CudaForge: Mimicking Human Expertise for Kernel Optimization
CudaForge's core strength lies in its ability to emulate the iterative process of human CUDA experts. This involves a two-agent LLM system—a Coder for generating and refining kernels, and a Judge for evaluating and providing targeted feedback—all informed by critical hardware metrics. This structured approach ensures efficiency and accuracy, avoiding the "blind exploration" common in other automated methods.

These results highlight CudaForge's ability to drive significant performance improvements, making it a critical tool for enterprises looking to maximize their GPU resource utilization for AI development.
Unmatched Cost-Efficiency for Enterprise AI Development
Traditional kernel optimization is expensive, demanding significant computational resources and expert developer time. CudaForge drastically reduces these costs by offering a training-free workflow, targeted hardware feedback, and a lightweight operational model.

Average API Cost per Optimized CUDA Kernel with CudaForge
Compared to existing agentic methods that can incur up to $5 per kernel and require 6 H100 GPU hours, CudaForge completes optimization in approximately 26.5 minutes on a single RTX 6000 GPU at a fraction of the cost. This efficiency is driven by:
Targeted Hardware Feedback: The Judge agent uses Nsight Compute (NCU) metrics to diagnose bottlenecks precisely, guiding the Coder to optimal solutions without blind exploration.
Selective NCU Metrics: Instead of profiling an overwhelming full metric set, CudaForge focuses on a curated subset of 24 critical NCU metrics, shortening profiling time and reducing input token length for LLM queries.
Lightweight Memory Design: Coder and Judge agents operate with current-round information only, avoiding context redundancy, reducing computation overhead, and lowering API costs.
This cost-effectiveness makes high-performance CUDA kernel optimization accessible and scalable for enterprise-level AI initiatives, yielding faster development cycles and reduced operational expenses.
Robust Generalization Across Diverse Hardware and Models
CudaForge's design ensures exceptional adaptability, performing consistently across various GPU architectures and large language models. This robustness is crucial for enterprise environments with heterogeneous hardware infrastructure and evolving AI model landscapes.

Correctness Rate Across A100, RTX 6000, 4090, 3090 GPUs
By explicitly incorporating GPU specifications and NCU profiling into its feedback loop, CudaForge tailors optimizations to the specific target hardware at inference time, eliminating the need for retraining for different environments. Furthermore, its agent-based workflow allows it to seamlessly integrate with and benefit from various advanced LLM backbones (e.g., GPT-5, Claude-Sonnet-4, GPT-OSS-120B), demonstrating its foundational strength beyond a specific model.
Case Study: CrossEntropyLoss Optimization Journey
In a detailed 10-round optimization of the CrossEntropyLoss task, CudaForge showcased its expert-like diagnostic and refinement capabilities:
Early Optimization: In Round 2, identifying 23.7% barrier stalls, the Judge recommended replacing shared-memory reduction with warp-level shuffles, boosting speedup from 1.66x to 2.42x by reducing synchronizations.
Critical Correction: Round 5 addressed a numerical mismatch due to an uninitialized variable, with the Judge providing a precise fix: broadcasting the variable via
_shfl_sync.Advanced Refinement: In Rounds 6 & 7, CudaForge tackled persistent global-memory latency (65-71% long-scoreboard stalls). The Judge advised reducing per-thread registers and buffering logits in shared memory, ultimately increasing speedup from 3.436x to 3.762x.
This iterative, hardware-feedback-driven process highlights CudaForge's stability and ability to achieve significant, targeted performance gains, emulating the decision-making of a seasoned human engineer.
