Model details

Strengths, weaknesses, and pricing notes

Strengths

  • Strong reasoning-focused capability
  • Useful for complex multi-step tasks
  • Good for high-stakes analysis

Best-fit scenarios: Reasoning-heavy tasks such as complex planning, deep analysis, and technical decision support.

Benchmark advice: Score chain-of-reasoning consistency and final-answer reliability separately.

Weaknesses

  • Can be slower on heavy prompts
  • Cost profile should be benchmarked for scale

Watch-out: Use strict validation in regulated or high-risk decision contexts.

Pricing notes

Reasoning-focused family; best for tasks where depth matters.
