Why teams choose it

Long-context analysis
Helps teams summarize, compare, and extract insights from long documents without losing important nuance.
Document-heavy workflows
Useful where teams ingest PDFs, slides, audio, or long threads and need repeatable extraction—not one-off prompting.
Cost-efficient routing
Useful as part of a routing stack where cheap models handle drafts and confirmations and this tier handles genuinely hard passages.
