    Create Codex access tokens

    ChatGPT Enterprise workspace owners and admins can allow permitted members to create Codex access tokens for trusted, non-interactive Codex local workflows. Members can use access tokens to run Codex from scripts, schedulers, and private CI runners with their ChatGPT workspace identity. Learn more in Access tokens.

    Added dictation cleanup plus a configurable dictation dictionary for names, file paths, and code symbols. Added zoom and download controls to the image lightbox. Performance improvements and bug fixes. Improved voice and dictation error messages for microphone, connection, and quota failures. Fixed in-app browser comment markers so they stay aligned across scrolling, zoom, and responsive layout changes. Made pull request creation and recovery flows more reliable by preserving newly created pull request state, classifying more app-server failures as restart-required, and stopping exhausted remote reconnect loops. Additional performance improvements and bug fixes.

    Updated File Search to support multimodal search. You can now natively embed and search through images using the gemini-embedding-2 model. Grounding metadata now includes media_id for visual citations and page_numbers that indicate where information is found. To learn more, see the File Search guide.

    Bare /color (no args) now picks a random session color. /mcp now shows the tool count for connected servers and flags servers that connected with 0 tools.

    We’ve launched Workload Identity Federation

    Authenticate workloads to the Claude API with short-lived OIDC tokens from your own identity provider (AWS IAM, Google Cloud, GitHub Actions, Kubernetes, Microsoft Entra ID, Okta, SPIFFE, and more) instead of long-lived static API keys. Configure issuers and federation rules in the Claude Console, and the SDK handles token exchange and refresh automatically.

    The /model picker now lists models from your gateway's /v1/models endpoint when ANTHROPIC_BASE_URL points at an Anthropic-compatible gateway. - Added claude project purge [path] to delete all Claude Code state for a project (transcripts, tasks, file history, config entry) — supports --dry-run, -y/--yes, -i/--interactive, and --all.

  12. xAI · Grok API

    Context Compaction

    The Context Compaction API is now available. You can shrink long conversations into a shorter context and reuse it in follow-up requests for lower cost, faster time-to-first-token, and sharper responses on long agent loops.

  13. xAI · Grok APIAnnouncement

    Custom Voices

    You can now clone a voice from a short audio clip and use it across the Text-to-Speech and Speech to Speech APIs. Create and manage your voice catalog from the SpaceXSI console.

  14. xAI · Grok API

    Grok Build

    Grok Build is now available in beta. Use the interactive TUI, run headlessly in scripts, or build apps and orchestrators with the Agent Client Protocol. Install with a single command: bash customLanguage="bash" curl -fsSL https://x.ai/cli/install.sh | bash For more details, see the Grok Build docs.

  15. xAI · Grok API

    Image Search in Web Search

    Web Search now supports explicitly searching for images. Enable enable_image_search to let Grok search directly for relevant images; responses can include returned images as Markdown image embeds. For details, see Enable Image Search.

  16. xAI · Grok API

    Smart Turn for Streaming STT

    The streaming Speech to Text API now supports Smart Turn end-of-turn detection. When enabled via the smart_turn query parameter, an ML model predicts whether the speaker has finished their thought at silence boundaries — reducing false endpointing during dictation, number sequences, and mid-sentence pauses. Use smart_turn_timeout to set a maximum silence fallback.

  17. xAI · Grok API

    WebSocket Responses API Mode

    WebSocket Responses API mode is now available. Drive the Responses API over a single, long-lived WebSocket connection for lower end-to-end latency on tool-heavy agent workloads.

    We’ve retired the 1M token context window beta for Claude Sonnet 4.5 and Claude Sonnet 4

    The beta header now has no effect on these models, and requests exceeding the standard 200k-token context window return an error. To use the 1M context window, migrate to Claude Sonnet 4.6 or Claude Opus 4.6, where it’s included at standard pricing with no beta header required.

    Added a tooltip on realtime delegation messages to clarify that Codex uses the surrounding voice conversation as context. Performance improvements and bug fixes. Fixed search in long review files so next and previous results reliably jump to off-screen matches. Kept embedded MCP app panels from restarting or losing state during fullscreen changes and thread reloads. Fixed several desktop regressions, including tray crashes when the local connection is missing, duplicate macOS fullscreen menu entries, and broken global dictation hotkeys on older macOS versions. Additional performance improvements and bug fixes.
