BFS-Prover V2 7B
BFS-Prover V2 7B is the smaller Lean 4 tactic generator in the V2 release.
Model design
This checkpoint starts from Qwen2.5-Math-7B. Its training sources include Mathlib, Lean repositories and autoformalized mathematics. It expects a tactic state followed by the same three-colon marker used by the larger version.BFS-Prover V2 7B official model card
Practical use
Practical guidance. Use the smaller model to measure the trade-off between model size and search breadth. Keep the Lean environment and theorem set fixed for a meaningful comparison.
