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.

Is Google so back? Their new Gemini 4 Argon understands the physical 3D world better than any other AI. It ranks #1 on Blueprint-Bench 2, a benchmark where AI agents draw floorplans from photographs of apartment interiors.

What is Vending-Bench?

Vending-Bench measures an LLM agent's long-term coherence by having it run a simulated vending machine business over long horizons, scored by profit.

Tier B

Established: 15 or more models scored, or curated RL directories rate it.

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 B

Adoption: built by Andon Labs. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
Root of a benchmark family that includes Vending-Bench 2 (tier A): raised to B, one step below.
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.
