Anthropic made Claude Opus 4.7 generally available on April 16, 2026, replacing Opus 4.6 as the primary API model. The release improves performance on complex, long-running coding and agentic tasks, raises the image input ceiling to 2,576 pixels on the long edge (~3.75 megapixels), and adds a new xhigh effort level for finer control over reasoning depth versus latency. Pricing is unchanged at $5/$25 per million input/output tokens; an updated tokenizer may increase input token consumption by 1.0–1.35× depending on content type.
