    MCP tunnels is now available as a research preview, so you can connect to MCP servers in your private network

    Self-hosted sandboxes are now available for Claude Managed Agents, as an alternative to running tool execution in Anthropic’s infrastructure. With Claude Managed Agents, you can now update the agent’s MCP server and tool configurations associated with an active session. With Claude Managed Agents, large outputs from agent_toolset and MCP tools exceeding 100K characters (about 25K tokens) are now automatically spilled to a file in the sandbox.

    Released gemini-3.5-flash, the generally available (GA) version of Gemini 3.5 Flash, our most intelligent model for sustained frontier performance on agentic and coding tasks. This is now the model behind gemini-flash-latest. Launched the Managed Agents in the Gemini API in public preview. This enables developers to build and deploy autonomous, stateful agents that run in secure, isolated Google-hosted Linux sandbox environments. To learn more, see the Agents overview page and the Quickstart. Released the general-purpose Antigravity Agent managed agent, antigravity-preview-05-2026, in public preview. The Antigravity agent can autonomously plan, reason, write and execute code, manage files, and browse the web inside its sandbox container.

    Set speed: "fast" with model: "claude-opus-4-7" and the fast-mode-2026-02-01 beta header for significantly faster output token generation at premium pricing. Pricing, rate limits, and access are the same as for Opus 4.6 fast mode; interested customers should join the waitlist.

    Codex app

    Added an in-app trust review flow for hooks and kept Hooks settings reachable even before hooks are fully configured. Performance improvements and bug fixes. Restored tooltip-wrapped dropdowns that could stop opening after the tooltip rewrite. Preserved in-progress message edits across thread switches. Fixed several desktop workflow regressions, including Ctrl+V paste in the Windows terminal, opening modified external links outside the in-app browser, and keeping feedback slash commands attached to the right thread. Improved loading and panel polish by showing model loading while a thread resumes, hiding unavailable model controls during load, and bundling summary-panel layout and hover fixes. Kept the Computer Use settings control visible even when uninstalled and disabled problematic extension hover panels. Additional performance improvements and bug fixes.

Note: the default fresh changes EnterWorktree's base back to origin/ (it has been local HEAD since 2.1.128) — set worktree.baseRef: "head" to keep unpushed commits in new worktrees. Added sandbox.bwrapPath and sandbox.socatPath managed settings (Linux/WSL) to specify custom bubblewrap and socat binary locations.

  24. OpenAI · Codex app

    Codex for Chrome

    With the new extension for Chrome, Codex is even better at working with apps and websites in your browser.
