X Algorithm Update: New Posts No Longer Cut First, Small Accounts Gain Fair Exposure

Several developers who have long tracked X's open-source recommendation code confirmed that X made significant changes to the For You feed algorithm this week: new posts are no longer prioritized for trimming, small accounts get notably better reach, and the platform will also take measures against low-quality posts.

Confirmed

ThePeterMick (who tracks X algorithm changes daily with Claude) and faraz0x, who read the open-source code himself, both note that X only checks about 2,800 posts per For You refresh, with candidates drawn from a pool of about 3,700—anything beyond is cut directly.
Previously, new posts sat at the end of the candidate queue and were the first to be cut when the limit was exceeded, leaving new posts from small accounts with almost no exposure.
This update adds a fair-share filter: new posts are no longer trimmed first, giving small accounts more equitable reach.
Low-quality posts will be flagged with warning labels and barred from interactions (mentioned in both faraz0x's and ThePeterMick's summaries).
faraz0x's conclusions come from directly reading X's open-source recommendation code, making this a fairly first-hand source.

Why It Matters

For creators, higher survival rates for new posts make cold-start growth more feasible for small accounts, and post timing strategy may matter less.
Low-quality post warnings and interaction bans show X is adding quality-governance levers beyond the ranking layer.
ThePeterMick also relayed advice from adamboxer1: when you see a good post, don't just like it—reply and quote-tweet, which helps good content enter the candidate pool—showing the community is already adapting its engagement strategies accordingly.
