Anthropic
Claude API
Anthropic's Claude line — three models split by capability and by writing style.

제품군 내 모델 수
The Claude models we serve split along two axes rather than one: Sonnet and Opus are the balanced and the most-capable tiers, while Fable is tuned specifically for long-form writing and narrative work. All three speak the OpenAI protocol here and all support prompt caching, with cached reads at a tenth of fresh input.

어떤 모델을 고를까
Claude Sonnet 5
The default. Coding, agentic workflows and everyday reasoning with text and image input, at a third of Opus's price.
Claude Opus 5
Complex reasoning, hard coding problems and long agentic runs where capability matters more than cost.
Claude Fable 5
Long-form writing and narrative work — the tier tuned for prose rather than for reasoning benchmarks.
장점
- A writing-specialised tier alongside the general ones, which most families do not offer.
- Prompt caching on all three, with cached reads at a tenth of the input price.
- Sonnet takes image input as well as text, at the lowest price in the line.
- OpenAI-protocol compatible, so existing client code works unchanged.
제한 사항
- Output tokens cost five times input across the line, so long generations are expensive.
- Cache writes are billed above fresh input, so caching only pays back on reuse.
- Fable is the most expensive tier per input token despite not being the most capable one.
