After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

“If all AI is built on one platform, we'll only have a certain envelope of future outcomes. Whereas if the future of AI is built on a broad population of platforms by a broad population of users and organizations and nations, we're much more likely to experience the benefit of this technology rapidly and avoid the risks.” Andy Hock and @DanAkarca of @CallosumAI on the vision behind the new Cerebras-Callosum partnership.

“We're in the early stages now of this Cambrian explosion. What are the boundary cases where we want certain tasks on certain models on certain silicon? We’re making that programmable. This is where all the frontier performance is going to come from.” Proud to launch our new partnership between @CallosumAI and @cerebras. Thanks to Andy for a great conversation!

"You now have new surface area to expose the benefits of the silicon in new ways. We had some really amazing results when doing this over a huge amount of different silicon. Cerebras was unbelievably good. We could actually not only improve the speed by a significant amount in these long-context reasoning problems, we also found that we could also make them very cost-effective because we're being efficient with the tokens." — @DanAkarca, co-founder of @CallosumAI, in conversation with our Andy Hock on the new Cerebras-Callosum partnership.

Heterogeneous compute is becoming the standard for AI infrastructure. @CallosumAI just announced their global partner network. d-Matrix is proud to be part of the US ecosystem alongside @Intel, @AMD, and others. No single chip does every job well. The right workload deserves the right silicon. Corsair was built for exactly this: purpose-built for inference, with the memory bandwidth and efficiency to make AI systems practical instead of unsustainable.

Very exciting times for @CallosumAI + @Cerebras 🧠
Faster agent loops. New systems that were not practical before. Cerebras inference is coming to @CallosumAI APIs. 🟧

We are proud to announce our first major partnership with @CerebrasSystems. Their wafer-scale engines are delivering inference at speeds that are hard to comprehend. Composed within Callosum's platform, that speed becomes something entirely new: heterogeneous multi-agent systems

.@UKSovereignAI has made its first-ever investment, backing British AI infrastructure company @CallosumAI in a $100M seed round with US investor @DCVC and others 🤝 Proof of the UK's £1.1B (~$1.4B) AI infrastructure investment, and what's on offer for North American businesses.
A massive congratulations to @CallosumAI on raising a $100m seed round. Callosum was our first investment. We backed @achterbrain, @DanAkarca and the team because they’re building a foundational piece of the next generation of AI infrastructure. It’s brilliant to see that conviction shared by leading investors.

Congrats to the @CallosumAI team on the $100M seed round! 🎉 We’re excited to be partnering around a shared vision for heterogeneous AI compute, using the right chip for the right workload. As inference becomes more demanding, we're especially excited to power the fast, premium decode layer with SambaNova. 🦾

Really excited to share some of what I have been working on!
We’re excited to release Tailored Inference, unlocking new frontiers in speed and cost-efficiency by optimising inference to the right models, algorithms and chips. By leveraging the inherent structure of inference workloads, it allows us to decompose them to discover new solutions with improved cost-efficiency for our partners.

In these critical workloads, we found solutions built around closed-source frontier models are typically slow and/or expensive, prohibiting fast detection of threats at scale. By discovering new fast and cheap solutions, it allows both rapid and frequent detection, enabling a new level of capability.

Two years ago, we backed @DanAkarca and @achterbrain with seed funding to explore biologically-inspired neural networks. Since then, they have founded @CallosumAI, which has since become a member of our Scaling Inference Lab. Today, Callosum have announced a $100M seed round to rethink how we compute for the next chapter of AI. Huge congratulations to Dan, Jascha and the team. We’re excited to see where you take it next.
