The best way to build safe AI, is secure the risks it creates with defensive capabilities faster than they can proliferate.

As we enter an accelerated era of capability, the AI security mission is incredibly important to me. Grateful to be working with Cathedral on the cybersecurity side with @Lux_Capital.

As AI becomes more capable at finding vulnerabilities, defenders need to put it to work before attackers do.

We’re planning our next internal security sprint at OpenAI and partnering with Cathedral Systems, whose researchers will use our models alongside our teams to challenge our defenses. They’ll bring differentiated expertise and approaches to our ongoing work to find and fix weaknesses with AI.

We’re also raising bug bounty rewards, including more than quadrupling rewards for critical findings. Exceptional findings will be eligible for up to $172,000, including bonuses.

We’ll keep advancing our models, using them to strengthen our own systems, and expanding access for trusted defenders.

AI should help us make more things.

Mark (@_markelliot) and Ben (@bbavardage) are legends at Palantir.

I worked closely with Ben in the early days of Valthos while they were getting Lumaril started. His reputation is deserved.

Honored for @Lux_Capital to co-lead the seed!
Lumaril @lumaril Oct 27
Today we’re launching Lumaril.

We’re an industrial autonomy company helping America’s existing factories run at their true capacity, with more production and less waste.

The US is home to hundreds of thousands of plants, run by senior operators with decades of tacit knowledge. Much of it is unwritten, and a growing wave of retirements is taking it out the door.

If we let these facilities go dark, we don't just lose great companies and the towns that depend on them. We lose the living blueprints for making the goods and materials this country can’t afford to do without.

Reindustrialization won’t come from new factories alone. The plants we already have are great American businesses, built over generations, with enormous potential to grow. We believe helping them scale is the fastest path to restoring industrial capacity.

Honored to deepen our partnership with the Flappy family, and for @Lux_Capital to co-lead this next chapter in unlocking radical breakthroughs in efficiency of intelligence.

It has been a pleasure getting to know @spectorb @amspector100 & @aidanmantine more deeply, and witnessing them continue to raise their level of ambition every time we meet.

We’ve spent the past year developing new primitives for GPUs. We believe this enables new algorithms to change how machines learn, open new markets, and dramatically reshape AI’s cost structure.

We have raised a $1 billion Series A, co-led by Index and Lux.

Congrats @jaimalik Lux family co @AmcaInc & @USArmy on teaming up to strengthening our capacity for critical components.
Amca @AmcaInc Oct 8
Amca has been awarded a contract by the @USArmy, establishing an enterprise-wide partnership with Army Materiel Command for rapid engineering, qualification, and component production.

This is the first partnership of its kind, designed to increase readiness for a priority missile system by re-engineering and improving manufacturability of critical components and subsystems.

We're grateful for the Army’s trust, urgency, and leadership, and look forward to re-engineering American industry together.
