I was admitted as beta Tester by OpenAI on August 15, 2022. Here is my first image generated with the prompt cartoon of an elephant and a giraffe riding a bicycle on the beach. I posted it the same day on Facebook.

In the following days I generated more images and posted them as Image of the Day on Facebook. Here is a small gallery :

My first prompt became my favorite one to test new image generators when they became available. During your visit of posts about other images generators in the present knowledge section of the KI-Léierbud you will discover more images showing elephants and giraffes riding bicycles.

KI-Léierbud. For whom ?

Six generations from six cultures make music together in the band KI-LéierBeats.

KI-Léierbud: Learning Across Generations and Cultures

The KI-Léierbud project is designed for all generations and all cultures, promoting digital literacy, creativity, and collaboration through innovative, interactive learning experiences. It embraces the full human spectrum — from the wisdom of the past to the curiosity of the future.

To illustrate this spirit of inclusion, the musical group KI-LéierBeats brings together six musicians from different generations and cultural backgrounds:

  1. Arjun Rao – an Indian man born in 1930, representing the Silent Generation.
  2. Henrik Vogel – a European man born in 1948, from the Baby Boomer Generation.
  3. Layla Mansour – an Arab woman born in 1966, part of Generation X.
  4. Mei Lin – a Chinese woman born in 1984, belonging to the Millennial Generation.
  5. Sofia Morales – a Latin American woman born in 2002, representing Generation Z.
  6. Kofi Adeyemi – an African boy born in 2020, a member of Generation Alpha.

Together, they form a vibrant ensemble where six cultures and six generations meet through music — a universal language that reflects the inclusive vision of KI-Léierbud.

Six generations. Six cultures. One band – KI–LéierBeats.
