ChatGPTの新画像生成モデル「Images 2.0」、テキスト生成能力が驚くほど高い

It used to be easy enough to distinguish between human-made and AI-generated imagery — just two years ago, you couldn’t use image models to create a menu for a Mexican restaurant without inventing new culinary delights like “enchuita,” “churiros,” “burrto,” and “margartas.”

Now, when I ask the brand new ChatGPT Images 2.0 model for a menu of Mexican food, it creates something that could immediately be used in a restaurant without customers noticing that something’s off. (However, ceviche priced at $13.50 might make me question the quality of the fish.)

For comparison, here’s the result I got from DALL-E 3 two years ago (at the time, ChatGPT did not generate images):

AI image generators have historically struggled to spell because they generally used diffusion models, which work by reconstructing images from noise.

“The diffusion models […] are reconstructing a given input,” Asmelash Teka Hadgu, founder and CEO of Lesan AI, told TechCrunch in 2024. “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.”

Researchers have since explored other mechanisms for image generation, like autoregressive models, which make predictions about what an image should look like and function more like an LLM.

Unfortunately, OpenAI declined to answer a question in a press briefing this week about what kind of model is powering ChatGPT Images 2.0.

The company did, however, explain that the new model has “thinking capabilities,” which give it the ability to search the web, make multiple images from one prompt, and double-check its creations — this allows Images 2.0 to create marketing assets in various sizes, as well as multi-paneled comic strips.

OpenAI also says that Images has a stronger understanding of non-Latin text rendering in languages like Japanese, Korean, Hindi, and Bengali. The model’s knowledge cuts off in December 2025, which could impact how accurately it can generate certain prompts involving recent news.

“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,” OpenAI said in a press release.

These capabilities mean that image generation isn’t as rapid as typing a question to ChatGPT, but generating something complex like a multi-paneled comic still takes just a few minutes.

All ChatGPT and Codex users will be able to access Images 2.0 starting Tuesday; paid users will be able to generate more advanced outputs. The company will also make the gpt-image-2 API available, with pricing dependent on the quality and resolution of outputs.
