1-3-12 Machiya, Arakawa-ku, Tokyo,
VoIP & Asterisk Lounge Special Event! 👏👏
This time, we will demonstrate how to create a video chat application using generative AI.
All you need to participate is a web browser, so anyone can join easily.
Support staff will be available, so hands-on participation is very welcome!
Who Should Attend
This event is for anyone interested in experiencing development using generative AI.
No need to set up a development environment, and no coding is required—feel free to join casually.
If you have never developed before, you can still fully enjoy the atmosphere just by watching.
If you have development experience, you can join the hands-on session and experience how easy it is.
This session focuses on experiencing the overall workflow rather than diving into technical details.
If you are already actively developing with generative AI, we encourage you to join as a support staff member.
