Where it fits
- High-volume, cost-sensitive work — at $0.23/1M output it sits in the cheapest quarter of tracked models.
- Input-heavy jobs like summarization and RAG — input is cheap at $0.075/1M, and these read far more than they write.
Watch for
- Priced from OpenRouter's routed market, not a first-party list price — availability and rate can shift without notice.
- Text-only — no image, audio, or file input.
These notes are derived from price, context and modality — structural facts, not measured quality. Measured cost-to-finish-a-task lives on the real-cost index.

How to read Ling 3.1 Flash's pricing
Two numbers decide most of the bill: $0.075/1M for input (everything you send — prompt, context, attachments) and $0.23/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 3.0× the input rate here, so the shape of your workload — how much it reads versus writes — matters as much as the headline figure. This row is OpenRouter's routed market price; it can move as providers and routing change.
