Reasoning Model
Definition
Reasoning models are designed for more complex multi-step problem solving.
A non-uniformly standardized model category for language models optimized for multi-step problem solving and additional computational effort during inference.
Simply explained
A model uses additional computation to process a task in multiple steps.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
A model breaks down a complex planning task and verifies intermediate results before providing an answer.
Limits and pitfalls
- Do not equate the label "Reasoning" with reliable logic, correct intermediate steps, or awareness, and do not externally verify results based on the task.
Origin & history
Chain-of-Thought prompting and research on additional inference effort preceded specialized models marketed as Reasoning Models. The designation and technical implementation vary by provider.
Use in mid-sized companies
- Possible application: A model breaks down a complex planning task and verifies intermediate results before providing an answer.
