The Eureka Machine automated most of the model’s development, letting a small team ship it in under four months.

Recursive released Flint on Wednesday, a free coding model that runs directly on a laptop. The company says its automated research system, the Eureka Machine, handled nearly every step of development, letting a small team build the model from scratch in under four months.

Recursive emerged from stealth in May with $650 million in funding at a $4.65 billion valuation, backed by GV, Nvidia, and AMD Ventures. CEO Richard Socher, Salesforce’s former chief scientist, leads the company, which is testing the contested idea that AI can improve itself.

Because Flint runs on a user’s own machine rather than cloud servers, developers work offline, keep code private, and skip the per-token fees that hosted AI services charge. The model is free on Hugging Face under the Apache 2.0 license and activates just 2.5 billion of its 40 billion parameters per task.

Recursive acknowledged that Flint needs more guidance than big paid coding assistants and suggests splitting large tasks into steps. The company’s larger test is whether the Eureka Machine can push recursive self-improvement past a laptop-scale coding model.

What matters

• Flint is a free mixture-of-experts model that runs offline on a laptop with 40 billion parameters.
• Local execution keeps code private and avoids per-token cloud fees that coding assistants charge.
• Watch whether Recursive’s Eureka Machine can push self-improvement beyond a laptop-scale coding model.
