Autonomous LLM Post-Training with Tunix on TPUs

Google Developers detailed Tunix, an autonomous workflow designed to streamline LLM post-training on TPU infrastructure. By defining objectives and constraints within a single Markdown specification, the system automatically coordinates fine-tuning runs, evaluation benchmarks, and parameter sweeps without requiring constant human oversight. It turns what was previously an iterative, hands-on alignment routine into a scheduled, background compute cycle.
