# claude-opus-4-7 — API, Pricing & Context Window

Run Anthropic's claude-opus-4-7 on Vivgrid: a frontier coding model with a 1M-token context window, the Messages API, and geo-distributed acceleration.

`claude-opus-4-7` is a frontier-class Opus model and one of the strongest available choices for agentic coding and complex reasoning. It combines a **1M-token context window** with a recent knowledge cutoff, served on the **Messages API** (`/messages`).

On Vivgrid, `claude-opus-4-7` is geo-distributed across **AMER, EMEA, and APAC**, giving Claude Code-style agents low-latency access through a single unified API key.
