“Great work by the @xAI team! [@xai] Today, we're excited to launch the Grok Voice Agent API, empowering developers to build voice agents that speak dozens of languages, call tools, and search realtime data. https://x.ai/news/grok-voice-agent-api”

“And Grok Code is improving every week [@amXFreeze] A month since the release of Grok Code and it’s STILL the most-used AI coding model out there Grok Code stands alone as the #1 coding agent breaking record usage across OpenRouter and Kilo Code, with leading adoption no competitor can match Grok Cade Fast 1 is the fastest, most”

“Grok [@cb_doge] BREAKING: Grok just got a major upgrade. Grok-4-Fast got a big boost. Massive jump in reasoning quality and completion rate. • Reasoning mode: 77.5% → 94.1% • Non-reasoning: 77.9% → 97.9% Grok just got a whole lot smarter. Great work xAI team.”

“2M context window! [@tetsuoai] Grok 4 Fast is available in the xAI API. 💫 2M context window!”

“Just tap the xAI/Grok button to explain anything”

“Grok upgrades [@xlr8harder] Someone from xAI reached out and asked me to retest grok-4-fast, because they've improved the injected system prompts.

“All you need to know to understand which company will win a technology competition is look at the first and second derivatives of the rate of innovation [@Scobleizer] Grok 3 benchmarks. The thing to really pay attention to in AI is learning speed. And @xai is learning way faster than any other. Who said that? Apple Siri cofounder Tom Gruber. He told me at dinner a decade ago that that is the most important thing to pay attention to. )”

“And Grok is improving faster [@bycloudai] the grok-3 benchmark is pretty useful in comparing base models, so I added GPT-4.5 )”

“Btw, Grok 2 is still being used to explain 𝕏 posts. That will update to Grok 3 in a day or two. [@iamgingertrash] Final Verdict: Grok 3 > R1 > O1 pro > Sonnet 3.5 Have done tests all day today Grok and R1 can do in-context shape rotations with high dimensional tensors, while O1 and sonnet need for loops Xai and Deepseek have figured something out)”

“Critical feedback about Grok is super helpful. We will keep iterating until Grok is the best in every way. [@cb_doge] You can share quick feedback while using Grok to help the xAI team make it better. If you like a reply, tap the thumbs up icon.
