Google reportedly testing Gemini 4 'Carbon' checkpoint, said to rival Claude Opus 5.5 at coding
Google is internally testing a Gemini 4 checkpoint codenamed Carbon that one employee said feels comparable to Claude Opus 5.5 at coding.- For developers and enterprise coding users: Carbon is an internal Google checkpoint, not a released product — no API, pricing, benchmarks, or release date exist.
- Per Business Insider's review of internal documents and chats, Google is testing Gemini 4 variants named Argon, Barium, and Carbon; Carbon was deployed on Google's internal coding platform Jetski and beats Argon mainly on programming tasks.
- One employee compared Carbon's coding to Anthropic's Claude Opus 5.5 while cautioning more testing was needed; another called it the 'Gemini pro next model,' suggesting it may ship under the Argon name.
- Testers also report gains over Argon in 3D generation, spatial reasoning, and volume handling, though it is slower on some tasks; a broader rollout could come as early as November.
- The rapid iteration pace prompted DeepMind's Vedant Misra to point to 'recursive self-improvement' — using AI to build better AI — as a driver.
Chrome's enhanced autofill now uses Gemini to pull form info from Gmail
Google expanded Chrome's enhanced autofill to suggest form details sourced from users' Gmail via Gemini with Personal Intelligence.- For Chrome users filling out web forms, the feature now draws on Gmail content like flight confirmations, tracking info, and order details, with user permission.
- It builds on last year's enhanced autofill, which pulled names, passport numbers, email addresses, and addresses from Google Accounts and Google Wallet.
- The update deepens Gemini's integration into Chrome's everyday browsing and form-filling workflow.
- Permission-based access to inbox data raises the stakes for how Google handles personal context in browser AI features.

- GitHub Octoverse 2026: commits and merged PRs triple as agents reshape development
GitHub released its Octoverse 2026 report showing massive growth in developer activity attributed to agentic engineering.- GitHub's annual Octoverse report, announced at GitHub Universe 2026 by EVP Jay Parikh, tracks activity across GitHub's global developer base.
- Merged pull requests tripled in under a year to 220 million per month; commits more than tripled to 7.38 billion per month, with most growth in the second half of 2026.
- New repository creation doubled this year to 30.3 million per month.
- The report attributes the surge largely to agentic engineering — developers building with coding agents — and adds new breakdowns by industry and by repositories involving interoperability or reverse engineering, with a published methodology section.
- For developers and engineering leaders, the numbers signal that AI-assisted, agent-driven workflows are now the dominant driver of code activity on GitHub.
