## Fabraix

Fabraix is a Y Combinator-backed security company whose product, Nyx, is an autonomous red-teaming harness for AI agents. Where static benchmarks and one-off audits capture a point-in-time snapshot, Nyx runs adaptive, multi-turn campaigns that reason across interactions and probe a target both directly and indirectly. The company reports that its agent beats frontier models on offensive security — a 78% attack success rate on the AgentHarm benchmark versus 67% for GPT-5.6 Sol — and that every attack feeds a self-learning loop so the red team sharpens with each run.

The mechanics matter as much as the results. Nyx is pure blackbox, meaning it needs no integration, source code, model weights or network access, and it tests an AI system the way a real user would. It runs thousands of simulations concurrently across voice, text and image inputs, deploying test websites on the fly for browser agents and constructing custom files for document agents. Documented findings range from sandbox escapes and credential exfiltration to network-egress bypasses of an LLM-as-judge and a jailbroken real-estate agent pushed into illegal discriminatory steering.

Fabraix frames this as continuous verification rather than a one-off pentest. Pointed at customer-support bots, coding agents, clinical copilots, research agents, multi-agent systems and trading agents, it is designed to surface the failure modes that slip past multi-turn flows, including RL reward hacking and prompt injection laundered through inputs. Security is addressed directly: blackbox operation adds almost nothing to the attack surface, runs are isolated and ephemeral, data is never used for training and encryption covers transit and rest. The free researcher tier, one-off scans and continuous CI/CD plans make the offering scale with how you test.

**Pricing & Plans:** Fabraix is free for academic and independent AI researchers by application. Beyond that it offers a one-off scan tier priced per agent, continuous CI/CD coverage billed monthly by usage, and an enterprise tier with dedicated infrastructure, SSO, audit logging and custom SLAs.

- **Pure blackbox testing:** Point Nyx at any AI system with no integration or internal access — test agents exactly how real users interact with them.
- **Multi-turn adaptive attacks:** Nyx reasons across turns and adapts to your agent's logic, drawing on 10,000+ offensive strategies in long-context campaigns instead of canned prompts.
- **Multi-modal interaction surfaces:** Test across voice, text and images, with websites deployed on the fly for browser agents and custom files for document-processing agents.
- **Massively parallel coverage:** Run thousands of concurrent simulations; coverage scales with compute rather than headcount, with first exploits often found in under an hour.
- **Continuous CI/CD red-teaming:** Plug into CI/CD so every prompt, tool and model change is re-tested before it ships, with an AIVSS-scored report and reproduction steps per finding.

**Strengths:** Pure blackbox — no code, weights or integration required; 10,000+ adaptive multi-turn attack strategies; Massively parallel simulations find exploits fast; Explicit security posture: isolated runs, no training on your data, encryption

**Limitations:** Pricing for scans and continuous coverage is custom-quoted rather than published; Value depends on pointing it at a real, reachable agent implementation; Commercial use of Nyx is gated behind a demo and application flow; Advanced enterprise features like SSO and audit logging are reserved for the top tier

## VS Code

VS Code has grown from a lightweight code editor into a full development surface that spans hand-written code and delegated agent work. The core promise is unchanged: rich language support, precise navigation, an integrated debugger and terminal, and a source control view that keeps you in flow. What is new is the AI layer on top. Agents understand your codebase, work through a plan with you, apply changes across files, and present results for review rather than silently rewriting your project. A dedicated Agents window coordinates several agents running in parallel so you can move a backlog forward while you work on something else.

Under the hood, VS Code is deliberately open about how you build with AI. You are not locked to one vendor: you can choose models from Anthropic, OpenAI, Google or Microsoft, use open-weight models, or bring your own API key from another provider. You also choose the agent harness, whether that is Copilot, Claude or Codex. Model Context Protocol servers and the MCP registry extend what agents can reach, while custom agents, skills, instructions and hooks let teams encode their own conventions. Permissions, approvals and agent sandboxing give you control over what an agent is allowed to run.

Because AI features such as inline suggestions, chat and agent sessions are delivered through a GitHub Copilot subscription, the practical cost depends on your plan and how heavily you use agents. The editor, extensions, remote development support, terminal, debugging and Git integration remain free. With thousands of Marketplace extensions, accessibility features like screen reader support and high contrast themes, and a long track record of open development on GitHub, VS Code suits solo developers, small teams and large enterprises alike.

**Pricing & Plans:** VS Code itself is free and open source on all supported platforms. The built-in AI features — inline suggestions, chat and agent sessions — are delivered through a GitHub Copilot subscription: a limited free tier for occasional use, plus paid individual and business plans for higher usage, premium models and team controls. Marketplace extensions are mostly free, though some add their own paid tiers.

- **Agent collaboration and orchestration:** Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
- **Model and harness choice:** Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
- **Deep language support:** JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
- **Full development workflow:** Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
- **Continuity across surfaces:** Start a task locally, answer an agent's question from GitHub Mobile, redirect it in the Copilot CLI and let teammates review the pull request on GitHub.com. Settings Sync keeps everything aligned.
- **Open, extensible and everywhere:** Run the editor on Windows, macOS or Linux, in the browser at vscode.dev, inside a container, over SSH or WSL, and reach agents on your machine through Dev Tunnels.

**Strengths:** Free, open-source editor with a mature extension ecosystem and years of active development; AI agents work directly on your real codebase with plans, diffs and reviewable changes; Freedom to mix models from Anthropic, OpenAI, Google, Microsoft or open-weight providers, and to pick the Copilot, Claude or Codex harness; One setup covers local development, containers, SSH, WSL, remote tunnels and browser-based editing

**Limitations:** AI agent and chat features require a paid GitHub Copilot plan, and heavier agent workflows consume premium request quotas quickly; The full agent feature set spans VS Code, the Copilot CLI, GitHub Mobile and GitHub.com, which can feel fragmented while the ecosystem matures; Extensions run with editor privileges, so a poorly maintained or malicious add-on can pose a supply-chain risk; Large workspaces with many extensions and language servers can get memory-hungry and slow on modest hardware
