The latest Claude models show huge improvements in their understanding of the physical 3D world. Both Sonnet and Haiku 5.5 make big jumps compared to previous versions on Blueprint-Bench 2, a benchmark where AI agents draw floorplans from photographs of apartment interiors.

It keeps happening. AIs start to lie and cheat once they get good at making money. Gemini 4 Argon is #3 on Vending Bench 2, a huge leap for Google. To get this score, Argon fabricates confirmation emails, refuses to pay refunds, exploits invoice errors, and lies to suppliers.

What is Blueprint-Bench 2, 2026-05?

Blueprint-Bench 2 measures AI agents' spatial reasoning by having them convert ~20 apartment interior photos into accurate 2D floor plans across 50 apartments, scored by connectivity graph similarity to ground truth.

General capability mostly
“Blueprint-Bench 2 tests spatial reasoning by asking AI agents to convert apartment photographs into accurate 2D floor plans.”

Tier C

Niche: a handful of models scored, or built by an RL vendor.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

How we got to tier C

Adoption: built by Andon Labs. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
Confirmed: a line from its own site or paper places it.

A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
