3+ day, 7+ hour ago   (298+ words) Google has open-sourced Mantis, a stack-agnostic toolkit of security review skills that lets an AI coding agent run the whole vulnerability lifecycle. It finds a suspected flaw, strips the false positives, reproduces the bug inside a sandbox, writes a minimal…...

1+ week, 2+ day ago   (499+ words) Today, OpenAI released GPT-6 Astra. The company calls it its most intelligent and aligned model, and positions it primarily as a computer-use system rather than a chat model. The pitch is that Astra operates software the way a person does,…...

1+ week, 4+ day ago   (370+ words) Yes, Claude Fable 5.1 is generally available as claude-fable-5-1 on the Claude API, Amazon Bedrock, Claude Platform on AWS, Google Cloud, and Microsoft Foundry. Claude Mythos 5.1 is not: it is restricted to vetted US organizations inside Project Glasswing. On Terminal-Bench-Science 0.1, an…...

3+ week, 6+ hour ago   (506+ words) MarkTechPost In this tutorial, we build an in-depth NeMo Guardrails pipeline that demonstrates how layered guardrails can control an LLM-based financial assistant across the full request lifecycle. We combine deterministic PII detection and redaction, LLM-based input and output self-checks, retrieval…...

3+ week, 1+ day ago   (323+ words) Yes, but only on one path. Claude Security is available in public beta for Claude Enterprise customers. There is no separate model add-on; Mythos 5 scans are billed as standard token usage under the existing plan. An admin enables it in…...

3+ week, 4+ day ago   (278+ words) Partially, the engineering is production-shaped, but the public mesh is still labelled a beta testnet. A node joins with sam-node join, then runs with sam-node run. libp2p uses 5001/udp and 5002/tcp; the local MCP API defaults to 8080. The consequence: nodes authorize…...

1+ mon, 5+ day ago   (425+ words) MarkTechPost Yes, but only inside OS-level isolation. NOOA is Apache 2.0, installs with pip install nooa (v0.0.8, released July 30, 2026), and requires Python 3.12–3.13. PyPI classifies it as alpha, and NVIDIA describes it as a research preview. Agents can execute LLM-generated code, and NVIDIA…...

1+ mon, 1+ week ago   (383+ words) Agents, MCP integrations, and LLM-powered applications are entering codebases faster than most security programs can track them. Mend.io’s new practitioner guide, ‘Securing AI agents, MCP servers & LLM apps: A practical framework’, targets that gap. It is organized around three…...

1+ mon, 1+ week ago   (214+ words) Not open-sourced or weight. VR-1 is available only to vetted organizations through the Cogent Frontier Access Program, with guardrails, policy controls, and audit logging in place, and participants work directly with Cogent Research on evaluation and deployment in their own…...

1+ mon, 2+ week ago   (367+ words) Sakana AI has released Fugu-Cyber (model ID is fugu-cyber-v1.0), a cybersecurity-specialized addition to its Fugu orchestration family. It is not just a new frontier model. It is a third endpoint on the Fugu orchestrator, tuned for security reasoning. Sakana launched…...
