X served 150 posts; the first 80 or so were about the model, and the rest were unrelated older posts that happen to contain the words (Freddie Mercury lists, the Phoenix Mercury, planets, astrology). Those unrelated posts are not listed; the ones about AI releases are, as off_topic or neutral. A second Top query, \"Mercury 3\" (diffusion OR inception OR LLM OR model OR @_inception_ai), read at about 18:25 UTC, added 17 posts not in the first sample (one post with no readable text, by @0xAlphana, was skipped). X's Top tab favours the loudest, most-engaged posts, and it also served a few pre-launch posts about the Mercury 3 Preview (early access from about 7 October).", "hacker_news": "Every top-level comment on https://news.ycombinator.com/item?id=50155245 (\"Mercury 3: Diffusion at scale\", link to Inception's blog post, submitted 19 October 2026 17:27 UTC), read through the HN Algolia API at about 18:34 UTC, when the story had 93 points, 37 comments and 19 top-level comments.
