About

GSD 2 is an AI software development framework designed to help teams move from simple prompting to a more structured, repeatable engineering process. The framework supports AI-assisted development by organizing work around specifications, context, execution, validation, and review. Instead of relying on isolated prompts, GSD 2 helps developers create clearer workflows that guide AI agents through planning, implementation, and quality checks. It is built for teams that want AI coding tools to operate with better direction, stronger traceability, and fewer ambiguous handoffs. The framework can help reduce drift between intended requirements and generated code by emphasizing persistent artifacts and human oversight. GSD 2 gives software teams a more disciplined way to use AI agents in real development projects.

About

Leanstral is an open-source code agent developed by Mistral AI specifically designed to work with the Lean 4 proof assistant. The model focuses on generating code while also formally verifying its correctness against strict mathematical or software specifications. Unlike traditional coding assistants, Leanstral integrates directly with formal proof systems to ensure that generated code satisfies defined logical requirements. Its architecture is optimized for proof engineering tasks and operates efficiently with sparse model parameters. Leanstral is released under the Apache 2.0 license, making it freely accessible for developers, researchers, and organizations to use and customize. The model is designed to operate within real-world formal repositories rather than isolated problem environments. By combining code generation with formal verification, Leanstral aims to reduce the need for manual human review in complex software and mathematical development.
