Reflection is partnering with Shinsegae Group to build a 250-megawatt sovereign AI factory for the Republic of Korea.

Open intelligence. Built on trust between allies. Owned by the nations that need it most.

The future of sovereign AI. Read more in the @WSJ.

[Becky Sosnov @BeckySalman]

Marked today's partnership between @reflection_ai and Shinsegae with a signing at the Department of Commerce's National AI Center opening with Secretary @howardlutnick - a fitting backdrop 🇺🇸🇰🇷

[Aakanksha Chowdhery @achowdhery]

Building open intelligence matters because it democratizes the model weights for all and they can be inspected as well as customized independently.

Today Reflection is proud to share that its partnership with Shinsegae Group to build a 250-megawatt AI factory for South Korea; sovereign AI infrastructure that Korean government and enterprises can own, control, and build on. This partnership is that belief made real.

Excited for what's ahead.

Ten years ago, AlphaGo’s legendary match in Seoul heralded the start of the modern era in AI. Its famous ‘Move 37’ signaled to us that AI techniques were ready to tackle real-world problems in areas like science - and ideas inspired by these methods are critical to building AGI

[Ashlee Vance @ashleevance]

.@MishaLaskin and @reflection_ai have raised $2 billion to build America's next top open source AI model.

This week Misha comes on the pod to talk DeepSeek, open weights and AI freedom for all

Thanks, as always, to @brexHQ and @e1ventures for backing the @corememory pod

[Ioannis Antonoglou @real_ioannis]

Really excited to have you join @Skiminok , looking forward to working closely together

[🇺🇦 Alex Polozov @Skiminok]

🎉 Next week, I am excited to join @reflection_ai as a Member of Technical Staff to help build the open intelligence ecosystem of the Western world.

It's the most exciting opportunity to help software builders in our time, and will shape many years of AI Engineering in the medium-term before AGI. Not just about Western vs Eastern open models, but more about how AI-driven software will look like in 2030.

I spent some time articulating my thoughts about where we're going as a community and why... which became a whole blog post. Take a look, hope it interests you!
(And if it really does, we are hiring in NYC, SF, and London 😉)

We're bringing the open-model frontier back to the U.S. to advance the science and engineering of agentic intelligence for the world.

Grateful to our investors for powering this vision: NVIDIA, Disruptive, DST, 1789, B Capital, Lightspeed, GIC, Eric Yuan, Eric Schmidt, Citi, Sequoia, CRV, and others.

[Reflection @reflection_ai]

Today we're sharing the next phase of Reflection.

We're building frontier open intelligence accessible to all.

We've assembled an extraordinary AI team, built a frontier LLM training stack, and raised $2 billion.

Why Open Intelligence Matters

Technological and scientific progress is driven by values of openness and collaboration.

The internet, Linux, and the protocols and standards that underpin modern computing are all open. This isn't a coincidence. Open software is what gets forked, customized, and embedded into systems worldwide. It's what universities teach, what startups build on, what enterprises deploy.

Open science enables others to learn from the results, be inspired by them, interrogate them, and build upon them in order to push the frontier of human knowledge and scientific advancement. AI got to where it is today through scaling ideas (e.g. self-attention, next token prediction, reinforcement learning) that were shared and published openly.

Now AI is becoming the technology layer that everything else runs on top of. The systems that accelerate scientific research, enhance education, optimize energy usage, supercharge medical diagnoses, and run supply chains will all be built on AI infrastructure.

But the frontier is currently concentrated in closed labs. If this continues, a handful of entities will control the capital, compute, and talent required to build AI, creating a runaway dynamic that locks everyone else out. There's a narrow window to change this trajectory. We need to build open models so capable that they become the obvious choice for users and developers worldwide, ensuring the foundation of intelligence remains open and accessible rather than controlled by a few.

What We've Built

Over the last year, we've been preparing for this mission.

We’ve assembled a team who have pioneered breakthroughs including PaLM, Gemini, AlphaGo, AlphaCode, AlphaProof, and contributed to ChatGPT and Character AI, among many others.

We built something once thought possible only inside the world’s top labs: a large-scale LLM and reinforcement learning platform capable of training massive Mixture-of-Experts (MoEs) models at frontier scale. We saw the effectiveness of our approach first-hand when we applied it to the critical domain of autonomous coding. With this milestone unlocked, we're now bringing these methods to general agentic reasoning.

We've raised significant capital and identified a scalable commercial model that aligns with our open intelligence strategy, ensuring we can continue building and releasing frontier models sustainably. We are now scaling up to build open models that bring together large-scale pretraining and advanced reinforcement learning from the ground up.

Safety and Responsibility

Open intelligence also changes how we think about safety. It enables the broader community to participate in safety research and discourse, rather than leaving critical decisions to a few closed labs. Transparency allows independent researchers to identify risks, develop mitigations, and hold systems accountable in ways that closed development cannot.

But openness also requires confronting the challenges of capable models being widely accessible. We're investing in evaluations to assess capabilities and risks before release, security research to protect against misuse, and responsible deployment standards. We believe the answer to AI safety is not “security through obscurity” but rigorous science conducted in the open, where the global research community can contribute to solutions rather than a handful of companies making decisions behind closed doors.

Join Us

There is a window of opportunity today to build frontier open intelligence, but it is closing and this may be the last. If this mission resonates, join us.

[Misha Laskin @MishaLaskin]

Asimov is our first step toward superintelligence.

We believe comprehension is at the root of this problem.

Build with us.

Product: shape how teams use Asimov.
Research: develop powerful agentic models.

@MishaLaskin @reflection_ai Really exited to share what we have been building with the incredible team at @reflection_ai

[Misha Laskin @MishaLaskin]

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.

[WIRED @WIRED]

The mission? Teaching models to better understand how to build code will lead to superintelligent AI. https://t.co/kRdPSr6mS5

[Misha Laskin @MishaLaskin]

We look for colleagues who have high internal drive, integrity, and a deep interest in the problems we’re pursuing. If that’s exciting to you, join us.
