<p>We’re excited to announce the launch of our new feed algorithm, codenamed Sauron.</p>
<h2>What is Project Sauron?</h2>
<p>Project Sauron introduces a cutting-edge Two Tower retrieval model, a technique famously used by platforms like YouTube, Instagram, and Uber Eats. This state-of-the-art approach enables lightning-fast personalized retrieval of content from a database containing millions of records. In our context, this model helps us connect you with the best development content available.</p>
<h2>How Does It Work?</h2>
<p>The Two Tower model creates a new embedding space where both our posts and users coexist. This space allows us to calculate similarities between entities—posts and users—enabling us to recommend content and users that align with your interests. The magic lies in generating these embeddings offline, so in real-time, we only perform vector similarity computations using Redis. This process ensures incredibly fast feed delivery, happening within microseconds.</p>
<h2>Why Should You Care?</h2>
<p>During our testing phase, we noticed that users loved the new algorithm. We’ve seen a 11% increase in reads per user and a significant rise in new bookmarks.</p>
<h2>How Can You Help?</h2>
<p>To keep improving your feed, we encourage you to upvote and downvote posts. Your feedback directly influences your recommendations, making it easier for you to stay up-to-date with the latest and most relevant content.</p>
<p>We’re committed to helping you stay up to date, and with this new release, it’s easier than ever. Thank you for being a part of our community!</p>

Project Sauron is a new feed algorithm utilizing a cutting-edge Two Tower retrieval model, similar to those used by YouTube and Instagram, to deliver personalized content rapidly. By creating a shared embedding space for posts and users, the algorithm calculates similarities to recommend the most relevant content. Users have reported an 11% increase in reads per user and a spike in new bookmarks during the testing phase. User feedback through upvotes and downvotes helps refine these recommendations.

Project Sauron is Live! 👁️

<p>I wonder how many here realize why we picked Sauron as the codename 😬</p>


<p>The whole concept of determining my “calculated interests” and only presenting future posts that align with those interests in my feed is disheartening.  It would appear that we are driving for the bizarre situation of asking our semi-intelligent, not quite AI based personal voyeur to please show us some posts or even ads that are different than the derived interest base.  Hopefully there will be a functioning opt out option.</p>


<p>Will this ever go opensource or is it some simillar open source project?</p>
