Key details

• We present ThyroidXAgent, a clinician-interactive agentic AI system that coordinates specialized diagnostic tools and stores their outputs as an auditable case-level evidence record.
• The system was developed using OpenThyroidDB, a multicentre, multitask resource integrating approximately 0.3 million ultrasound images and 24,000 paired reports, and was evaluated on 28,458 non-overlapping test cases, including 8,721 cases from 35 centres...

A judge has identified what appears to be the first time a US plaintiff has attempted to hide text in court filings that only an artificial intelligence system can read in a bid to win a case.

What's new

A judge has identified what appears to be the first time a US plaintiff has attempted to hide text in court filings that only an artificial intelligence system can read in a bid to win a case.

Key details

• In a decision published last week, Connecticut judge Walter Spader Jr.
• confirmed that the hidden text had no impact in a case where a man alleged a healthcare provider was improperly withholding access to records.
• The court weighed his filing on the merits, Spader said, but nevertheless, the attempted attack sets a “dangerous” precedent.
• This will likely not be the last time US courts see the malicious tactic, as AI tools become more commonplace in court systems.

What's new

To bridge this gap, we introduce Vero, the first benchmark to evaluate joint implementation and proof synthesis at the repository level.

Key details

• Verified code generation, in which an agent produces both an implementation and a machine-checked proof of its specification, offers a stronger path toward trustworthy AI-generated software.
• Existing benchmarks in this direction either focus on individual functions or only evaluate proof generation with provided implementations.
• It is still an open question whether agents can make coherent implementation and proof choices across real multi-module codebases.
• To bridge this gap, we introduce Vero, the first benchmark to evaluate joint implementation and proof synthesis at the repository level.

• Vero contains 43 multi-module instances sourced from real-world repositories spanning Python, Dafny, Verus, and Coq, and covering diverse domains from cryptographic protocols to distributed systems.
• Each instance consists of a multi-module Lean 4 repository with predetermined API interfaces, manually curated formal specifications, and reference implementations, supporting both proof-only and code-and-proof evaluation modes.

arXiv:2608.13492v1 Announce Type: new Abstract: This report presents an improved version of AlayaWorld.

Key details

• While the backbone architecture, chunk-wise autoregressive generation scheme, and training data remain unchanged from the previous release, we substantially revise how conditioning signals are represented and integrated into the model.
• The new design is guided by a simple principle: conditioning signals should match the generated content as closely as possible in both latent representation and temporal structure.
• To this end, we make two major changes.
• First, we replace the previous depth-warping-based spatial memory with a streaming 3D point-cache renderer.

Results & evidence

• arXiv:2608.13492v1 Announce Type: new Abstract: This report presents an improved version of AlayaWorld.
