Over a two-month period, contributed to the modular/modular repository by developing and optimizing features for the FLUX.2-dev pipeline, focusing on reducing inference latency and enhancing attention mechanisms. Leveraging Python, Mojo, and CUDA, refactored pipeline execution paths to move hot-path eager operations into compiled subgraphs, improving throughput and profiling for text-to-image generation. Introduced autotuning and metadata caching for cuDNN convolution, enabling dynamic algorithm selection and faster VAE decoding. Developed a dual ragged RoPE kernel with explicit position IDs, allowing more flexible graph compilation and robust attention integration. The work emphasized performance optimization, GPU programming, and deep learning pipeline development.

Mar 1, 2026March 2026 produced performance-focused features in modular/modular with tangible latency reductions and improved attention capabilities for FLUX.2. Key investments were in autotuning and caching for cuDNN convolution, and in a dual ragged RoPE kernel with explicit position IDs, enabling more flexible graph shapes and improved integration for FLUX.2-dev. These workstreams delivered more efficient GPU utilization, faster VAE decoding, and more robust attention paths, directly translating to faster inference and better scalability in production workloads.

Feb 1, 2026February 2026 — modular/modular: Flux.2-dev Pipeline Optimization for Text-to-Image Inference Latency. Implemented a pipeline-side refactor to move hot-path eager ops into compiled subgraphs and enhanced profiling controls for diffusion runs, resulting in a measurable latency reduction for 1024×1024 TTI with 50 denoising steps to ~15–16 seconds on a B200 GPU. Commit: 4d32760f25b5b223c3dfeb50c92011c2282b7581. Scope: no kernel changes; changes are designed to improve throughput and observability while preserving correctness. Impact: faster renders, higher throughput, better profiling, foundation for further optimizations.
