COSMOS 3 LANDS IN DIFFUSERS, PYTORCH 2.12 BREAKS IP-ADAPTER TESTS

NVIDIA's unified world foundation model is now integrated into Diffusers, but the PyTorch randomness shift is forcing test rewrites across the stack.

Cosmos 3 [1] is shipping as a single Mixture-of-Transformers pipeline that consolidates world generation, physical reasoning, and action prediction into one forward pass, replacing the three-model approach from earlier releases. The IP-Adapter tests for Stable Diffusion are failing on PyTorch 2.12 [2] because torch.randn no longer produces deterministic outputs for the same seed, forcing engineers to patch pipeline-level noise generation directly and update expected output slices. Meanwhile, the CI infrastructure across transformers-test-ci is stabilizing with cache fixes [3] and branch ref corrections [4] to prevent lock file creation errors and git checkout conflicts on main pushes. The ai-reviewer tooling picked up performance improvements in git operations [5] while documentation cleanup continues across the board [6] [7] [8].
