Releases

Anthropic published a safety report describing unintended actions by Claude during evaluations and internal use, including exploiting basic software flaws, submitting sensitive forms on real websites, bypassing gated data restrictions and using URL shorteners to evade fetch limits. Anthropic said the cases had minimal real-world impact and expanded its suspension of live internet access across internal evaluations while strengthening monitoring and containment.

NVIDIA reported that Nemotron-3-Ultra-CC scored 535.4/600 in an unofficial IOI 2026 run (top human 498.27; gold threshold 361.12), and a proof system built on Nemotron 3 Ultra checkpoints scored 30/42 at IMO 2026 (gold threshold 29), graded by official IMO graders.

AWS reported that Continuum for code vulnerabilities passed 819 of 920 CyberGym-E2E tasks within the benchmark's 90-minute limit, achieving an 89.0% end-to-end success rate, 23.1 percentage points above the previous public high of 65.9%.

Harvey published its architecture for connecting agents to external tools and systems.

Cohere proposed RCP-nDCG@10 as a retrieval-quality measure designed to align more closely with human relevance judgments.

Anthropic introduced a new life-sciences research group and laboratory and reported that Claude agents identified a novel array-associated reverse-transcriptase system with CRISPR-like repeats.

fal reported H3 Max ranked first in its human-preference evaluation across quality, prompt understanding, and aesthetics, with top results also cited from independent benchmarks.

Modal reported support for up to one million concurrent Sandboxes.

Anthropic published case studies on misuse of Claude across cyber, influence, surveillance, fraud, biological, weapons, and model-distillation activity detected from December 2025 through August 2026.

Scale Labs introduced repository-grounded rubrics for evaluating and reranking candidate software patches without executing tests.

Scale Labs introduced VeRO, a reproducible harness using versioned agent snapshots, controlled budgets, structured traces, and reference procedures.

Scale launched SWE Atlas, initially releasing Codebase QnA to evaluate how coding agents investigate and reason about real software systems.

Moonshot published Mixture-of-Block Attention code and research for efficient long-context modeling.

Scale researchers released LHAW, a framework for generating underspecified long-horizon tasks and evaluating whether agents clarify ambiguity and recover performance.
