Recursive (formally Recursive Superintelligence) is an AI research lab building systems that improve themselves — AI that makes better AI. The core product is the "Eureka Machine," an automated research system that designs experiments, proposes new model architectures, writes optimized GPU code, and runs training pipelines with minimal human direction. Humans oversee and can halt the process. The lab's first public output is Flint, a 40-billion-parameter, open-weight, mixture-of-experts coding model released October 21, 2026 — built from scratch in under four months, primarily by the Eureka Machine itself. Flint runs locally on a laptop, avoids cloud API fees, and scores 89.7% on SWE-bench Pro v2. The longer-term plan is to extend the self-improvement loop beyond AI research into broader scientific domains. The company was founded in 2025 by Richard Socher (former Salesforce Chief Scientist) and Tim Rocktäschel (former Google DeepMind), with talent drawn from OpenAI, Meta AI, Uber AI, and DeepMind. Offices in San Francisco and London.
