DALL·E 2
DALL·E 2 és un sistema d'IA que pot crear imatges i art realistes a partir d'una descripció en llenguatge natural.
DALL·E 2 can create original, realistic images and art from a text description. It can combine concepts, attributes, and styles.
DALL·E 2 pot crear imatges i art originals i realistes a partir d'una descripció de text. Pot combinar conceptes, atributs i estils.
El gener de 2021, OpenAI va presentar DALL·E. Un any després, el nostre sistema més nou, DALL·E 2, genera imatges més realistes i precises amb una resolució 4 vegades superior.
DALL·E 2 is preferred over DALL·E 1 when evaluators compared each model.

A focus on safety
DALL·E 2 began as a research project and is now available in beta. Safety mitigations we have developed and continue to improve upon include:
Preventing harmful generations
We’ve limited the ability for DALL·E 2 to generate violent, hate, or adult images. By removing the most explicit content from the training data, we minimized DALL·E 2’s exposure to these concepts. We also used advanced techniques to prevent photorealistic generations of real individuals’ faces, including those of public figures.

Curbing misuse
Our content policy does not allow users to generate violent, adult, or political content, among other categories. We won’t generate images if our filters identify text prompts and image uploads that may violate our policies. We also have automated and human monitoring systems to guard against misuse.

Phased deployment based on learning
Learning from real-world use is an important part of developing and deploying AI responsibly. We began by previewing DALL·E 2 to a limited number of trusted users. As we learned more about the technology’s capabilities and limitations, and gained confidence in our safety systems, we slowly added more users and made DALL·E available in beta in July 2022.

Esperem que DALL·E 2 permeti a les persones expressar-se de manera creativa.
DALL·E 2 també ens ajuda a entendre com els sistemes d'IA avançats veuen i entenen el nostre món, cosa clau per a la nostra missió de crear IA que beneficiï la humanitat.
