doubleAI says its Maxwell code execution model made LTX-2.5 generate 4K video nearly 2x faster

doubleAI says Maxwell, its code execution model that rewrites a running program's binaries for the exact machine and data without changing the source code, cut LTX-2.5's 4K video generation from 250 seconds to 134 seconds per clip on two NVIDIA B200 GPUs, a 1.87x speedup with the same output. It says Maxwell made more than a dozen changes to LTX's already optimized pipeline, from how work is split across tiles and GPUs down to edits inside individual kernels, and moved CPU work onto the GPU so the pipeline no longer depends on host CPU speed. The figures are doubleAI's own.
