Overview & Capability
Deliberate chain-of-thought models designed to solve complex multi-step problems in mathematics, scientific research, and complex software engineering.
Key Highlights
- Produces step-by-step verified reasoning chains before outputting code or proofs.
- Competitive programming performance and doctoral-level science benchmarks.
- Autonomous debugging across complex multi-file codebases.
