Top 10 Open-Source Reasoning Models

Clarifai: the question is not 'Can AI do this?' but 'How well, at what cost?'. Reasoning LLMs generate intermediate steps before outputting answers. 2025 benchmarks show specialized reasoning models rival proprietary systems on math, logic, and tool-use tasks.

For developers: don't benchmark on MMLU alone. Ask if your task needs multi-step planning. Reasoning models have higher latency but far superior accuracy in complex agent workflows.
