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.

GPT-5.6-Sol-Ultra is so good at maths that it created Minecraft clone in Lean (yes that Lean)

I burnt almost 50% of my Weekly usage in 8h Never felt more alive

I take it all back. We just got access to eval Grok 4.5 and it has landed above GPT-5.6-Sol and just shy of Opus for browser use. Because cache input is expensive, the overall cost is only 10% cheaper than opus. Its overall a bit faster. We have another opus-class model in the competition

we're seeing supersized results with muse spark 1, comparable to fable when generating static sites at a much lower cost
