The Intelligent Systems Company. Co-evolving chips & intelligence.
🇬🇧 Sovereign AI is backing @IneffableLabs 🇬🇧 We can announce Sovereign AI has invested in Ineffable. Led by David Silver, Ineffable is building learning systems that can go beyond the limits of human knowledge, learning continuously to push the frontiers of science and technology.
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.
