Ant Group has open-sourced the world's first thinking model based on hybrid linear architecture with trillion parameters, Ring-2.5-1T.

In terms of generation efficiency, Ring-2.5-1T has reduced memory access scale by more than 10 times and increased generation throughput by over 3 times compared to the previous generation model in 32K+ long text generation scenarios. In terms of deep thinking capabilities, the model has achieved gold medal-level results in self-tests for the International Mathematical Olympiad (IMO 2025) and the Chinese Mathematical Olympiad (CMO 2025) (IMO 35 points, CMO 105 points).

Additionally, it can adapt to intelligent agent frameworks like Claude Code and personal AI assistants like OpenClaw, supporting multi-step planning and tool invocation.
