EvoLink rates use your current group. The struck-through OpenAI official rate uses the same model, token role, and context multiplier for an exact comparison.
GPT-5.6 API — Sol, Terra, Luna
하나의 EvoLink API 키로 세 가지 GPT-5.6 등급을 사용하세요. 최고 성능의 Sol, 균형 잡힌 Terra, 빠르고 경제적인 Luna 중에서 선택할 수 있습니다.
Four-part prompt caching
Uncached input, cache reads, cache writes, and output are settled separately from the final usage object. Cache writes are not charged again as ordinary input.
Long-context threshold
At more than 272K prompt tokens, input and both cache roles use 2x rates while output uses 1.5x rates for the entire request.

GPT-5.6 API - FAQ
Which model IDs are available?
Use gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna. A generic gpt-5.6 alias is not available.
How is cached input billed?
Cache reads and cache writes are separate token segments. Neither segment is billed again as ordinary input.
When do long-context rates apply?
When total prompt tokens exceed 272,000, the whole request uses the long-context multipliers shown in the pricing table.
