Abstract

A new AI image generation model, widely referred to as "GPT Image 2," has been leaked and is demonstrating significant advancements over predecessors like DALL-E 3 and even Google's Nano Banana Pro. It excels in four key areas: text rendering, prompt adherence, photorealism, and world knowledge. The model can generate highly accurate text in multiple languages, including complex Chinese characters, making it capable of producing convincing fake documents, UI screenshots, and product labels. This capability also raises concerns about the reliability of using screenshots as evidence. The model is currently in A/B testing, with a full release expected around May 2026 when DALL-E services are officially retired. It is accessible for testing on the LM Arena platform. The article includes several prompt templates optimized for the model, such as generating realistic app screenshots, product photos with detailed labels, and street scenes with accurate signage. This advancement is reshaping creative workflows but also accelerating the displacement of some traditional design roles.

Is your impression of text-to-image still stuck on Nano Banana?

But kid, times have changed again.

In early April, three anonymous image models, codenamed maskingtape-alpha, packingtape-alpha, and gaffertape-alpha, appeared on the LM Arena evaluation platform. They disappeared a few hours later.

OpenAI has not officially announced this model yet, but based on the metadata returned by the API and user-side testing records, it has already gained a widely accepted name: GPT Image 2.

Screenshots Can No Longer Be Used as Evidence

Over the past few years, one of the most obvious weaknesses of AI image generation models has been text within images. In the DALL-E 3 era, if you asked it to write "Hello" in an image, it might output "Hellp" or even "Hl10", with letters tilting drunkenly. GPT Image 1 improved a lot, handling simple English labels. By GPT Image 1.5, its accuracy in rendering English text was close to 95%, but it still had significant flaws with non-Latin scripts like Chinese, Japanese, and Korean.

But the leaked sample images from GPT Image 2 have changed this impression.

The text in the images is exactly what it should be. Chinese characters are clear, with accurate glyphs and complete strokes. Someone tested generating an ID card-style image, where the name, address, and ID number were all rendered correctly, with neat formatting, looking at first glance like a photo of a real document.

This is good news. The improvement in text rendering means generating infographics, posters, product packaging, and complex charts becomes more reliable.

But there's always another side to the coin. A model that can generate photo-realistic ID-style images and precisely render UI screenshots naturally makes "screenshots can be used as evidence" increasingly questionable.

By comparison, this is also a core difference between the GPT Image series and other models. Midjourney still has no progress in text rendering, and the Stable Diffusion series also has this old problem. According to the leaked Arena test results, GPT Image 2 surpassed Midjourney in four dimensions: text rendering, instruction following, photorealism, and world knowledge. Midjourney's advantages are mainly retained in artistic style and aesthetic control.

Does It Really Know What the World Looks Like?

A tester asked the model to generate a hypothetical GPT-8 product pricing page. The resulting image had a layout that was indeed in the style of the OpenAI website, with button placement and font choices resembling those from a real interface, and the hierarchical logic of the price table was correct.

GPT Image 2 can generate images extremely similar to real software interfaces, including browser windows, mobile app interfaces, and data visualization charts, with a level of fidelity unmatched by the previous generation.

This will lead to some very interesting practical uses. When designers are creating product prototypes, they don't need to open Figma first and draw a bunch of wireframes; they can directly describe the desired interface in text, and the output is a reference image that can be used for team discussions. When creating investor decks, they can show a "product screenshot" without waiting for an engineer to write code. When writing documentation, example interface images for illustration can be generated directly, without having to think about where to find screenshots for a blank page.

Image Generation Is No Longer Just "Image Generation"

OpenAI has already announced that DALL-E 2 and DALL-E 3 will officially cease service on May 12, 2026. Azure OpenAI's DALL-E 3 was retired early in February.

DALL-E was the first place many people encountered AI image generation, from those blurry early works to today, in just a few short years.

Meanwhile, Google, which had just established its industry position with Nano Banana Pro in early 2026, might feel the pressure. Early test reports indicate that GPT Image 2 simultaneously surpasses Nano Banana Pro in three dimensions: realism, text rendering, and world knowledge. This kind of triple win is not common.

For creators, the feeling is complex. Illustrators, graphic designers, and photographers are not facing this topic for the first time. Since the release of GPT Image 1, the number of freelance graphic design positions has decreased by about 18%. AI has indeed replaced the decision to "hire someone to do this" in certain scenarios, but it is also creating new ways of working, allowing one person to do more.

The evolution speed of image generation models no longer leaves much time for adaptation. It was only a few months from GPT Image 1's launch to version 1.5. And from 1.5 to 2, it's only been about half a year. Each generation solves the core shortcomings of the previous one while opening up new possibilities.

GPT Image 2 is currently still in the A/B testing phase, with some ChatGPT users randomly gaining access. The official release window is widely predicted to be around May, coinciding with the retirement of DALL-E. If you want to experience it early, you can currently try your luck on the LM Arena evaluation platform.

Unitree Passes the Hearing, Hangzhou Reaps the Rewards

Unitree Technology, a leading company in Hangzhou's tech scene known as one of the "Hangzhou Six Dragons," has officially passed the review for listing on the Shanghai Stock Exchange's STAR Market (科创板). It plans to raise 4.202 billion yuan for the research and development of intelligent robot models and robot hardware. This milestone will make Unitree the "first humanoid robotics stock." Founded in 2016 by Wang Xingxing, the company started humbly in a small office in Hangzhou's Binjiang district. Initially, the robotics sector was not viewed favorably by the market, with Unitree's products often labeled as "toys" and struggling to secure funding. At its most critical point, with only around 100,000 yuan left, Wang stopped his own salary to keep the company afloat. A crucial turning point came in 2018 when Hangzhou's state-owned capital system provided timely support. A financial platform under the city's state-owned assets completed due diligence in three days and granted a 20-million-yuan loan within a week. This "patient capital" infusion stabilized Unitree, enabling its transition from prototype development to mass production and commercial viability. Subsequently, Hangzhou Capital, through its two major 100-billion-yuan mother funds—the Hangzhou Science and Technology Innovation Fund and the Hangzhou Innovation Fund—participated in four of Unitree's financing rounds (B2, B3, C, and C+). This continuous backing helped the company grow, attract top-tier industrial investors like China Mobile, Tencent, Alibaba, and Geely, and solidify its position as a global leader in legged robotics. By 2025, Unitree achieved significant scale, with revenue reaching 16.99 billion yuan, net profit of 5.91 billion yuan, global leadership in humanoid robot shipments, and over 33,000 quadruped robots sold worldwide. Unitree's journey exemplifies Hangzhou's strategy of nurturing hard-tech startups from "seedlings" to industry leaders. Beyond Unitree, Hangzhou's capital ecosystem has supported other "Six Dragons" like Cloudwalk, BrainCo, and DeepSeek. The city has established a 500-billion-yuan "3+N" industrial fund cluster and specialized early-stage funds like the "Runmiao Fund" with a 20-year term to fill funding gaps for very early-stage projects. This robust "capital + talent" model, coupled with an influx of over 430,000 young professionals in 2025 alone, has fostered a vibrant innovation ecosystem. Hangzhou is now home to 48 unicorns and 413 potential unicorns, building comprehensive industrial chains in AI, robotics, brain-computer interfaces, and more. As Hangzhou experiences a wave of IPOs, it is solidifying its reputation as an ideal city for entrepreneurs.

Are Rising U.S. Stocks Getting More Dangerous? Goldman Sachs: Downside Protection Mechanisms Have Almost Failed

The US stock market rally is showing signs of becoming increasingly precarious as key downside protection mechanisms fail, according to Goldman Sachs. Derivatives strategist Brian Garrett notes that the S&P 500 options volatility skew has plunged to an 18-month low, indicating the market now prices an 8% probability for both a 10% drop and a 10% rise—a sign of "skew failure." Concurrently, Goldman's Panic Index hit a two-year low, reflecting minimal demand for tail-risk hedging. This complacency emerges amid a relentless market surge, with the S&P 500 setting new records frequently in 2024. Garrett highlights three major concerns: extreme concentration in the top ten stocks (40% of index weight), heavy reliance on AI-themed performance, and a price pattern eerily similar to the 1998-1999 period. Despite pervasive media pessimism, this fear is absent in options pricing. Downside hedge costs are historically low. Goldman suggests tactical trades: buying RSP outperformance options versus the SPX for a broadening rally, purchasing VIX calls for protection, and going long on Bitcoin ETF volatility. Hedge funds have been net buyers for two weeks, with sector rotation into financials and out of industrials. Notably, the global single-stock leveraged/ inverse ETF AUM has doubled to over $60 billion in two months, underscoring growing speculative activity.

DAT Failure? Listed Companies Betting on HYPE Floating Profit of $12.5 Billion

Several public companies that adopted a "HYPE Treasury" strategy—holding significant reserves of the HYPE token from the Hyperliquid ecosystem—have achieved substantial paper gains, collectively exceeding $1.25 billion. This contrasts with the reported struggles of MicroStrategy's flagship BTC treasury strategy. The article profiles three such HYPE-focused treasury companies: 1. **Hyperliquid Strategies Inc. (PURR):** The largest holder, with approximately 22.3 million HYPE tokens valued at ~$1.636 billion, resulting in an unrealized gain of ~$1.22 billion. It has fully transitioned from a biotech firm to a dedicated crypto treasury, adding staking and validator operations to enhance returns. 2. **Hyperion DeFi (HYPD):** Holds around 2 million HYPE tokens (~$147 million value) with a gain of ~$49.4 million. It is deeply integrated into the Hyperliquid ecosystem, running a major validator node and building DeFi products for additional yield. 3. **Lion Group Holding (LGHL):** A smaller holder with ~194,000 HYPE tokens (~$14.14 million value), maintaining a long-term commitment to the token. The success of these HYPE treasuries is attributed not only to the token's significant price appreciation but also to active on-chain participation through staking, validation, and ecosystem integrations, creating a compounding "flywheel" effect. The article posits that while MicroStrategy's BTC strategy faces challenges, HYPE treasuries may offer a more sustainable model through deeper protocol engagement, with potential for further growth if HYPE's price rises as predicted by some analysts.
