FINALLY, the code is open source and it is now possible to understand why our posts are sh*t.

I will explain it to you step by step here. There is a fundamental difference compared to the past. Where the 2023 version, known as The Algorithm, was still full of manually programmed rules, the new version runs on Phoenix. A system based on Grok AI that understands what content is. Before, it only looked at likes.

1. THE BIG CHANGE🌎

The most important insight from the new xAI repository is that X has stopped using manual feature engineering.

• 2023 to 2025 Developers defined rules, for example if photo then plus 2 points.

• January 2026 A neural network, Grok based transformers, learns by itself what is engaging by looking at billions of interactions.

2. The formula

Even though the AI learns on its own, X guides the AI with a score formulaa: BE A HUNTER!🦁

• Reply - The absolute king. A reply weighs up to 13.5x to 27x heavier than a like.

• The reply multiplier - If you as the author reply to a reply under your post, and that person replies again, the value of your post skyrockets. Up to 75x in older models and still dominant in Phoenix.

• Retweet - Weighs roughly 20x heavier than a like. This spreads your content outside your own network.

• Profile click - About 12x a like. If someone clicks through to your profile after a tweet, it is a huge signal of interest. Who is this person.

• Bookmark - Very highly valued, around 10x. This tells the AI this is high quality content or reference material.

• Like - The base value, 1x. Necessary, but not enough on its own to go viral.

• Video or image- Content with media historically gets a 2x boost in initial visibility.
