Claude Opus 4.7 is Anthropic's most capable generally available model at its April 2026 launch, positioned for complex reasoning and long-running agentic coding. It carries a 1M-token context window, 128K max output tokens, and adaptive thinking—an upgrade to extended thinking that lets the model decide how much to reason based on task complexity and a selected effort level. It also adds high-resolution multimodal vision, improving accuracy on charts, dense documents, and screen UIs.

Compared with its predecessor Claude Opus 4.6, Anthropic describes a step-change in agentic coding and long-horizon autonomy. On Anthropic's reported CursorBench, Opus 4.7 clears 70% versus 58% for Opus 4.6, and the company cites a 14% gain on complex multi-step workflows at fewer tokens with roughly a third of the tool errors. It also introduces a new "xhigh" effort level between high and max.

The Opus 4.7 generation includes a low-latency variant, Claude Opus 4.7 Fast, alongside the standard model. Anthropic later released Claude Opus 4.8, which builds directly on Opus 4.7 and, per Anthropic, reduces wasted thinking tokens on mixed workloads and improves tool triggering and post-compaction long-context quality.

Opus 4.7 targets autonomous agents, multi-step coding, and vision-heavy pipelines, sitting between Opus 4.6 and Opus 4.8 in Anthropic's lineup.
