OpenRouter now serves Anthropic Claude Opus 4.7 and a Fast mode via one API, bringing 1M context and better long-running agent behavior.
Opus 4.7 is built for asynchronous agents and improves multi-step reliability and coherence across long sessions. It’s listed at $5/M input and $25/M output tokens on OpenRouter.
A Fast variant trades higher cost (6x) for speed, and “Latest” endpoints for Sonnet (1M context) and Haiku (200K) simplify upgrades. See the Opus 4.7 migration guide for switching from 4.6.
You can upgrade agent pipelines to Opus 4.7’s 1M context and better step reliability without changing providers or auth.
Fast mode offers lower latency when SLAs require it, but forces a clear cost trade-off.

Migrate a representative 4.6 workflow using the guide; measure output drift, tool-use consistency, and long-session recall.
Legacy codebase integration strategies...
- 01.
Swap model IDs in OpenRouter and add tiered fallbacks (Sonnet/Haiku) without client rewrites; enforce budget caps and retries.
- 02.
Update token accounting, timeouts, and dashboards for 1M contexts and 6x Fast pricing; watch for longer streams blocking workers.
Fresh architecture paradigms...
- 01.
Design agents around 1M-token windows and async execution; move heavy tasks off request threads to jobs/queues.
- 02.
Adopt a routing policy: Opus 4.7 for complex steps, Sonnet/Haiku for cheap pre/post-processing to manage spend.
