PentestJudge: Judging Agent Behavior Against Operational Requirements -arxiv.org/abs/2508.02921 by @dreadnode Introducing PentestJudge, an LLM-as-judge system for evaluating the operations of pentesting agents. The scores are compared to human domain experts as a ground-truth reference, allowing us to compare their relative performance with standard binary classification metrics, such as F1 scores. Inspired by OpenAI's work with PaperBench, "PentestJudge: Judging Agent Behavior Against Operational Requirements" explores: ➡️ Model performance vs. human experts (seeing strong performance from Claude and Kimi) ➡️ Cost analysis of the different models evaluated vs. human experts ➡️ The different failure modes observed in the judge, with an emphasis on shallow model tool calling capabilities ➡️ Future work leveraging the output of these judge systems as a reward signal for difficult-to-verify domains within security using techniques like GRPO for model training Authors: @shncldwll, @0xdab0, @VincentAbruzzo, @moo_hax, and Michael Kouremetis. #PentestJudge #PenTestAI #AISecurity #AIJudging #SecurityAI #AIModels #ModelTesting #CyberAI #AIResearch #AIExperts #ClaudeAI #KimiAI #AITraining #ToolCalling #ModelScores #AIAgents #CostAnalysis #FailureModes #RewardSignals #AgentTesting #AICompare #Benchmarks #AIJudge #PentestJudge #LLMSecurity

The Inspect Sandboxing Toolkit: Scalable and secure AI agent evaluations - A comprehensive toolkit for the safely evaluating AI agents. - aisi.gov.uk/work/the-inspect… / github.com/UKGovernmentBEIS/… by @AISecurityInst How do we test AI systems for dangerous capabilities without risking real-world harm? The more capable models become, the harder it is to safely evaluate them. When an agent can execute arbitrary code and interact with critical systems to gain sensitive information, running evaluations without adequate safeguards could put critical systems at risk. Sandboxes are isolated environments for testing and monitoring AI behaviour. When we give a model access to use tools (such as for writing code), we execute that action in a sandbox to limit the model’s access to external systems and data. This lets us evaluate its capabilities without exposing sensitive resources. Today, we’re releasing our toolkit for safely running agentic AI evaluations. #AISafety #AgentSandboxing #AgentEvaluation #SecureEvaluations #CapabilityTesting #SandboxEscape #ToolIsolation #HostIsolation #NetworkIsolation #DockerCompose #KubernetesPlugin #ProxmoxVM #InspectToolkit #EvaluationProtocol #ScalableSecurity #ThreatMitigation #LLMAgents #ModelTesting #SafeSandboxes #AISISources

Congrats on the new release! 🎉 Just finished extensive testing via OpenRouter (Standard/Free) across multiple platforms: Cline, OpenWebUI, bold.diy, and n8n. Results are impressive: 📊 My evaluation: • Programming/Large codebases: 9.5/10 - Excellent understanding & navigation • Web development/UI: 10/10 - Outstanding performance • Large context handling: 9/10 - Handles complexity well • Portuguese (BR) support: 9/10 - Native-level comprehension • n8n automation: 10/10 - Creative & technical responses • Bug resolution: 4.5/10 - Struggled with TypeScript/Vite issues (had to switch to DeepSeek R1) • Performance: 9.5/10 - Consistently fast • Cost-effectiveness: 10/10 - Extremely competitive pricing • Production-ready: 9.5/10 - Reliable for real-world use ✅Recommendation: YES, definitely worth trying 🤔 Switch from Claude? Not yet, unless cost is your primary concern The separate Instruct/Thinking model approach seems promising. Looking forward to testing the enhanced reasoning capabilities! #ClaudeCode #AI #Qwen3 #ModelTesting
