Claim
Almost one year ago now, a company named XBOW announced that their AI had achieved "rank one" on the HackerOne leaderboard.
Correction

XBOW’s own “Top 1” announcement is dated June 24, 2025—about 8 months before this LessWrong post (Feb 19, 2026), not “almost one year.”

Full reasoning

Why this is incorrect

  • The LessWrong post itself is dated February 19, 2026.
  • XBOW’s “The road to Top 1: How XBOW did it” post—the announcement being referred to—is dated June 24, 2025.

From June 24, 2025 to February 19, 2026 is ~7 months and 26 days (about 8 months), which is materially short of “almost one year.”

Evidence

  • LessWrong publication date: 19th Feb 2026
  • XBOW announcement date: June 24, 2025

Claim
It's almost a year later, after the releases of o3, GPT-5, GPT-5.1, GPT-5.2, and now GPT-5.3.
Correction

The XBOW announcement post being discussed is dated June 24, 2025, so by Feb 19, 2026 it’s been about 8 months, not “almost a year later.”

Full reasoning

Why this is incorrect

In context, “the report” refers to the XBOW announcement about reaching the top of the US HackerOne leaderboard.

  • XBOW’s announcement (“The road to Top 1: How XBOW did it”) is dated June 24, 2025.
  • This LessWrong post is dated February 19, 2026.

That gap is ~8 months, not “almost a year later.”

Evidence

The publication dates on both pages establish the timeline directly.
