastructure.

Interview with CoreWeave Co-founders: AI Demand Seems to 'Intensify' Every Day

An Interview with CoreWeave Executives: AI Demand Seems to 'Intensify' Every Day In an interview, CoreWeave executives highlight a structural shift in AI infrastructure demand. While GPU availability remains crucial, the primary bottlenecks are evolving to include powered data center shells, skilled labor (like electricians), and complex supply chain execution. They note that AI demand, particularly for agentic AI and reasoning models, continues to intensify daily, accelerating since Q1 2024. This demand is driving a need for more balanced infrastructure. CoreWeave is redesigning data centers to allocate more space for storage and CPUs alongside GPUs, with significant interest in Nvidia's upcoming Vera CPUs. The company, serving top AI labs and hyperscalers, emphasizes its client-driven model, building precisely to customer specifications. CoreWeave attributes its competitive edge to proven execution, performance, and a mature platform for AI deployment. Pricing is structured to pass component cost increases (e.g., for HBM memory) to customers, protecting margins. Looking ahead, they anticipate Vera Rubin platform deployments to begin meaningfully in late 2025, with a major ramp throughout 2027, mirroring the Blackwell (GB) series rollout pattern. The competition is shifting from merely acquiring chips to holistic engineering and delivery capability.

Manus Buyback Plan Emerges: Chinese Investors Plan to Repurchase Equity with $2 Billion, Path to Hong Kong IPO Becomes Clearer

According to a report by The Information, early Chinese investors of Manus, including Tencent, Sequoia Capital China, and ZhenFund, are planning to repurchase the company from Meta for $2 billion—the same price Meta paid in its acquisition last December. This move is a direct response to the Chinese government's prohibition of the foreign acquisition in April. As part of the repurchase plan, Manus is considering establishing a Sino-foreign joint venture within China. This structure is seen as a way to ensure regulatory compliance for its Chinese investors and to pave the way for a future IPO in Hong Kong. Notably, U.S. investor Benchmark will not participate in the buyback, which will concentrate ownership even more among Chinese capital. Since its acquisition by Meta, Manus's business has grown rapidly, with its annualized revenue run rate reportedly increasing four-to-fivefold to $400-$500 million in roughly six months. This strong growth underpins the investors' willingness to repurchase at the original price. Financially, the forced unwinding of the deal may benefit the early investors, allowing them to regain equity at a cost far below the company's current implied valuation, with the added prospect of an independent future listing. However, specific terms of the repurchase, including funding proportions and the joint venture's equity structure, are still under negotiation. This "repurchase-joint venture-Hong Kong IPO" approach could serve as a reference model for other Chinese AI startups navigating cross-border M&A regulations.

STRC Loses Peg by 11%, Can Strategy's Perpetual Motion Machine Keep Running?

The article discusses the significant and concerning depegging of MicroStrategy's (MSTR) preferred stock, STRC. Designed to trade near its $100 target par value, STRC has recently fallen sharply, reaching a low of $83.26 and closing at $88.59, representing an over 11% discount. STRC is a core component of MicroStrategy's financial strategy. As a perpetual preferred stock, it allows the company to raise capital through an "at-the-market" (ATM) issuance program without diluting common shareholders (MSTR). This capital is primarily used to purchase Bitcoin, creating a "capital flywheel": issuing STRC → raising cash → buying BTC → increasing net assets → supporting STRC's value. The flywheel's operation depends on STRC maintaining its $100 price. To enforce this, MicroStrategy employs a dynamic dividend mechanism, recently raising the rate to 11.5% and increasing payout frequency. However, this has failed to halt the depegging, indicating market concerns extend beyond yield. Analysts cite two main reasons. First, technical factors like forced liquidations from leveraged arbitrage trades may have exacerbated the sell-off. Second, and more fundamentally, is waning confidence in MicroStrategy's financial resilience. A JPMorgan report highlighted the company's limited cash relative to its ~$1.7 billion annual dividend obligation, raising liquidity concerns. While MicroStrategy counters that its massive Bitcoin holdings provide decades of coverage, this argument relies on the potential need to sell BTC—a departure from its long-standing "never sell" narrative. The company's recent sale of a small amount of Bitcoin for "testing," despite being framed as minor, has intensified these fears. The persistent depegging threatens to cripple MicroStrategy's primary funding channel. If STRC remains discounted, the company's ability to fund further Bitcoin purchases weakens. Should cash reserves dwindle while financing is constrained, the market may increasingly price in the risk of MicroStrategy becoming a forced seller of Bitcoin to meet obligations. This shift from a major marginal buyer to a potential seller could pose significant downside risk to the broader Bitcoin market.

Altcoins Face Deepest Spot Sell Pressure Since 2020, CryptoQuant Data Shows

Altcoins are enduring one of their most severe periods of spot-market selling pressure since 2020, according to CryptoQuant data, with a cumulative buy/sell volume gap of roughly $209 billion. This reflects weak retail demand, a rotation into safer assets like Bitcoin, Ethereum, and stablecoin yield products, and broad investor caution. While such extreme selling can set the stage for a contrarian opportunity by showing one-sided positioning, the data does not yet signal an immediate reversal or altcoin season. The market remains in a defensive state, lacking the sustained spot accumulation and broad sector improvement needed for a confirmed bullish turn.
