The German Government is temporarily reducing value added tax (VAT) from July 1st until December 31st this year. The German tax rates will change from 19% to 16% (regular VAT rate) and from 7% to 5% (reduced VAT rate). It is the aim of the German Government that retailers pass on the reduction to customers through lowered prices.

While this is not a required action for your published apps on the Amazon Appstore, you may choose to update the List Price of your apps and in-app purchasable items sold in Germany for the duration of the VAT reduction.

Before you apply any changes to the List Price for your apps and in-app purchasable items sold in Germany, please take note of the following:

  • Changing the List Price for the “” Marketplace will also impact the calculation of Royalties for apps sold in Austria (AT), where at the moment there is no VAT reduction.
  • If you plan to update the List Price for a subscription, please make sure to carefully read the documentation on how to Update Subscription Price on the Amazon Appstore Developer Portal. The system behavior for a given subscriber depends on the price that the subscriber is currently paying.

If you would like to lower the list price for your apps, you can follow the steps below on the Amazon Developer Console:

  • Go to “App List” and select the app where you would like to lower the list price
  • For Paid Apps, go to “Availability and Pricing” and edit pricing for the “” marketplace
  • For editing In-App Items, go to the “In-App Items” tab. For each In-App Item, edit the list pricing for the “” marketplace.

If you have any additional questions, please contact Amazon Appstore Developer Support.

The Alexa Prize SocialBot Grand Challenge is now in its third year.  And for a third time participating student teams have made exciting advances in the state-of-the-art of conversational AI.  With gratitude for the efforts of all the teams this year, I am delighted to announce the five teams that are advancing to the Alexa Prize Finals.

The three socialbots with the highest average customer ratings during the semifinal period have automatically advanced: Alquist from the Czech Technical University in Prague, Emora from Emory University, and Gunrock from the University of California, Davis. We also advanced two wildcard teams this year based on evaluation criteria that included ratings from Alexa customers, depth and breadth of topics covered, appropriateness and accuracy of responses, and scientific merit as determined by the content of their technical papers: Chirpy Cardinal from Stanford University and Athena from the University of California, Santa Cruz.

In July 2019, ten university teams were selected from applications submitted by labs around the world to compete for the Alexa Prize. Since then, teams have been working tirelessly to delight customers with engaging and coherent conversations on a variety of popular topics. Now, the advancing five teams will compete for the Grand Prize.  If they have a composite score of 4.0 or higher, and at least two-thirds of their Socialbot’s conversations with interactors last for 20 minutes, they will win a $1 million research grant for their University.

Congratulations to Alquist, Athena, Chirpy Cardinal, Emora, and Gunrock!

On behalf of the entire Amazon Alexa organization, I want to thank all of the Alexa Prize teams for their creativity, passion, and contributions to both AI science and to delighting Alexa customers. We will be publishing the teams’ technical papers in a special-edition Alexa Prize Journal later this summer, enabling all teams to share their innovative ideas with the scientific community.

In the meantime, please continue to support our finalists by chatting with their socialbots, it’s as easy as saying “Alexa, let’s chat” to your Alexa-enabled device. You can also follow #AlexaPrize on Twitter and bookmark our website for further updates.

This past September, 10 university teams, from schools around the world, officially began their journey with the Alexa Prize Socialbot Grand Challenge 3. Teams spent part of their summer attending an intensive boot camp to learn what it means to be customer obsessed and how to integrate their ideas into the Alexa Prize infrastructure. Now ready to compete, teams have built an AI (called a socialbot), at scale, capable of conversing coherently and engagingly with humans for 20 minutes. Their socialbots should be able to discuss popular topics and news events such as entertainment, fashion, politics, sports, and technology.

Even as innovators create AI that can drive cars, play board games, and diagnose diseases, the seemingly intuitive task of everyday social conversation remains an elusive goal. Undaunted, the student teams have geared up to tackle the challenge. As they build their socialbots, they will encounter esoteric problems like context modeling and dialog planning as well as exoteric problems like user experience and conversational engagement. The Alexa Prize provides a unique opportunity for industry and academia to come together to address these challenges.

We invite you to join the students on their journey and help them along the way. You can interact with their socialbots simply by saying, “Alexa, let’s chat” on any Alexa-enabled device in the US-English marketplace. You will be connected to one of the 10 socialbots at random. Chat about your favorite topics, say “Stop” when you are done, and share your feedback.

It is still early days in this pioneering journey, and we know the teams will appreciate your help and patience as they learn, iterate, and build new interactive conversational experiences. The socialbots will improve quickly based on your use and feedback. We hope you’ll enjoy interacting with them.

The student teams are working hard, having fun, and well on their way to making history. We look forward to having you join the Alexa Prize community to support them along the way.
