Recursive launches laptop-ready coding model built largely with AI
AI startup Recursive released Flint, a free coding model that can run on a laptop.
The company says its Eureka Machine helped build nearly every part of the model in under four months, with people overseeing the work.
Flint is an early test of recursive self-improvement, the idea that AI can help create better AI.
The model is available to download under an open-source license, and running it locally lets developers work offline, keep code on their own computers and avoid cloud usage fees.
Recursive says Flint performed well on coding tests, while an early reviewer found it fast and capable; the company also says it needs more guidance than leading paid assistants.
The current system remains limited and human-supervised, but the wider idea is controversial because some experts fear AI could improve beyond human control.
Recursive says it wants the Eureka Machine to reach fuller self-improvement, with people able to stop the process if needed.
Recursive released Flint, a free coding model designed to run on a laptop, and says AI helped build it.
The company says its Eureka Machine contributed to nearly every stage of development, enabling a small team to build Flint in under four months.
Flint has 40 billion parameters but uses 2.5 billion for any given task, and is available under the Apache 2.0 license.
Recursive says the model performed strongly on coding benchmarks, while Wired’s reviewer reported positive results in hands-on tests.
The launch has renewed debate over recursive self-improvement, which some experts fear could lead to AI escaping human control.

Risk of recursive self-improvement
Experts concerned about recursive self-improvement
Some experts fear AI that improves itself could escape human control and threaten people.
Recursive
Recursive considers those fears more science fiction than reality.
Regulation
Experts concerned about recursive self-improvement
Some proposed bills in Congress would ban recursive self-improvement.
Recursive
Recursive says legislation to prevent it would unnecessarily impede progress.
Recursive says a small team built Flint with help from the Eureka Machine.
A researcher quit Anthropic and warned that AI advances, including recursive self-improvement, could lead to human extinction within a few years.

What people are saying
Nearly every aspect of the entire model pipeline was actually done and improved upon by AI
We hope that this shows people that indeed we have all the steps in place
