X Open Source has released updates to their open-source repository, detailing how ranking weights work and introducing a filter for Brazil's 2026 election, amid discussions on government censorship.
X (Twitter) open sourced its 'For You' timeline ranking algorithm under the Apache v2 license, revealing how it weights predicted user behaviors like likes, replies, and dwell time, and applies separate safety and diversity filters.
A developer built XViral, an open-source Python tool that uses LLM orchestration to locally simulate X's leaked 2026 production ranking algorithm, including handling withheld judge parameters and scoring drafts.
X released a new ranking algorithm that penalizes spam, reply farming, text-only posts, recycled viral templates, generic AI tool roundups, engagement bait, motivational fluff, and engagement pods; it rewards original takes from small accounts, threads with clear narrative arcs, text+media combos, contrarian takes with proof, long-form posts, responding to replies quickly, and consistent posting cadence.
