## Introduction
We present a fine-tuned model for formal verification tasks. It is fine-tuned in five formal specification languages (Cog, Dafny, Lean4, ACSL, and TLA) on six formal-verification-related tasks:
- **Requirement Analysis**: given requirements and description of the verification or modeling goals, decomposing the goal into detailed verification steps
- **Proof/Model Generation**: given requirements and description of the verification or modeling goals, writing formal proofs or models that can be verified by verifier/model checker.
- **Proof segment generation**
- **Proof Completion**: complete the given incomplete proofs or models
- **Proof Infilling**: filling in the middle of the given incomplete proofs or models
- **Code 2 Proof**: (Currently only support for ACSL whose specification is in form of code annotations) given the code under verification, generate the proof with the specifications
