AI models for text and reasoning

Choose the capability your text requires

Define whether you need an open response, a faithful transformation or a decision within fixed categories. Increasing reasoning can change time and cost, but does not guarantee correctness. The context window describes processing capacity; it does not establish uniform attention to every document or replace retrieval and verification strategies.

A concrete example

When summarizing a long contract, check that exceptions, dates and cross-clause references survive. When classifying queries, examine category errors and out-of-scope responses. The same aggregate average may hide very different failures in those applications.

What to check

Evaluate texts in the language and length you will use, including incomplete or conflicting documents. Record version, parameters and tools. Distinguish a plausible answer from one supported by the supplied material, and measure the human work needed to correct it.
