We brought back data services today. Wild to think that we had these down for nearly 2 weeks. Even wilder the number of PRs the team merged in order to rearchitect this for the future of cybersecurity. Hint, it was 900.
Sending support to the security and leadership teams that are containing agentic attacks. Take care of your ppl. Prioritize your customers. In that order. Everything else will work out.
Our team has confidence that we contained this incident as of yesterday. Today we start the process of bringing systems back online for our customers. This is by no means a convenient decision but one we feel is necessary for the good of our customers. But damn..will we come back stronger than ever 💪🏽
We identified a security incident involved unauthorized access to user credentials on the @LightningAI Studios Platform. While we investigate, the Platform will remain inaccessible and our primary focus will remain containment and understanding the scope of the incident. See the memo here: lightning.ai/blog/oct-2026-i…
We know this disruption is serious. But protecting your data and workloads is simply too important to our team to risk.
We're here to help, don't hesitate to DM me if you need anything. 💜

Come say hi!
During GTC Berlin, Lightning AI is joining NVIDIA and @betahaus Berlin for AI Startup Compute Night.
We'll be on the partner panel talking GPU availability, infrastructure, and what it takes to get compute at every stage, from prototype to production.
Then, stick around for food, drinks, and networking with AI founders, builders, and technical leaders.
📍 Berlin | 🗓️ Oct 21, 6–9pm CEST
Space is limited. Reserve your spot now → luma.com/6bx2qu5m
Proud to partner with @nvidia as we secure the future AI frontier!
Today, with over 100 industry partners, we introduced the NVIDIA Open Agent Safety Platform, bringing together OpenShell and Sentry.
Artificial intelligence is extraordinary technology that will advance discovery, productivity, security, health, and prosperity for generations to come.
But its full promise can only be realized when people have confidence that AI is being built to be safe and deployed with wisdom and responsibility.
This is bigger than a single product. It's the beginning of an open ecosystem to build the trust layer for safe agent systems.
Together, we are building the foundation of the AI economy.
Trust and innovation are not in conflict. Safety is how trust is earned. We must build not only the most capable AI, but the most trusted AI, so that this extraordinary technology can realize its enormous promise for the world. nvda.ws/4hcoq7m
Hot take: Instinct is doing to ChatGPT what ChatGPT did to AI research. Way better interface for capabilities that have existed.

Congratulations!
Today, We proud to announce the release of Arcle V1 — a 5.84B unified omni foundation model bringing text, vision, document comprehension, and 24kHz speech into a single forward pass.
Open weights, offline-first, and optimized for edge compute. 🧵👇
#OpenSourceAI #MachineLearning
Excited to partner with our partners in the biotech space!
Proud to support this release with a ready-to-use Lightning Studio. Just open it up and start exploring the Chronos data, notebooks, and models. Get started for free go.lightning.ai/4dh26Ha
Controlled capitalism is a mood
We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so.
Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

August rewind
Another big month is in the books for Lightning:
We shipped a massive (200x faster data persistence) upgrade to Lightning Drive, started swapping some H100s → H200e, put Lighting VMs in early access, and opened reservations for our exclusive evening during AI Infra (limited spots are still available).
Here’s what shipped and where we’re headed next → go.lightning.ai/3UMP65K

Sonic-3.6 is now generally available.
In January we made a bet: stop tuning the existing paradigm, rebuild from the architecture up.

More data than open-source AI is taking share from OpenAI and Anthropic. Open source has gone from 28% token share to 62% token share @vercel over the last 2 months. Chart from @rauchg
Super impressive given that the sum of OpenAI and Anthropic accelerated in July. So net token/AI infra demand accelerated even more than the acceleration we saw at the frontier. And suspect Grok growing even faster than open-source and we saw some of this in the @tryramp data.
Open-source AI taking share is positive for AI infrastructure demand as it lowers margins at the model layer and an open-source token costs just as much compute to produce as a frontier token. Nothing about open-source AI inference is “free.”
Most likely end state IMO is that closed, frontier tokens are 60-90% of economic value but only 15 to 25% of tokens.
