Source-verification audit: fix fabrications, rename PI slugs, link hygiene, add foundational pages - Re-verified all 195 pages vs original sources; removed 47 confirmed fabricated tables/numbers, restored 19 false-positive deletions (full-PDF re-check) - Renamed PI tech-report slugs ICLR-2026-pi07/pi06/RECAP -> PI-pi07/PI-pi06/PI-RECAP (these are PI technical reports, not ICLR 2026 papers); updated 171 wikilinks - Fixed 60 broken wikilinks -> 0 dangling across the wiki - Added foundational pages: OpenVLA, ReKep, AgiBot World Colosseo, RoboBrain 2.0; linked from Home + sidebar + venue indexes Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add VLA attention architectures cross-paper review + correct π series attention - New Review-VLA-Attention.md: per-family attention deep dive (π series, GR00T N1→N1.7, StarVLA, NORA/Qwen-VL) with mermaid topology diagrams and HTML colored mask matrices for block-causal / causal / bidirectional / prefix-LM. - Correct π0.5/π0.6/π0.7 attention story per π0.7 paper Appendix B: π0.5 used global bidirectional attention (image + text), π0.7 introduces conditional block-causal that falls back to π0.5-style global bidir when no subgoal images are in the prompt. - pi-series-evolution.md: rewrite Attention mask row to reflect Appendix B. - Review-pi07.md §4.1: replace single-line attention bullet with conditional-on-image-goals description quoting Appendix B directly. - Home.md: link the new Review-VLA-Attention page in cross-paper reviews.
Add π0.7 page and π-series evolution comparison π0.7 (Apr 16, 2026) is Physical Intelligence's new steerable generalist VLA, succeeding π0.6. Key novelties: MEM video-history encoder, world- model subgoal-image prompting, episode-metadata + control-mode prompt conditioning with per-component dropout, CFG on metadata, and heavy use of suboptimal / autonomous / RL-rollout data distilled via metadata. Matches RL-specialist performance out-of-the-box and demonstrates the first strong signs of compositional generalization in the π series. New pages: - ICLR-2026-pi07.md — per-paper page - pi-series-evolution.md — model/data/training side-by-side for π0 → π0.7 Updated: - ICLR-2026-pi06.md (marked superseded, forward-link) - ICLR-2026.md, _Sidebar.md, Home.md (navigation) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
