Deep Test-Time Compute · 2026 Release

Alchemax-o3 Pro Reasoning

Engineered for the hardest problems in mathematics, autonomous software engineering, formal verification, and scientific discovery through tree-search test-time reasoning.

Deep Test-Time Compute 2026 Release

Architectural Overview

Alchemax-o3 Pro is trained via large-scale reinforcement learning over formal proof environments, compiler toolchains, and executable sandboxes. Before emitting a final answer, o3 Pro explores and verifies multiple reasoning trajectories, backtracking automatically when an intermediate hypothesis fails verification.

On SWE-bench Verified, GPQA Diamond, and frontier competition mathematics, Alchemax-o3 Pro establishes decisive new state-of-the-art marks—outperforming competing reasoning models while producing inspectable, audit-ready reasoning traces.

Key Capabilities & Technical Specifications

  • 89.2% autonomous resolution rate on SWE-bench Verified across multi-file production repositories
  • 96.7% accuracy on AIME 2026 and 88.4% on GPQA Diamond (PhD-level physics, chemistry, and biology)
  • Configurable reasoning effort budgets (Low, Medium, High, Exhaustive) via a single API parameter
  • Integrated formal proof checking for Lean 4, Rust borrow-checker verification, and SQL query validation
