Established

Integrates natively into Lean 4 via FFI with CTranslate2 for local inference, while supporting remote model execution through configurable APIs. Provides three core tactics—`suggest_tactics` for LLM-generated tactic proposals, `search_proof` for multi-tactic proof search combined with aesop, and `select_premises` for retrieval-based premise selection—all backed by pre-trained models from LeanDojo or custom user-defined models.
