A mere two years ago, distinguishing between human-made and AI-generated imagery was a straightforward task. Early image models struggled with basic tasks, famously failing to create a simple Mexican restaurant menu without inventing peculiar culinary items such as “enchuita,” “churiros,” “burrto,” and “margartas.”
Today, the landscape has dramatically shifted. When prompted for a Mexican food menu, the new ChatGPT Images 2.0 model generates content so polished it could be immediately implemented in a restaurant without customers detecting any discrepancies. (Though, a ceviche priced at $13.50 might still prompt me to question the quality of the ingredients).
This represents a stark contrast to outputs from previous iterations, such as those generated by DALL-E 3 two years ago—a period when ChatGPT had not yet incorporated image generation capabilities.
Historically, AI image generators faced significant challenges with accurate text rendering, primarily due to their reliance on diffusion models. These models operate by reconstructing images from noise, a process that inherently struggled with the precise placement and formation of text.
As Asmelash Teka Hadgu, founder and CEO of Lesan AI, explained to TechCrunch in 2024, “The diffusion models […] are reconstructing a given input. We can assume writings on an image are a very, very tiny part, so the image generator learns the patterns that cover more of these pixels.” This inherent limitation meant that text, being a minute detail, was often overlooked in favor of broader image patterns.
In response to these limitations, researchers have since explored alternative image generation mechanisms, including autoregressive models. These models function more akin to large language models (LLMs), making predictions about what an image should depict as they construct it.
Despite these advancements, OpenAI chose not to disclose the specific model architecture powering ChatGPT Images 2.0 during a recent press briefing.
However, the company did highlight the new model's "thinking capabilities." These enhancements enable Images 2.0 to search the web, generate multiple images from a single prompt, and self-correct its creations. Such functionalities empower the model to produce diverse marketing assets in various sizes and even complex multi-paneled comic strips.
OpenAI further notes that Images 2.0 boasts a superior understanding of non-Latin text rendering, supporting languages like Japanese, Korean, Hindi, and Bengali. A key limitation, however, is the model’s knowledge cutoff in December 2025, which could affect the accuracy of generations involving very recent news or developments.
In a press release, OpenAI stated, “Images 2.0 brings an unprecedented level of specificity and fidelity to image creation. It can not only conceptualize more sophisticated images, but it actually brings that vision to life effectively, able to follow instructions, preserve requested details, and render the fine-grained elements that often break image models: small text, iconography, UI elements, dense compositions, and subtle stylistic constraints, all at up to 2K resolution.”
While these advanced capabilities mean that image generation is not as instantaneous as a typical ChatGPT text query, even complex tasks like creating a multi-paneled comic strip can be completed within just a few minutes.
ChatGPT and Codex users will gain access to Images 2.0 starting Tuesday, with paid subscribers benefiting from the ability to generate more advanced outputs. OpenAI also plans to release the gpt-image-2 API, with pricing structured according to the quality and resolution of the generated content.
