Description

Leanstral 1.5 is a model licensed under Apache-2.0, designed for effective proof engineering in Lean 4, aimed at enhancing the capabilities and accessibility of formal verification. It boasts a total of 119 billion parameters, with 6 billion of them being active, marking a significant improvement in performance for tasks such as theorem proving, agent-based proof engineering, and the verification of practical code. The development of Leanstral 1.5 involved a comprehensive three-stage training process, which included mid-training, supervised fine-tuning, and reinforcement learning utilizing CISPO. In a multiturn environment, the model is tasked with receiving a theorem statement, submitting a proof, and refining its approach based on feedback from the Lean compiler until the proof is either successfully compiled or the available resources are depleted. In the code agent setting, Leanstral functions similarly to a developer navigating a raw filesystem, allowing it to edit files, execute bash commands, and interact with the Lean language server to monitor goals, errors, and type information in real time. This innovative approach not only streamlines the proof engineering process but also significantly enhances the user experience in formal verification tasks.

Description

Lightning Rod is an innovative AI platform that streamlines the process of converting chaotic, unstructured real-world information into polished, production-ready datasets and specialized AI models without the need for manual labeling. This platform allows users to create high-quality, citable question-answer pairs derived from various sources, including news articles, financial documents, and internal records, effectively transforming raw historical data into organized datasets suitable for supervised fine-tuning or reinforcement learning applications. Utilizing an agent-driven workflow, users can articulate their objectives, and the system autonomously collects relevant sources, formulates questions, evaluates outcomes based on actual events, and incorporates contextual grounding before model training. A significant advancement of this platform is its “future-as-label” approach, which leverages real-world results as training signals, enabling AI systems to learn directly from authentic outcomes at scale rather than depending on synthetic or manually curated data. This capability not only enhances the accuracy of AI models but also improves their adaptability to dynamic real-world scenarios. With Lightning Rod, organizations can harness the power of their data more effectively than ever before.
