Notable: appears on the official Terminal-Bench leaderboard (tbench.ai, Terminal-Bench 4.0 — the only version tbench.ai currently shows), best rank #21; only five distinct agents are listed there, so every one is top-10. Scores are TB 4.0 resolution rates (best per model across reasoning efforts), fetched 2026-10-14 — not comparable with older Terminal-Bench 2.x figures. releaseDate null: x.ai's 2026-08-19 post says Grok Build was introduced 'in July' as an Early Beta without giving a day. x.ai/build itself returned 403. 'web' covers the in-chat app builder on web/iOS/Android described in the same post.
