Claude Fable 5.1 на OpenRouter

anthropic/claude-fable-5-1 через OpenRouter key. List rates + credit markup. cache_control для caching; fallback — ваш.

Available 2026-09-02. Catalog anthropic/claude-fable-5-1. effort ok, temperature rejected. 30-day retention через Anthropic upstream.
Настройка
Четыре шага — третий ломает production.
- 1
OpenRouter account и key
openrouter.ai, credits, API key. USD credits с platform markup в rate card.
- 2
Namespaced model ID
model: anthropic/claude-fable-5-1. Bare ID может 404.
- 3
effort, без temperature
effort через provider params. No temperature/top_p/top_k — 400. Audit SDK templates.
- 4
Refusals в client
HTTP 200 + stop_reason refusal. Branch и свой fallback.
Подводные камни
Строка invoice, которую читают поздно.
Credits с platform markup
OpenRouter rate vs Anthropic direct — compare live rate cards перед production Agent volume.
No auto-failover на refusal
Refusals forwarded as success. models array или client fallback сами.
Caching требует cache_control
90% discount только с breakpoints. OpenAI-compatible clients часто omit.
30-day retention applies
OpenRouter не bypass ZDR blocker на Fable 5.1.
