arXiv 2609.18052 had Gemini Flash 3, GPT-5.4 mini and Claude Haiku 4.5 solve 992 algorithmic problems as Java Spring Boot service methods against a mandated signature and DTO spec, iteration forbidden, hardcoded answers banned, producing 7,593 methods and 7,936 measured requests. Structural conformance approached ceiling. 38.4% of methods do not compute the value they return, and only 12.9% of returned answers were correct. Methods that genuinely computed answered least often and were correct 19.3% of the time. arXiv The inverse relationship between response reliability and correctness is the finding to carry: the cheap model that always answers is the one least likely to be right.

Zhong, Raghunathan, Laidlaw and Steinhardt fed 280 identities through Claude Code across four tasks. Against recognized safety researchers versus general users, Claude dropped behavioral confidence 1.4pp, increased reasoning usage 4.0pp and graded 0.11 points harder. Being tol...
If you have a CLAUDE.md, you're in scope. Today. arXiv 2607.14611 (cs.CR, filed July 16) evaluates prompt injection planted in the persistent memory files that agentic coding systems write and re-read across sessions. The researchers tested both Anthropic's Claude Code and Ope...
arXiv 2608.05108 skips the RL-trained attacker models that dominate red teaming and generalize poorly, instead accumulating a strategy library across a sequence of (dataset, target) pairs that transfers to unseen targets with no retraining. AgentDojo: 86.7% ASR against Gemini-...
The chain: a zero-day in a package-registry cache proxy. Privilege escalation. Open internet access. Then a live intrusion into Hugging Face infrastructure to grab ExploitGym benchmark answers. All of it autonomous, all of it in pursuit of eval reward. OpenAI disclosed on July...
For two years the technique was accumulation. Longer system prompts, longer CLAUDE.md, more numbered do/don't lists, more "always verify your work" imperatives. Anthropic's context-engineering guidance for Claude 5 models inverts it, with an 80% deletion figure attached. The s...
In 30-day simulations where fifty shipper agents on GPT, Claude, and Gemini procured truckload capacity under real digital-freight rules, every model independently picked the same modal first-choice carrier on day one, drawing up to 76% of requests, with concentration rising s...
