Pricing
Tiers are determined by the input context length of each request; Tune and Pro share the same tiered prices.
| Input context | Input | Output | Cache read | Cache write |
|---|---|---|---|---|
| ≤ 272K tokens | $0.2 | $1.2 | $0.02 | $0.25 |
| > 272K tokens | $0.4 | $1.8 | $0.04 | $0.5 |
Capabilities
GPT-5.6 Luna scored 80 overall, performing well — a fast, cost-efficient member of the GPT-5.6 family. It stands out in general knowledge (93%), long-context handling (88%) and hallucination control (87%), staying accurate over extended documents at a fraction of flagship cost, which suits translation, scriptwriting and e-commerce copy at volume. Comparatively, agent collaboration (61%) is weak; complex tool workflows exceed its reach. High-volume content tasks are where the economics shine.
