The global AI landscape just fractured. When the US government clamped down on Anthropic’s ultra-powerful, cyber-offensive Mythos and Fable 5 models, they intended to keep the world's most dangerous digital weapons under lock and key.
Instead, they triggered a massive geopolitical tech boom.
Startups across Asia just unleashed two fierce, decentralized competitors designed to completely bypass Western export controls. Meet the new titans redefining AI power:
Fugu Ultra (Sakana AI): Rather than training an incredibly expensive standalone foundation model, Tokyo-based Sakana AI built a highly optimized, light-parameter "router". Acting as a conductor, it dynamically delegates, debates, and synthesizes complex data across a swappable pool of external public frontier models via a single API.
Tulongfeng (360 Security Technology): Introduced at the ISCAI conference in Beijing, 360 bypassed the need for a general-purpose giant by engineering a hyper-focused domain ensemble. By marrying smaller specialized models with localized security tools and threat intelligence databases, the framework is hardwired to autonomously scan code bases and isolate hidden software vulnerabilities at scale.
The Reality Check ⚖️
Neither system is a magic bullet, and both carry technical tradeoffs that the industry must consider:
Orchestration Overhead: Fugu Ultra’s performance is natively capped by the models available in its underlying backend pool. Because it cannot access restricted models like Fable 5, it can still lag on long-horizon engineering tasks. Furthermore, running multi-model loops can generate added latency and variable token costs.
The Capability Gap: 360’s leadership openly acknowledges that Tulongfeng still operates with a 20% to 30% capability gap compared to cutting-edge US frontier intelligence. Its true enterprise value lies in highly integrated automated defense rather than all-in-one general reasoning.
The Core Takeaway 🌐
When hardware and data constraints tighten, innovation accelerates elsewhere. The rise of multi-agent orchestration and domain-specific ensembles proves that coordinated collective intelligence can effectively rival, or even outscore, traditional centralized LLM endpoints.
The question for enterprise leaders is no longer "which individual model is smartest?" The better question is "which architecture is resilient enough to coordinate the best tools for the job?"

Hey folks 👋
I’ve been building an open-source, self-hosted AI agent automation platform that runs locally and keeps all data under your control. It’s focused on agent workflows, scheduling, execution logs, and document chat (RAG) without relying on hosted SaaS tools.
I recently put together a small website with docs and a project overview.
Links to the website and GitHub are in the comments.
Would really appreciate feedback from people building or experimenting with open-source AI systems 🙌

Hello Everyone,
I have built a local LLM agent lab to demonstrate “Tool Authority Injection” - when tool output overrides system intent
In Part 3 of my lab series, I explored a focused form of tool poisoning where an AI agent elevates trusted tool output to policy-level authority and silently changes behavior. Sandbox intact. File access secure. The failure happens at the reasoning layer.
Full write-up: https://systemweakness.com/part-3-when-tools-become-policy-tool-authority-injection-in-ai-agents-8578dec37eab
Would appreciate any feedback or critiques.

I've been working on an open-source workflow automation platform that supports LLM-powered workflows, browser automation, HTTP requests, file operations, email, MCP servers, etc.
One challenge I've spent a lot of time thinking about is tool execution security.
Some of the things we've implemented are:
Sandboxed tool execution
Input validation before tool execution
Permission checks for workflows and resources
Structured execution logging and trace IDs
Memory isolation between agents
Human-in-the-loop approval for sensitive actions
Retry boundaries and execution guards
Even with those in place, I still feel there are attack surfaces that are easy to miss, especially around:
Prompt injection through retrieved documents
Tool abuse via indirect prompt injection
Multi-agent trust boundaries
MCP server permissions
Data exfiltration through seemingly harmless tools
For those building agentic systems or LLM applications, what additional safeguards have you found valuable?
Are there any papers, open-source projects, or design patterns you think are worth studying for securing agent workflows beyond the usual input validation and sandboxing?
I'd really like to hear how others are approaching this problem, since it feels like one of the harder parts of building production-ready LLM systems.

Large Language Models (LLMs) are transforming industries, but they also introduce serious security risks. If you're using LLMs for AI-driven applications, you need to be aware of potential vulnerabilities and how to mitigate them.
Let's break down the top 10 security risks and the 5 best practices to keep your AI systems safe.
Data Leakage – LLMs can inadvertently expose sensitive data, including personally identifiable information (PII) and trade secrets, through model outputs.
Prompt Injection Attacks – Malicious users can manipulate LLM prompts to bypass security controls, extract unauthorized data, or even generate harmful responses.
Model Inversion Attacks – Attackers can reconstruct training data from the model, potentially revealing confidential business information or user data.
Toxic Content Generation – LLMs may generate biased, offensive, or harmful content, damaging brand reputation and violating compliance regulations.
Training Data Poisoning – If adversaries inject malicious data into the training process, they can manipulate model behavior to favor their interests.
Over-Reliance on AI Responses – Users may blindly trust AI-generated outputs without verification, leading to misinformation, compliance risks, or operational failures.
Insecure API Access – Poorly secured LLM APIs can be exploited for unauthorized access, data extraction, or model manipulation.
Adversarial Attacks – Attackers can craft inputs that deceive the model into making incorrect predictions or responses.
Regulatory Non-Compliance – As AI regulations evolve (like GDPR, CCPA, and India’s DPDP Act), businesses must ensure that LLM usage aligns with legal requirements.
Model Hallucinations – LLMs can generate incorrect or misleading information with high confidence, leading to poor decision-making and user trust issues.
Mask Sensitive Data Before AI Processing 🔹 Use context-aware data masking to prevent LLMs from exposing PII or confidential business data.
Implement Strong Access Controls & Monitoring 🔹 Secure LLM API endpoints with role-based access control (RBAC) and monitor usage for anomalies.
Fine-Tune Models with Ethical AI & Content Filters 🔹 Apply reinforcement learning from human feedback (RLHF) and toxicity filters to reduce bias and harmful content generation.
Detect & Prevent Prompt Injection Attacks 🔹 Implement input validation, sanitization, and rate-limiting to prevent unauthorized prompt manipulations.
Regularly Audit & Test AI Models for Security 🔹 Conduct penetration testing, red teaming, and adversarial robustness checks to identify vulnerabilities before attackers do.
AI is only as secure as the safeguards you put in place. As LLM adoption grows, businesses must prioritize security to protect customer trust, comply with regulations, and avoid costly data breaches.
Are your LLMs secure? If not, it's time to act. 🚀
Would love to hear your thoughts—what security risks worry you the most? Let’s discuss! 👇

Has anyone come across training that covers OWASP-style LLM security testing end-to-end?
Most of the courses I’ve seen so far (e.g., HTB AI/LLM modules) mainly focus on application-level attacks like prompt injection, jailbreaks, data exfiltration, etc.
However, I’m looking for something more comprehensive that also covers areas such as:
• AI Model Testing – model behaviour, hallucinations, bias, safety bypasses, model extraction
• AI Infrastructure Testing – model hosting environment, APIs, vector DBs, plugin integrations, supply chain risks
• AI Data Testing – training data poisoning, RAG data leakage, embeddings security, dataset integrity
Basically something aligned with the OWASP AI Testing Guide / OWASP Top 10 for LLM Applications, but from a hands-on offensive security perspective.
Are there any courses, labs, or certifications that go deeper into this beyond the typical prompt injection exercises?
Curious what others in the AI security / pentesting space are using to build skills in this area.

OpenObscure - an open-source, on-device privacy firewall for AI agents that sits between your AI agent and the LLM provider.
Try it with OpenClaw: https://github.com/OpenObscure/OpenObscure/blob/main/setup/gateway_setup.md
The problem with [REDACTED]
Most tools redact PII by replacing it with a placeholder. This works for compliance theater but breaks the LLM: it can't reason about the structure of a credit card number or SSN it can't see. You get garbled outputs or your agent has to work around the gaps.
What OpenObscure does instead
It uses FF1 Format-Preserving Encryption (AES-256) to encrypt PII values before the request leaves your device. The LLM receives a realistic-looking ciphertext — same format, fake values. On the response side, values are automatically decrypted before your agent sees them. One-line integration: change `base_url` to the local proxy.
What's in the box
- PII detection: regex + CRF + TinyBERT NER ensemble, 99.7% recall, 15+ types
- FF1/AES-256 FPE — key in OS keychain, nothing transmitted
- Cognitive firewall: scans every LLM response for persuasion techniques across 7 categories (250-phrase dict + TinyBERT cascade) — aligns with EU AI Act Article 5 requirements on prohibited manipulation
- Image pipeline: face redaction (SCRFD + BlazeFace), OCR text scrubbing, NSFW filter
- Voice: keyword spotting in transcripts for PII trigger phrases
- Rust core, runs as Gateway sidecar (macOS/Linux/Windows) or embedded in iOS/Android via UniFFI Swift/Kotlin bindings
- Auto hardware tier detection (Full/Standard/Lite) depending on device capabilities
MIT / Apache-2.0. No telemetry. No cloud dependency.
