June 2026 | Affine Foundation/affine delivered a focused set of high-impact features and reliability improvements spanning ranking performance, miner lifecycle, data integrity, and scalable operations. Key features include persistent and display of model type in the Miner Ranking System, an asynchronous challenge state fetch and a background rank cache to significantly reduce latency; added Qwen3.6 miner support with refined reward distribution and test-friendly skip logic; enabled HuggingFace Xet downloads with retryable config fetch handling and state preservation on failures; introduced configurable admin CLI tools and a safe rotate-window workflow for champion rotations; and built a robust GPU endpoint autoscaler with lease renewal and improved handling for stale deployments. In addition, we fixed Miner Metadata Integrity to prevent accidental overwrites and hardened SSH container status parsing with unit tests, enhancing reliability across the system. These changes improve business value by accelerating ranking responses, enabling broader miner support, ensuring data integrity, and reducing operational costs through automated scaling and safer deployments.
