Higgsfield Tests Claude Opus 5.5 and GPT-6 Sol on a Houdini Chainmail Workflow

Higgsfield has turned model-release week into a hands-on test of AI agents inside SideFX Houdini, showing Claude Opus 5.5 and GPT-6 Sol being used to build chainmail, set up node networks, test collisions and refine link motion. The demo is less a product launch than a signal that frontier models are being evaluated on whether they can operate specialist creative software through iterative tool work, not just write code or text.
