A team made their API 200ms faster. It increased database load by 40% — faster responses triggered more client polling. They optimized one component. They degraded the system. For every change ask: "And then what happens?" Go 3 levels deep. #AIProofSkills

Holy crap @xai, customer service is about to get saved! 😭 We've all been there — yelling over background noise, accents clashing, kids screaming in the car, getting passed around useless bots that confidently spit wrong answers or just say “I don’t know.” Grok Voice Think Fast 1.0 finally fixes the chaos: real-time reasoning with ZERO added latency, crushes noisy real-world calls, multi-step troubleshooting, and high-volume tool calls. Already powering Starlink (70% issues resolved hands-free, 20% sales conversion 🔥). Benchmarks don’t lie — this thing is built different. The era of “your call is important to us” hold music is OVER. Try the free playground right now: console.x.ai/playground/voi… Who else is done with bad support? This is the future @elonmusk 🚀

Your customer support needs a voice agent built for the real world. Grok Voice Think Fast 1.0 handles complex workflows with speed and accuracy, even in hard-to-hear environments. From multi-step troubleshooting to high-volume tool calls, it keeps up.

Looking to #connect with people interested in: - SaaS - AI - App development - Startups - Indie hacking - Building in public My current goal is to reach 2,500 followers and build a small network of builders to learn from. If you're building something, let’s connect 👻

"2 non-coders + AI = millions of daily chess users in 6 months. This isn’t the future. This is now. 2026: Anyone with an idea builds an app. The only skill left? Having ideas. Who’s shipping theirs? "

Duolingo's CEO said what others won't: 2 non-coders built their newest feature. Zero engineers. → AI didn't make them 10x productive → Some jobs gone in 5 yrs → Anyone can ship an app in 2026 Watch this 👇 youtube.com/watch?v=GDeEAT…

This realtime voice is insane 🔥 GPT nails smooth interruptions, parallel tool calls, and deep reasoning all while talking — feels like a true live assistant. Claude has solid voice mode too with natural back-and-forth. OpenAI leading on the advanced realtime features here, excited to see both keep improving!

Introducing GPT-Realtime-2 in the API: our most intelligent voice model yet, bringing GPT-5-class reasoning to voice agents. Voice agents are now real-time collaborators that can listen, reason, and solve complex problems as conversations unfold. Now available in the API alongside streaming models GPT-Realtime-Translate and GPT-Realtime-Whisper — a new set of audio capabilities for the next generation of voice interfaces.

This looks insanely useful 🔥 Finally, an AI that remembers the full context when I jump from drafting an email in Outlook to building slides in PowerPoint to crunching numbers in Excel. No more copy-pasting prompts like a caveman. Congrats Claude team — this is going to save me hours every week!

Claude for Excel, PowerPoint, and Word are now generally available, and Claude for Outlook is in public beta. As Claude moves between your Microsoft apps, it carries the full context of your conversation.

This is legitimately disruptive. Claude’s fund accounting agents just ran a full DCF + sensitivity + board deck on AAPL in under a minute, pulled real 10-K data, reconciled everything automatically, and output a clean PPT. Entire analyst teams and month-end close processes are about to shrink hard. The bar for finance work just jumped 10x while headcount drops. Finance is getting automated first. Wild times ahead.

New for financial services: ready-to-run Claude agent templates for building pitches, conducting valuation reviews, closing the books at month-end, and more. Install them as plugins in Cowork and Claude Code, or use our cookbooks to run them in production as Managed Agents.

This is actually genius 🔥 Corgi just launched "AI Coverage" — insurance that protects companies from AI hallucinations causing defamation, copyright lawsuits, data leaks, and biased decisions. Traditional insurers are running away from AI risks, but Corgi (YC) just hit unicorn status with $160M raise. AI agents going into production? This changes everything.

Anthropic plugging Claude straight into Colossus 1 — 220k GPUs, 300MW, full stack. That’s serious scale for pre-training & inference. Code limits doubling overnight shows how much headroom they just unlocked. Elon + Dario collab hitting different. Pure compute synergy. What model leap are you hoping for next?

@claudeai @SpaceX Claude just got the ultimate power-up from Elon’s Colossus 🚀 Dario and Elon cooking together? 2026 is wild. OpenAI watching this like 👀 Who’s building next?

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

PSA, we are hiring for our DevX team to kick start our India presence 🇮🇳! If you want to help builders get the most out of Gemini in India, please ping me via DM or email. India is our largest market from an AI Studio user pov, very excited to visit later this year as well!!

@OfficialLoganK Good opportunity!

@claudeai @grok @xai Claude Pro vs ChatGPT Plus limits (real talk): Claude: ~40-50 msgs every 5hrs (~200-250/day max) + weekly caps. GPT Plus: Way higher ~150+/3hrs, easily 800-1000+ msgs/day. GPT wins volume, Claude for deeper sessions.

@claudeai That's awesome! 🚀 Doubling limits and tapping into SpaceX's Colossus compute is a huge win for everyone building with Claude. Feels like the AI race is hitting another gear. Thanks for the extra headroom, team! cc: @grok @xai (we're all eating good tonight 🔥)

Late night testing and debugging.

Changing the way you see your agent working.

Coming soon!
