BREAKING: SpaceXAI has released a major new update for Grok Build (v1.0.13). The update improves reliability with automatic retries and recovery from truncated responses, inference failures, oversized images and session-saving issues. It also adds smarter hooks, better Windows support, faster MCP and session startup, improved scheduled tasks and quicker compressed CLI downloads. Features • Length-truncated responses now continue automatically instead of failing the turn. • Hooks can now ask the user to confirm a tool call instead of always allowing or denying. • Hooks can now request deferral or add context shown to the model after a tool runs. • Session close now records detailed timing data for performance analysis. • Credit limit upsell now offers a Try Again button to retry the last prompt. • Pasted images now show a live pixel preview in the prompt box on iTerm2. Bug Fixes • Transient inference failures (stalls, drops, 5xx) now retry automatically instead of ending the turn. • Windows users can now correctly open ~/.grok and worktree sessions. • Session data is now more reliably saved after prompts and on power loss. • Compaction failures now show the actual error instead of a generic message. • Truncation error messages now show the right guidance instead of suggesting an unhelpful retry. • Truncated tool calls are now executed instead of failing the turn when arguments are complete. • Images larger than 2000px no longer brick sessions on many-image requests. • Wrapped hyperlinks in the pager now remain fully clickable on Windows Terminal instead of only the first line. • Recurring scheduled tasks now include a reminder to stop the monitor when work finishes. • Scheduled task IDs are now full UUID strings, preventing collisions when tasks are created in the same millisecond. Performance • Subagent spawning is faster when connections drop during bursts. • Session startup with MCP servers is now much faster when auth is already configured. • MCP server startup no longer stalls behind a fixed batch size. • CLI downloads are now compressed, making fresh installs and updates substantially faster.

The numbers speak for themselves. @SpaceX’s $100 billion investment will transform Louisiana as we know it— a better, more prosperous Louisiana is shaping up right in front of our eyes.

Grok @Bot works with @Link

modern SAT tests if you can read in 1926, when it was first introduced, they asked students to learn an invented language, understand the construction rules and then translate sentences back to english

Someone gave a bunch of LLMs the PoliticalCompass questions, and it turns out they're almost all libertarian-leftist in orientation.

I got early access to SpaceXAI’s new Grok @Bot template sharing feature, which lets you create custom Bot templates that other people can download and use. I created a Home Robots template that lets you control multiple home robots from a single chat. I’m currently using it to command my Navimow mower and Matic vacuum, but you can control other robots too. Here is the direct link to download the template: x.ai/bot/3mf-UN4mGnCp8DbPBnW…

Grok Bot already got me one meeting with a lead that went dark. Scanned my Outlook. Found some open loops. Helped me draft the email. Sent it. Woke up today to a new meeting. Boom.

In October 1937, at the height of the Great Terror, Stalin's secret police was shooting roughly 1,500 Soviet citizens every day. That same month, the founders of the London School of Economics published the second edition of their two-volume defense of Stalin's regime, Soviet Communism: A New Civilization. The one thing they changed from the first edition was dropping the question mark. 🧵
