The 10 Commandments of the X Algorithm

Every rule below is derived directly from xai-org/x-algorithm source code — scoring formula, action indices, pipeline stages, and architecture. No speculation.

I
Thou shalt earn the favorite above all else
The published scoring formula weights favorite at 1.0× — the highest of any tracked signal in run_pipeline.py. Every content decision should first ask: will this make someone tap like? The content that earns a like and a reply is twice as powerful as content that earns only one.
FAV × 1.0 in run_pipeline.py
II
Thou shalt make people reply — it is the second law
Reply is weighted 0.5× — second highest in the formula. A post that generates 20 replies from followers sends a strong quality signal that accelerates Phoenix pickup. Reply velocity in the early window is the model's clearest signal that your content is worth showing to strangers.
REPLY × 0.5 in run_pipeline.py
III
Thou shalt post video — it opens doors text cannot
The model predicts vqv (video quality view) and video_watch_time as distinct continuous action signals. Text and image posts can never trigger these prediction heads. Video posts are scored across more signal dimensions — a structural advantage that exists regardless of production weights.
vqv [6] + video_watch_time confirmed in runners.py
IV
Thou shalt respect the Grox gate — thou must pass it to be ranked
The Grox content pipeline runs spam, policy, and sensitivity classifiers before any scoring occurs. A post flagged by Grox is removed from Phoenix consideration entirely — it is never ranked, never seen. Hashtag stuffing, repetitive copy patterns, or bot-like posting cadence can trigger this gate.
Pre-scoring filter — confirmed in home-mixer architecture
V
Thou shalt not accumulate the four negative signals
NEGATIVE_FEEDBACK_INDICES = [14, 15, 16, 17]not_interested, block, mute, report — are confirmed in runners.py. These signals do not just suppress a single post. They train the model that your content is unwanted for that audience segment, degrading your Phoenix score with those users permanently unless reversed by new positive signals.
NEGATIVE_FEEDBACK_INDICES confirmed in runners.py
VI
Thou shalt stay niche — Phoenix finds thee by embedding similarity
The two-tower retrieval model narrows millions of posts to hundreds using dot-product similarity between user embeddings and post embeddings [B, D=128]. Your post only enters the ranking stage if it's close to what the user tower predicts a user will want. Topically consistent content builds a strong, findable embedding. Off-brand posts dilute it.
Two-tower retrieval — confirmed in phoenix/ architecture
VII
Thou shalt spread posts — author diversity attenuation punishes the burst
Author diversity attenuation is confirmed in the scoring pipeline — subsequent posts from the same author receive a penalty once a threshold is reached in a single feed window. Posting three things in one hour means the third may be scored lower than if you had posted it tomorrow. Distribute posting across accounts and across the day.
Diversity Scorer — 3rd scoring stage in source
VIII
Thou shalt engage in the early window — velocity unlocks Phoenix
Thunder (in-network) provides immediate signal from followers. That early reply and like velocity feeds the model before Phoenix's out-of-network retrieval picks up the post. A post with zero engagement in its first hours rarely enters the Phoenix candidate pool regardless of content quality. Post when your audience is active and reply to early commenters fast.
Thunder Kafka feed + Phoenix retrieval window — architecture docs
IX
Thou shalt not cross-post identical content — the deduplication filter is absolute
The pre-scoring pipeline includes a deduplication filter that removes identical or near-identical posts. Copy-pasting the same content across @kaiotei_, @the1333covenant, and @1333_Theology means two of the three are stripped before scoring. Each account must publish a distinct angle on every topic to get full coverage.
Deduplication — pre-scoring filter confirmed in pipeline
X
Thou shalt post within 80 hours — or the post is dead
POST_AGE_MAX_MINUTES = 4800 is confirmed in source — exactly 80 hours. After that your post exits fresh candidate pools and enters the overflow age bucket, effectively invisible to Phoenix. Every post has an 80-hour window to earn its reach. This also means: posts you schedule must go out on time. A delayed post loses hours from its window permanently.

🔥 Phoenix — Out-of-Network

Two-stage ML: first the two-tower retrieval model narrows millions of posts to hundreds via embedding similarity. Then the Grok-based transformer ranks those candidates using engagement probability predictions.

Embedding similarity
Candidate isolation
Key insight for 1333 Covenant: Thunder is easy to win (just post and engage with followers). The real growth opportunity is Phoenix — the ML system that shows your content to people who don't follow you. Phoenix rewards video, replies, and high engagement velocity in the first 3 hours. All Phoenix strategy points to: make content people want to quote, reply to, and share.
🏗 Home Mixer — Orchestration Layer

home-mixer/ is the Rust/Python service that coordinates the entire For You feed. It uses a composable pipeline framework where each stage (source, hydrator, filter, scorer, selector) is a modular trait that can run in parallel. Nothing is hard-wired — configuration drives everything.

🔍 Pre-Scoring Filters (11 types)

These filters run before the expensive scoring step — failing here means the post is never ranked.

  • Deduplication — removes identical posts
  • Age filter — removes old/stale posts
  • Self-post filter — removes user's own posts
  • Block filter — removes content from blocked accounts
  • Mute filter — removes muted accounts
  • Keyword mute filter — muted words/phrases
  • Previously seen filter — no content reshown
  • Quality filter — baseline quality threshold
  • Spam filter — Grox spam classifier output
  • Policy filter — safety/policy violation checks
  • Sensitive content filter — NSFW/violent content
1333 Covenant action: Ensure never using muted keywords, never triggering spam signals (repetitive posting, unrelated hashtags), and never posting content that could trigger policy filters. One violation can suppress an entire account from Phoenix.

🔥 Two-Tower Retrieval Model

The retrieval stage uses a dual-encoder architecture. Each tower produces a normalized embedding; dot-product similarity finds the top-K candidates from the full corpus before the more expensive ranking step runs.

Embedding [N, D=128]
Implication: Your content's embedding must be similar to high-engagement user profiles to appear in Phoenix retrieval. This is why niche-consistent content with strong topical signals (faith, art, music, tech) outperforms generic posting — the user tower can find you via embedding similarity.

👁 Attention Masking — Candidate Isolation

The key architectural choice that makes scoring consistent and cacheable: candidates cannot attend to each other during ranking. Each post's score depends only on the user context — not what other posts are in the batch.

User → H

Full attention   Self-only (diagonal)   Blocked — confirmed in README: User and History rows have ✗ for all candidate columns

Why this matters: Your post's rank is determined by how the model predicts that user will engage with your content — not by competing with or depending on other posts in the batch. The score is fixed and cacheable per (user, post) pair.
📐 The Scoring Formula
Score = FAV × 1.0 + REPLY × 0.5 + RT × 0.3 + DWELL × 0.2
Source: run_pipeline.py in xai-org/x-algorithm (demo weights — production may differ)

Action indices from the source: IDX_FAV=1 · IDX_REPLY=4 · IDX_QUOTE=5 · IDX_RT=6 · IDX_DWELL=11 · IDX_VQV=13
The model predicts 19 discrete actions total plus 8 continuous actions (e.g. dwell duration).
Quote (5) and video quality view (13) are predicted but not present in the published scoring formula.
All 19 Predicted Actions — Confirmed from runners.py

Complete list sourced from the ACTIONS constant. Previously we listed ~11 generic signals — the actual list has 14 positive + 4 negative discrete actions, plus 3 confirmed continuous actions.

favorite [0] reply [1] repost [2] photo_expand [3] click [4] profile_click [5] vqv — video quality [6] share [7] share_via_dm [8] ★ share_via_copy_link [9] ★ dwell [10] quote [11] quoted_click [12] ★ follow_author [13]

★ = confirmed from source, not in prior versions of this doc

not_interested [14] block_author [15] mute_author [16] report [17]
dwell_time video_watch_time scroll_depth

8 continuous slots total (3 named above + 5 reserved). These measure duration/depth, not binary actions.

Published demo weights (from run_pipeline.py): Favorite × 1.0 · Reply × 0.5 · Repost × 0.3 · Dwell × 0.2. Favorites are highest. Quote, DM-share, VQV, and follow are predicted by the model but not in the published scoring formula. Production weights are not disclosed.
Negative Signals — Confirmed

NEGATIVE_FEEDBACK_INDICES = [14, 15, 16, 17] — confirmed directly in runners.py. Exactly 4 negative discrete actions.

not_interested [14] block_author [15] mute_author [16] report [17] low dwell_score [10] low video_watch_time low scroll_depth
Critical: Negative signals don't just reduce this post's score — they train the model that this user doesn't want this author's content. A cluster of mutes/blocks can suppress your entire account in Phoenix for that user segment going forward.
🌐 Author Diversity Attenuation

After Phoenix scoring, the system applies author diversity attenuation — a score penalty applied to subsequent posts from the same author once a certain number have already been selected. This is why:

  • Posting cadence matters: Flooding posts in a short window means later ones get diversity-penalized even if they score high individually.
  • Three accounts beat one: @kaiotei_, @the1333covenant, and @1333_Theology each have their own author diversity budget — triple the throughput.
  • Format variation helps: Different media types (video vs. text vs. image) may reduce the perceived "sameness" of consecutive posts.
The 3-Hour Window

The Thunder in-memory store and Phoenix candidate retrieval both operate on recency-weighted content. Engagement in the first 3 hours after posting dramatically affects whether your content enters Phoenix's out-of-network candidate pool:

0–30 min
Critical
Seed engagement from close network builds initial score signal
30–90 min
Amplify
Reply velocity signals quality; Phoenix starts considering the post
90–180 min
Phoenix
Out-of-network discovery peaks if early engagement was strong
80h+ (4800 min)
Max age
POST_AGE_MAX_MINUTES = 4800 confirmed in source. Posts beyond 80 hours hit the overflow age bucket — effectively removed from fresh candidate pools.

📋 Pre-Post Checklist

All items sourced exclusively from xai-org/x-algorithm repo analysis.

  • Drive high-weight actions — favorites (1.0×), replies (0.5×), reposts (0.3×), dwell (0.2×) per published scoring formula in run_pipeline.py
  • Video content — triggers vqv and video_watch_time prediction heads; two distinct positive signals unavailable to text posts
  • Topically consistent — Phoenix two-tower retrieval matches via embedding similarity; niche coherence helps the user tower find your content
  • Engage early commenters — reply velocity in the early post window feeds Thunder and influences whether Phoenix picks up the post
  • 3–4 relevant hashtags max — more triggers Grox spam classifier before scoring even begins
  • Triggering negative actions — not_interested [14], block [15], mute [16], report [17] are NEGATIVE_FEEDBACK_INDICES; they suppress Phoenix score for that audience segment
  • Spam patterns — Grox spam classifier runs pre-scoring; hashtag stuffing or repetitive copy removes a post from Phoenix before it is ever ranked
  • Author volume spikes — author diversity attenuation is confirmed in source; late posts from same author receive a score penalty within the same feed window
  • Identical content across accounts — deduplication filter confirmed in pre-scoring pipeline; duplicates are removed before scoring
  • Posting beyond 80 hoursPOST_AGE_MAX_MINUTES = 4800 confirmed in source; posts older than 80 hours fall into the overflow age bucket and exit fresh candidate pools
🔀 Cross-Account Content Strategy

Each account covers a different angle of the same topic — never duplicate exact posts (deduplication filter will remove them).

# Hashtag Strategy

Use 3–4 relevant hashtags max per post. More triggers spam classification in the Grox pipeline. Rotate between these based on content type.

#ChristianArt #FaithInTech #DigitalArt #ChristianMusic #IndieMusic
#SpiritualGaming #FaithTok #GodIsGood #Theology #BibleStudy
#CreativeProcess #BehindTheScenes #IndieCreator #MusicProduction #PixelArt #GameDev #AIArt
💡 Body Keywords (No Hashtag)

Phoenix retrieval uses semantic embeddings — these words in post body text help the user tower match your content to interested audiences even without hashtags.

🌉 Cross-Niche Bridge Content Templates

Bridge content is the most powerful Phoenix tool — it sits at the intersection of two niches and gets discovered by both audiences.

BridgeHook templateTarget audience
Faith + AI "What does it mean to build AI as a Christian? Here's how I think about FaithGPT…" Tech + Christian crossover
Faith + Gaming "Why Battle Angelz TCG was born from Revelation 12 — the theology behind the game" Gamers + theology audience
Worship + Music Production "How worship changed my production style — the moment I stopped making music for streams" Musicians + faith community
Art + Scripture "The most underrated part of Christian art is the theology you don't explain — just show" Artists + theology audience
Tech + Critique "Hot take: most 'Christian AI' is just secular AI with a Bible verse slapped on it" Both audiences — generates quotes

Algorithm Risk Registry

Risks identified from direct analysis of xai-org/x-algorithm source code and pipeline documentation.

HIGH
Author Diversity Attenuation
Confirmed in the repo source: after Phoenix scoring, the pipeline applies author diversity attenuation — a score penalty on subsequent posts from the same author once a threshold is crossed in a given feed window. Spike-posting means later posts get penalized even if they individually score well.
Mitigation: Spread posts across the day · Use all three accounts to triple the author diversity budget · Consistent cadence over volume
HIGH
Negative Action Accumulation
Mutes, blocks, and "not interested" clicks train the model that your content is unwanted for specific user segments. This doesn't just suppress one post — it degrades your Phoenix score for that entire audience segment over time.
Mitigation: Stay on-brand · No clickbait · Monitor mute/block rate per post format · Stop underperforming formats quickly
HIGH
Grox Spam Classification
The Grox content pipeline runs classifiers before scoring. Hashtag stuffing, repetitive copy, or posting patterns similar to spam can trigger classification — removing posts from Phoenix consideration entirely before they're ever ranked.
Mitigation: Max 4 hashtags · Unique copy per post · Organic posting rhythm · No bulk-scheduling bots
MED
Deduplication Filter
The pre-scoring pipeline removes near-duplicate posts. Cross-posting the same content across all three accounts will cause 2 of the 3 to be filtered before scoring. Each account must have distinct copy.
Mitigation: Use the "different angle" cross-account framework · Never copy-paste between accounts
MED
Poor 3-Hour Engagement Velocity
Phoenix uses early engagement velocity to determine whether a post enters out-of-network candidate pools. A post with no replies in the first 3 hours rarely recovers its Phoenix potential regardless of how good the content is.
Mitigation: Post when audience is active · Author replies to early comments · Use event stacking to prime audience
MED
Low Video Retention
The video_view signal includes quality metrics like watch percentage. A video that's skipped in the first 3 seconds sends a strong negative dwell signal — worse than posting no video at all.
Mitigation: Hook in first 2 seconds · Keep clips under 60 seconds · Open with the most compelling visual
LOW
Algorithm Updates
xAI open-sources the algorithm but production weights and model updates are not versioned publicly. Specific engagement weight values can change without notice.
Mitigation: Focus on universal engagement signals (replies, quotes, follows) rather than gaming specific weights — these are stable across algorithm versions
🗺 Implementation Roadmap
Week 1–2
Foundation
Build the base — optimize for Thunder performance
  • Audit current posting patterns — identify which formats generate replies vs. dwell
  • Rewrite bios with discovery keywords: faith, art, music, digital, spiritual, creative
  • Set up posting schedule with times in the calendar view above
  • Identify 3–5 existing posts that could be reformatted for higher engagement
  • Begin reply-first discipline: respond to early comments quickly to build reply velocity before Phoenix's first evaluation window
Week 3–4
Scaling
Launch @1333_Theology and activate Phoenix content
  • Create and optimize @1333_Theology account with theology + digital culture identity
  • Produce first 3-week video content library (short clips, process videos, stream highlights)
  • Publish first set of high-signal posts: hot theology takes, faith + tech bridges
  • Implement cross-account amplification workflow using the angle-differentiation strategy
  • Test 3 different video formats and measure retention rates
Week 5–8
Refinement
Analyze, refine, and scale what's working
  • Weekly post audit — double down on top-performing formats
  • Identify which hashtag combinations drive the most non-follower reach
  • Increase video cadence on the formats with highest retention
  • Build cross-account promotion system — track amplification lift per post
  • Monitor Phoenix share: target 30%+ of impressions from non-followers by week 8
Month 2+
Dominance
Consistent viral-quality content and out-of-network dominance
  • Maintain 3–5 Phoenix-quality posts per week across all three accounts
  • Establish at least one "signature content format" per account that reliably performs
  • Grow community through recommendations, collaborations, and Space partnerships
  • Target consistent non-follower discovery reach above 40% of total impressions
  • Begin 1333 University content series — educational content with high share probability
📌 Key Principles — Stay Algorithm-Proof
  • Engagement over impressions: 100 genuine replies beats 10,000 passive views every time in this scoring model.
  • Reply first, broadcast second: Responding fast to early comments is the cheapest way to boost reply velocity signals.
  • Video is not optional: The model predicts vqv (video quality view) and video_watch_time as distinct action signals. Video-enabled posts have additional prediction heads that text posts cannot trigger — a structural difference regardless of production weights.
  • Authenticity is algorithm-native: The system has no hand-engineered features — it learns from what users actually do. Authentic content that generates real replies outperforms every optimization trick.
  • Three accounts beat one: Author diversity attenuation is real. Three accounts means three times the candidate budget before diversity penalties kick in.
  • Negative signals compound: One bad post format that generates mutes will suppress your score in that audience segment for weeks. Monitor and retire underperforming formats fast.
