LLMs as Copilots for Theorem Proving in Lean

Why this job: works in the areas we cover, but does not say which job it does

What it does

Lean Copilot allows large language models (LLMs) to be used natively in Lean for proof automation, e.g., suggesting tactics/premises and searching for proofs. You can use our built-in models from LeanDojo or bring your own models that run either locally (w/ or w/o GPUs) or on the cloud.
