It’ll be hard to judge this for ourselves, though, as Google isn’t making the Imagen model available to the public. Google’s DrawBench benchmark compares the output of Imagen to rival text-to-image systems like OpenAI’s DALL-E 2. As shown in the graphs below, Google found that humans generally preferred the output from Imagen to that of rivals’. Google, though, claims that Imagen produces consistently better images than DALL-E 2, based on a new benchmark it created for this project named DrawBench.ĭrawBench isn’t a particularly complex metric: it’s essentially a list of some 200 text prompts that Google’s team fed into Imagen and other text-to-image generators, with the output from each program then judged by human raters. It highlights, among other things, the tendency of the system to misunderstand prompts, and struggle with both text and faces.) (For more on the trouble spots for text-to-image systems, check out this interesting Twitter thread that dives into problems with DALL-E. Often, images generated by text-to-image models look unfinished, smeared, or blurry - problems we’ve seen with pictures generated by OpenAI’s DALL-E program. Remember: Google is only showing off the very best images You type what you want to see and the program generates it. In each case, the text at the bottom of the image was the prompt fed into the program, and the picture above, the output. There’s some generated by Imagen above, and even more below ( you can see more examples at Google’s dedicated landing page). The best way to understand the amazing capability of these models is to simply look over some of the images they can generate. Yesterday, though, Google announced its own take on the genre, Imagen, and it just unseated DALL-E in the quality of its output.
To date, the leader in the field has been DALL-E, a program created by commercial AI lab OpenAI (and updated just back in April). They can match a range of styles, from oil paintings to CGI renders and even photographs, and - though it sounds cliched - in many ways the only limit is your imagination.
Feed these programs any text you like and they’ll generate remarkably accurate pictures that match that description.
