During October 2025, Git Rover developed the Babybear GPU Prover feature for the scroll-tech/ceno repository, focusing on accelerating zero-knowledge proof generation using GPU resources. Leveraging C++, CUDA, and Rust, Git Rover implemented optimizations for proof creation, batch commits, and main/tower proofs, resulting in faster proof throughput and improved scalability for GPU-enabled workloads. The work included updating dependencies and internal type mappings to ensure compatibility and maintainability within the codebase. Integration with existing proof pipelines was validated, and related tests and documentation were updated to reflect the new GPU prover functionality, demonstrating depth in GPU programming and performance optimization.
