Use Grok Voice models in LiveKit to build useful voice agents with full support for ZDR
LiveKit@livekit·We built a patient intake agent with @SpaceXAI that runs end to end on Grok voice models. Grok STT → Grok 4.3 → Grok TTS, cascaded through LiveKit Inference. Three model strings in one AgentSession. No separate API key, no separate billing, ZDR on every hop. Talk to it: t.co/hx4jvwaWLx
Grok Voice Think Fast 2.0 is now #1 on the Artificial Analysis Speech-to-Speech Index. This index measures whether voice agents can reason over the speech it hears, resolve real customer issues, and correctly complete tasks using agent tools.
At Starlink, we’re using Grok Voice to resolve over 15,000 inbound customer support and sales calls a day. Grok diagnoses hardware issues, ships replacements, and fulfills over 3,000 orders a week across voice calls and chat.

Welcome to the SpaceXAI team! Cursor will help us move faster on the path to the world's most useful AI, starting with software engineering and expanding into knowledge work.
Cursor@cursor_ai·Cursor is now part of @SpaceX. Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world's most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more. SpaceX has built some of the most inspiring and impressive technology in the world, and we’re grateful for the opportunity to become part of such a special company. Onwards.
Congratulations to the winners of the SpaceXAI Grokathon 2026. Here are the top 3 projects that were built in the 12 hours!

Now builders can create apps and sites, connect any frontend to Wix business services through Wix Headless, manage Wix business solutions, and work with Wix MCP, all from the Grok CLI. We are making it easier to build with Wix wherever developers are already creating. Builders, go build.
Introducing Grok 4.6. It delivers frontier intelligence and is a significant improvement over Grok 4.5 at the same price.
Grok 4.6 is faster than comparable models and can handle much more challenging tasks than Grok 4.5. It's half the price of other frontier models at $2/M input and $6/M output tokens.

Grok 4.5 at #2 on Proximal's FrontierSWE benchmark across implementation and performance, and #1 on research abilities x.com/ProximalHQ/sta…
We've open-sourced Grok Build and have reset usage limits for all users. Open sourcing Grok Build allows anyone to support making a reliable and robust harness. Check out our code, including the Git repo for the Grok Build CLI. x.ai/open-source
In response to user questions about privacy: Since launch, Grok Build has fully respected zero data retention (ZDR). All users have always had the ability to disable data upload in the CLI. When data upload was disabled, this choice was respected. In the early beta, data retention was enabled by default for non-ZDR users. Based on your feedback, we changed this. We are now going further to protect privacy. With all retained data deleted, retention default off, and an open-source harness, we are offering complete user privacy. You can also run Grok Build fully open-sourced and local-first with your own inference. We disabled default retention for all Grok Build users starting on July 12th. Additionally, we are deleting all coding data that was previously retained, ensuring every user’s preferences are respected. With these steps, Grok Build goes beyond other major coding products to protect user privacy.
We care deeply about your privacy and respect customer choice. For teams using zero data retention, no trace and code data is ever retained. All API key use of Grok Build also respects ZDR. If ZDR is disabled, the /privacy command is available in the CLI to disable data retention, which also deletes previously synced data. Run the /privacy command to view or change your settings at any time.
