What Google Announced
According to the official Google blog, Google announced on October 13, 2026 that developers could build with Gemini 4 Argon starting that day. Google calls it its frontier model, meaning the company's most advanced AI model, for handling complex workflows such as real-world software engineering, enterprise knowledge work and cybersecurity defense.
Google says Gemini 4 Argon is designed for long-horizon workflows that require deep reasoning and structural precision, meaning tasks with many steps that take a long time to finish, including code migration (moving existing code to a different architecture or technology) and frontier research. Google also says the model handles multi-step problems so developers can focus on building and shipping products. These descriptions are Google's own.
How Developers Can Get Access
Google says developers can get started with the paid tier of the Gemini API; an API is the interface that lets a developer's programs call the model directly, and the paid tier is the plan that requires payment. Google AI Ultra subscribers can try it in Google AI Studio and Google Antigravity. Google describes Antigravity as its agent-first development platform, where an "agent" is an AI program that can carry out multi-step tasks on its own.

GitHub Secret Scanning Adopts a New Classifier That Uses Context to Tell Real Secrets from Lookalikes; GitHub Says False Positives Fall and Scans Get Faster
GitHub says secret scanning, the feature that finds credentials such as passwords and keys in code, now uses a two-stage flow: rules find candidates, then a small AI model judges them. By GitHub's own account, developers and security teams will see fewer false positives, faster scans and lower cost, and generic secrets can be caught before code is pushed.
