Max Tokens
Definition
A token limit restricts the tokens generated by a model call according to the rules of the respective API.
An upper limit on the number of tokens a model is allowed to generate in a single call; parameter name and counting method are API-specific. Depending on the API, internal reasoning or formatting tokens may also count; the limit does not guarantee a specific visible response length.
Simply explained
Like a limited response budget; depending on the service, invisible reasoning steps also consume part of it.
Why it matters in practice
Helps realistically assess model quality, limits, and technical decisions.
Example from business
An extraction process limits the output to 800 tokens and checks completeness separately.
Limits and pitfalls
- Equating tokens with words or confusing context window and output limit.
Origin & history
Input and output limits are operational parameters of language models; specific names like max_tokens or max_output_tokens depend on the API.
Use in mid-sized companies
- Possible example: A development team sets an output limit for an extraction call. It checks API counting method, abort status, and completeness, and plans how to handle truncated results.
