Reasoning Language Model
Model assetModel ServingModelsarc:ReasoningLanguageModel
A language model tier trained to emit extended internal reasoning, trading markedly higher token consumption for accuracy on complex tasks.
Responsibility. Provides high-accuracy, token-intensive inference for complex reasoning queries.
Also known as: Reasoning model, Expensive reasoning model
Variant of Foundation LLM abstract
When to choose. Choose for complex queries where accuracy improvements justify the substantially higher token cost.

Quantitative guidance
As stated by the sources; verify before use.
- Some open-source reasoning models use 1.5x-4x more tokens than closed systems; 10x or more on basic knowledge questions (Ch5.2).
- Reasoning model combined with ToT may consume ~15x the tokens of CoT with a base model (Ch5.2).
