Enhanced reasoning model (Released: September 22, 2025)

Overview

Enhanced reasoning model focusing on "Agentic Reasoning" and "Formal Reasoning". Features a dual-path reasoning framework combining agentic tool use with formal reasoning capabilities. Built with DORA (Dynamic Orchestration for Asynchronous rollout) for asynchronous large-scale training.

Key Features

  • 64.5% token savings: Dramatically improved tool-call efficiency (from 19,653 tokens down to 6,965 in AIME25 tests)
  • Dual-path reasoning: Combines agentic tool use with formal reasoning
  • DORA training: Asynchronous large-scale training system
  • Enhanced efficiency: Cost-effective agentic scenarios
