About
Leanstral 1.5 is an Apache-2.0 licensed model for practical proof engineering in Lean 4, built to make formal verification more powerful and accessible. With 119B total parameters and only 6B active parameters, it delivers a major performance upgrade for theorem proving, agentic proof engineering, and real-world code verification. Leanstral 1.5 was trained through a three-stage process: mid-training, supervised fine-tuning, and reinforcement learning with CISPO. In the multiturn environment, the model receives a theorem statement, submits a proof, gets Lean compiler feedback, and refines its approach until the proof compiles or the budget is exhausted. In the code agent environment, Leanstral works like a developer in a raw filesystem: it edits files, runs bash commands, and uses the Lean language server to inspect goals, errors, and type information in real time.

About
Theorem is a post-trade processing and data management solution that delivers aggregated reporting, trade workflow, matching / affirmation, and data movement, all in an online portal that requires no local install or technician to get started. Use Theorem to connect data collected from brokers, exchanges, and trading systems or your own internal systems and manage it according to your specific needs. Since there’s no heavy install, leverage the entire platform for a complete solution or simply choose what you need now. The moment a trade is executed, Theorem ensures accurate post-trade processing by allocating trades and performing trade matching against executing and clearing counterparties. Theorem harmonizes data, analytics, and other insights across brokers, accounts, and portfolios, offering you access to actionable insights while providing your stakeholders with advanced analytics and easily understood risk reports.
