Introducing upgrades to Codex
OpenAI has announced upgrades to Codex, its AI coding agent, improving speed, reliability, and real-time collaboration capabilities. The updates extend Codex's reach across multiple development environments including terminal, IDE, web, and mobile. The announcement emphasizes both interactive collaboration and autonomous task execution.
Claude Code 2.0: VS Code Extension, Checkpoints, and Agent SDK for Autonomous Development
Anthropic has released several major upgrades to Claude Code, including a native VS Code extension in beta, a refreshed terminal interface (version 2.0), and a checkpointing system that saves code state before each change to enable safe autonomous operation. The release also formalizes the Claude Agent SDK (formerly Claude Code SDK) with support for subagents, hooks, and background tasks, enabling parallel and long-running development workflows. Claude Sonnet 4.5 is now the default model powering Claude Code. These features collectively position Claude Code as a more capable autonomous coding agent for complex, multi-step software development tasks.
Codex for (almost) everything: OpenAI expands Codex app with computer use, browsing, image generation, memory, and plugins
OpenAI has updated its Codex desktop application for macOS and Windows with a broad set of new capabilities including computer use, in-app browsing, image generation, persistent memory, and plugin support. The update positions Codex as a more comprehensive agentic developer tool rather than a pure code-completion assistant. These additions bring Codex closer to a general-purpose AI agent environment targeting developer workflows.

It runs entirely locally, positioning itself as an efficiency layer between codebases and LLM-based coding assistants. The project gained significant traction with 3,688 stars in a single day, reaching 16,371 total stars.
Anthropic Releases Claude Sonnet 4.5: Top Coding and Computer-Use Model with Agent SDK
Anthropic has released Claude Sonnet 4.5, claiming it is the best coding model and strongest model for building complex agents, with a 61.4% score on OSWorld (up from 42.2% for Sonnet 4) and state-of-the-art performance on SWE-bench Verified. The release is accompanied by major product upgrades including checkpoints in Claude Code, a native VS Code extension, a Claude Agent SDK giving developers access to the same infrastructure powering Claude Code, and new context editing and memory tools in the Claude API. Pricing is unchanged from Sonnet 4 at $3/$15 per million input/output tokens. Early enterprise customers including Cursor, GitHub Copilot, Devin, Canva, and Figma report significant gains in coding, agentic, and long-context tasks.
Introducing the Codex App for macOS
OpenAI has launched the Codex app for macOS, positioning it as a command center for AI-assisted software development. The app supports multiple simultaneous agents, parallel workflows, and long-running coding tasks. This represents OpenAI's push into dedicated developer tooling beyond the ChatGPT and API interfaces.
