Most AI tools ask you to trade your data for intelligence. Norton Neo doesn't. It's the first safe AI-native browser built by Norton, and it gives you powerful built-in AI without handing your privacy over to get it. Search, summarize, and write with AI built directly into your browser. Your data stays yours. Your context stays private.
Built-in VPN, anti-fingerprinting, and ad blocking come standard. No add-ons. No setup. No compromises.
Fast. Safe. Intelligent. That's Neo.

With emerging trends in AI, machine learning, and big data, 2026 brings a new wave of data science tools designed to streamline workflows and enhance productivity. In this blog, we’ll explore the must-know data science tools that can help you stay competitive and advance your career in the ever-expanding data science landscape.

The ChatGPT maker just shipped major updates to its Agents SDK, giving enterprises a safer way to deploy automated helpers. A fresh sandbox integration isolates agents within controlled workspaces, limiting their access to only the files and code they need. The SDK also gains an in-distribution harness for frontier models, which should help tackle those complex, multi-step jobs that have proven notoriously tricky to automate.

We built it as a PR review agent on OpenClaw called Eagle Eye. It fetches a GitHub pull request, analyses the diff, and sends structured feedback directly to your Telegram chat. Reviews cover security vulnerabilities, bugs, code quality, and best practices, grouped by severity and rated overall. Nothing gets posted to GitHub without your explicit approval.

The frontend cloud platform just unveiled Open Agents, a template for deploying coding agents that run indefinitely in the cloud. Built with their AI SDK and Sandbox tools, it allows teams to run hundreds of agents at once with zero timeouts or setup hassle.
