Ring-2.5-1T

Ring-2.5-1T is the world's first open-source trillion-parameter reasoning model based on hybrid linear attention architecture. It introduces a high-ratio linear attention mechanism that reduces memory access overhead by over 10× and increases generation throughput by more than 3× for sequences exceeding 32K tokens, making it particularly suitable for deep reasoning and long-horizon task execution.
