## What changed

Two new models in the Supercomputer selector. GPT‑5.6. OpenAI's most powerful model to date: breaks complex pipelines into subtasks, holds more steps in mind at once, and stays on track through long multi-stage runs. Pick it for the most demanding work where depth matters more than speed. Grok 4.5. xAI's new model with a strong engineering base: noticeably faster, well balanced between speed and quality, and cheaper at comparable quality on most technical tasks, a solid default for everyday pipelines. To get started: pick GPT‑5.6 or Grok 4.5 in the Supercomputer model selector.
