The Intelligent Systems Company. Co-evolving chips & intelligence.
incredibly bullish on the future of tech + AI in London. just to name a few: • OpenAI just announced (last week) that London will become its largest research hub outside San Francisco • Anthropic kicked off a 100+ person hiring spree across London and Dublin in 2025 • xAI set up shop in London in early 2025, based in X's former Piccadilly office, led by former DeepMind researcher Toby Pohlen • Microsoft hired 24+ researchers from Google DeepMind for its London AI hub • Google DeepMind announced its first automated research lab in the UK (opening 2026), focused on discovering new materials using AI and robotics • Perplexity committed £80M to expand London offices • Groq is opening its first UK data centre in London • Cursor chose London as its European HQ
Today we launched @CallosumAI. We are building the infrastructure where heterogeneous chips & intelligence co-evolve to solve the world's hardest problems. Today we present our first results. Across four large problem spaces, we break SOTA and deliver orders-of-magnitude improvements in capabilities, cost and speed: 12× cheaper deep context. New web SOTA with open-source, 3x cheaper and faster. 2.4× cache speedups. 1,767× faster tool calling. This is the worst our infrastructure will ever be. We do it by co-evolving heterogeneous chips and multi-agent intelligence - workflows aware of their hardware, models aware of their task graph, kernels aware of their output constraints.
