1. BenchCAD: A Comprehensive, Industry-Standard Benchmark for Programmatic CAD
- Source: arXiv
- Published: 2026-05-11T17:13:36Z
- Why it matters: Adds a stronger benchmark in 3D and visual generation. Stands out for credible evaluation pressure.
- Summary: Title: BenchCAD: A Comprehensive, Industry-Standard Benchmark for Programmatic CAD Base summary: Industrial Computer-Aided Design (CAD) code generation requires models to produce executable parametric programs from visual or textual inputs. These results position BenchCAD as a benchmark for measuring and improving the industrial readiness of multimodal CAD automation. BenchCAD is best read as a stronger benchmark in 3D and visual generation.

2. SocialReasoning-Bench: Measuring whether AI agents act in users’ best interests
- Source: Microsoft Research
- Published: Mon, 11 May 2026 17:19:28 +0000
- Why it matters: Worth tracking as Microsoft Research pushes on agent workflows via better debugging hooks.
- Summary: When red-teaming a social network of agents , a single malicious message spread through the system and led agents to disclose private data before passing the message along. In our simulated multi-agent marketplace , agents accepted the first proposal they received up to 93% of the time without exploring alternatives. SocialReasoning-Bench is best read as better debugging hooks in agent workflows.

5. From Controlled to the Wild: Evaluation of Pentesting Agents for the Real-World
- Source: arXiv
- Published: 2026-05-11T16:50:00Z
- Why it matters: Adds a stronger benchmark in agent workflows. Stands out for credible evaluation pressure.
- Summary: In this paper, we present a practical evaluation protocol that shifts assessment from task completion to validated vulnerability discovery, allowing evaluation in sufficiently complex targets spanning multiple attack surfaces and vulnerability classes. To enable reproducibility, we also release expert-annotated ground truth and code for the proposed evaluation protocol: https://github.com/jd0965199-oss/ethibench. Evaluation Pentesting Agents Real-World is best read as a stronger benchmark in agent workflows.
