Added thread coordination for local projects and worktrees, including separate background threads when explicitly requested. Expanded search for past Codex app threads to include conversation content and Git branch names. Added stable identicons for background subagents across the app. Improved keyboard shortcut settings with keypress search and a reset-all action. Improved Chrome context capture for Google Docs, Sheets, and Slides tabs. Performance improvements and bug fixes. Additional performance improvements and bug fixes.

  6. Anthropic · Claude API

    We’ve launched mid-conversation system messages

    On Claude Opus 4.8, you can send role: "system" messages after a user turn (subject to placement rules) in the messages array, preserving prompt cache hits when instructions change during a long-running session. No beta header is required. The stop_details field on refusal responses is now publicly documented; it returns a category (cyber, bio, or null) and a human-readable explanation, so your application can route different classes of refusal to the right next step. On Claude Opus 4.8, the effort parameter defaults to high across all surfaces, including Claude Code and the Messages API. On Claude Opus 4.8, the minimum cacheable prompt length for prompt caching is 1,024 tokens, lower than on Claude Opus 4.7. With adaptive thinking enabled, Claude Opus 4.8 triggers reasoning only when a turn needs it, reducing wasted thinking tokens compared to Claude Opus 4.7 at the same effort level. Claude Opus 4.8 supports high-resolution image input (up to 2576 pixels on the long edge), same as Claude Opus 4.7. Task budgets now support Claude Opus 4.8. The advisor tool now supports Claude Opus 4.8. Computer use now supports Claude Opus 4.8. Fast mode for Claude Opus 4.8 is available as a research preview on the Claude API only. Setting the sampling parameters temperature, top_p, or top_k to a non-default value returns a 400 error on Claude Opus 4.8, same as on Claude Opus 4.7. In Claude Code, we’ve expanded Auto mode to more users for long-running tasks. In Claude Code, Max plan users now default to fast mode on Claude Opus 4.8. In Claude Code, Workflows are available as a research preview, letting you define and run multistep agentic plans. We’ve deprecated fast mode for Claude Opus 4.6, with removal approximately 30 days after launch. For updates to claude.ai, Cowork, Claude for Microsoft 365, and other Claude apps in this release, see the release notes for Claude Apps.

    Claude Opus 4.8 launch, plus 1 more change

    We’ve upgraded Claude Opus to a new version. Claude Opus 4.8 shows improvements over Opus 4.7 in coding, agentic skills, reasoning, and practical knowledge work tasks. We added connector permissions to extend the existing custom roles framework and allow administrators to control which connectors, and which individual tools on those connectors, are available to each custom role.

  8. Anthropic · New modelAnnouncement

    New model: Claude Opus 4.8

    We’ve launched Claude Opus 4.8 (claude-opus-4-8), our most capable model. Claude Opus 4.8 supports a 1M token context window by default on the Claude API, Amazon Bedrock, Google Cloud, and Microsoft Foundry, 128k max output tokens, and the same set of tools and platform features as Claude Opus 4.7.

    Pinned background sessions (Ctrl+T in claude agents) now stay alive when idle, are restarted in place to apply Claude Code updates, and are shed under memory pressure only after non-pinned sessions. Renamed /simplify to /code-review. It now reports correctness bugs at a chosen effort level (e.g., /code-review high); pass --comment to post findings as inline GitHub PR comments. The old cleanup-and-fix behavior has been removed.

    Claude now works with more security and compliance tools

    We introduced Claude Compliance API integrations with notable security and compliance tools. Now IT and security teams can govern Claude across our platform and suite of products, the same way they govern other applications in their stack. Learn how to get started with Claude Compliance API integrations.

  26. OpenAI · Codex app

    Appshots, goal mode, and more

    Appshots are now available in the Codex app on macOS. Press both Command keys to send the frontmost app window to Codex with a screenshot and available text, so Codex can work from context in another app without you copying, pasting, or describing it manually. This launch also includes: Goal mode is no longer an experimental feature and is available in the Codex app, IDE extension, and CLI. With Goal mode, you can have Codex drive toward a specific objective for hours or even days. Remote computer use, so Codex can use desktop apps after your Mac locks, including remotely via Codex Mobile. Codex scopes locked use to active, trusted computer use turns and includes safeguards such as short-lived authorization, covered displays, relock on local input, and manual-unlock fallback. Plugin sharing through marketplace sources is available for ChatGPT Business. Enterprise support is coming soon. Teams can distribute reusable plugin bundles that include skills, MCP servers, and lifecycle hooks. Advanced in-app browser annotations let you tweak styling such as font size, colors, and spacing directly using annotations. This gives Codex a clearer signal for changes. Browser-use improvements across in-app browser & Chrome: Codex can now download and extract all image assets from a page much more quickly. Codex can now extract structured data from pages more effectively and find information more quickly with a read-only JS sandbox. Chrome extension will create less clutter when using it. Codex will no longer create tab groups when taking over existing tabs, and at the end of a task for handoff. Instead, it uses tab icons to indicate status. Significantly improved reliability for browser use. We fixed bugs on Windows, flaky availability of the plugin to non geo-blocked regions, and many other issues impacting performance.
