  • Therefore, we propose MemDocAgent, a long-horizon agentic framework that generates documentation within a single, integrated context spanning the entire repository.

What's new

Methods: We conduct a controlled diagnostic study on a curated 17-sample set of production-helper signature changes from five Python repositories.

Key details

  • Objectives: We study whether temporally stale repository snippets act as harmless noise or actively induce current-state-incompatible code.
  • Methods: We conduct a controlled diagnostic study on a curated 17-sample set of production-helper signature changes from five Python repositories.
  • For each sample, we compare current-only, stale-only, no-retrieval, and mixed current/stale retrieval conditions under prompts that hide commit freshness and expected current signatures.
  • Results: Under neutralized prompts, stale-only retrieval induces stale helper references on 15/17 Qwen2.5-Coder-7B-Instruct samples and 13/17 gpt-4.1-mini samples, corresponding to 88.2 and 76.5 percentage-point increases over current-only retrieval.

Context

SynthRAD2025 demonstrates that deep learning yields clinically relevant sCTs, especially for CBCT-to-CT, while identifying persistent MRI-to-CT challenges and underscoring dose-based evaluation as essential for clinical validation.

What's new

Building on SynthRAD2023, SynthRAD2025 benchmarked sCT methods on 2,362 patients from five European centers across head and neck, thorax, and abdomen.

Key details

  • Repeated CT acquisitions impose radiation exposure and logistical burdens, MRI lacks electron density, and cone-beam CT (CBCT) requires correction for dose calculation.
  • Synthetic CT (sCT) generation addresses these by converting MRI or CBCT into CT-equivalent images with accurate Hounsfield Unit (HU) values, enabling MRI-only RT and CBCT-based adaptive workflows.
  • Building on SynthRAD2023, SynthRAD2025 benchmarked sCT methods on 2,362 patients from five European centers across head and neck, thorax, and abdomen.

A collection of DESIGN.md files inspired by popular brand design systems.

What's new

DESIGN.md is a new concept introduced by Google Stitch.

Key details

  • Drop one into your project and let coding agents generate a matching UI.
  • Copy a DESIGN.md into your project, tell your AI agent "build me a page that looks like this" and get pixel-perfect UI that actually matches.
  • DESIGN.md is a new concept introduced by Google Stitch.
  • A plain-text design system document that AI agents read to generate consistent UI.

Results & evidence

  • No hard numbers surfaced in the source text; treat claims as directional until benchmarks appear.

Limitations / unknowns

  • Generalization outside curated tasks is still unclear.

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.

TabPFN-3: Technical Report

Signal 9.4 Novelty 4.0 Impact 2.0 Confidence 8.7 Actionability 6.5

Summary: arXiv:2605.13986v1 Announce Type: new Abstract: Tabular data underpins most high-value prediction problems in science and industry, and TabPFN has driven the foundation model.

  • What happened: TabPFN-3 introduces test-time compute scaling to tabular foundation models.
  • Why it matters: Our API offering TabPFN-3-Plus (Thinking) exploits this to beat all non-TabPFN models by over 200 Elo on TabArena, rising to 420 Elo on the largest data subset, and.

arXiv:2605.13986v1 Announce Type: new Abstract: Tabular data underpins most high-value prediction problems in science and industry, and TabPFN has driven the foundation model revolution for this modality.

Key details

  • Designed with feedback from our users, TabPFN-3 builds on this foundation to scale state-of-the-art performance to datasets with 1M training rows and substantially reduce training and inference time.
  • Pretrained exclusively on synthetic data from our prior, TabPFN-3 dramatically pushes the frontier of tabular prediction and brings substantial gains on time series, relational, and tabular-text data.
  • On the standard tabular benchmark TabArena, a forward pass of TabPFN-3 outperforms all other models, including tuned and ensembled baselines, by a significant margin, and pareto-dominates the speed/performance frontier.
  • On more diverse datasets, TabPFN-3 ranks first on datasets with many classes, and beats 8-hour-tuned gradient-boosted-tree baselines on datasets up to 1M training rows and 200 features.
