Meet Context, the first AI office suite. Humanity spends 2.5 trillion hours a year on office work. Context can one-shot most of it. Welcome to the era of vibe-working. Sign up today or tag @contextsuite with a prompt.
The nature of AI compute demand is changing. Demand is consolidating with hyperscalers. Custom chips are becoming more competitive. Scaling increases returns to vertical integration. Distributed training will be the new norm. The Future of Compute: NVIDIA's Crown is Slipping…
Thrilled to share that I’ve joined @reflection_ai! We’re building superintelligent autonomous systems by co-designing research and product. Today, we’re launching Asimov. As AI benchmarks saturate, evaluation will increasingly live inside real-world products that are…
Engineers spend 70% of their time understanding code, not writing it. That’s why we built Asimov at @reflection_ai. The best-in-class code research agent, built for teams and organizations.

You can staple AI to existing productivity tools. But like any other technical revolution, applications built natively to harness and exploit them dominate. Excited to team up with @josephsemrai and his stellar team at Context Autopilot: tomorrow’s AI-native productivity…
Last year, we invested in Cognichip: what we expect to be a generational semiconductor company by making chip design as simple and accessible as vibe coding. They came out of stealth today with a vision for how we will design chips in the future:
Human Behavior (@humanbehaviorai) is building an AI that watches actual customers using your product, through session replays, to help you understand why they stay, convert, or leave. ycombinator.com/launches/NU8-h… Congrats on the launch, @OfficialAmogh, @skyguy_skyguy, and…
Willow (@WillowVoiceAI) is the future of voice-first computing. Thousands of people have replaced their keyboards with Willow to get emails, docs, and AI prompting workflows done 4x faster. Congrats on the launch, @_allanguo and @LiuLawrence45!
Mercor is solving global labor matching with models that understand human ability. @mercor_ai raised a $30M Series A at a $250M valuation, led by @victoralazarte and @bgurley at @benchmark, with participation from @peterthiel, @jack, @adamdangelo, and @LHSummers.
Today is a bad, bad day to be a language model. Today, we announce the Haize Labs manifesto. @haizelabs haizes (automatically red-teams) AI systems to preemptively discover and eliminate any failure mode We showcase below one particular application of haizing: jailbreaking the…
Introducing Gatekeep, the text-to-video AI that transforms your questions into engaging educational explainer videos. Now available on web and Discord. Get started at gatekeep.ai
Excited to announce that Mercor matched over 500 people with jobs in the last month alone, supplying talent to leading AI labs. forbes.com/sites/johnwern…
