What is
Reasoning Model?
An LLM trained or post-trained to perform multi-step reasoning, often using extended hidden thinking tokens.
Definition
Reasoning models (OpenAI o1/o3, Claude with extended thinking, DeepSeek R1) explicitly allocate compute to a hidden reasoning step before producing a final answer. They excel at math, code, and multi-step logic. The trade-off is latency and cost — a reasoning model can take 10x longer than a standard chat model.
Example
A complex SQL generation task: a reasoning model thinks through joins, filters, and edge cases before emitting the final query.
How Vedwix uses Reasoning Model in client work
Used for hard tasks where correctness matters more than latency. Always paired with strong evals.
