## About Claude Opus 4.7

Claude Opus 4.7 is a flagship language model from Anthropic, released on April 16, 2026 as the successor to Claude Opus 4.6. Anthropic aimed it at advanced software engineering: on the company's 93-task coding benchmark it resolved 13 percent more tasks than Opus 4.6, including four that neither Opus 4.6 nor Sonnet 4.6 could solve. It shipped across the Claude apps, the API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry on day one.

The 4.7 release brought two structural changes to the Opus line: a new xhigh effort level between high and max for finer control over reasoning depth, and a new tokenizer that changed how text maps to tokens. On artifio.ai it sits in the same catalogue as 100-plus other models, paid per generation with no per-model subscription.

## Features

- Text and reasoning model with image input; reads images up to 2,576 pixels on the long edge, about 3.75 megapixels and more than three times the prior ceiling.
- 1M-token context window and 128k-token maximum output.
- Adds an xhigh effort setting between high and max, trading longer reasoning for latency on hard problems.
- Adaptive thinking is the only thinking mode; manual extended-thinking budgets from Opus 4.6 are not supported.
- File-system-based memory for work that spans multiple sessions.
- Training data through January 2026.

## What people use it for

- Hard, long-running software engineering tasks; Anthropic reported users handing over their most difficult coding work.
- Reading technical diagrams, chemical structures, and other detail-dense images at high resolution.
- Finance and legal document work, two domains Anthropic called out as improved.
- Multi-session projects that need persistent memory between conversations.

## Reported strengths

- 13 percent higher resolution rate than Opus 4.6 on Anthropic's 93-task coding benchmark.
- Follows instructions more literally than earlier Opus models, which makes agent harnesses more predictable.
- Devises ways to verify its own outputs before reporting back on complex tasks, per Anthropic's launch notes.
- Substantially sharper vision than any earlier Claude model at release.

## Reported limitations

- Refusal behavior drew criticism: Claude Code users filed 35 reports of false-positive refusals in April 2026, the highest monthly count on record, and some users judged it worse than Opus 4.6 for that reason.
- The new tokenizer makes the same text consume roughly 1.0 to 1.35 times as many tokens, and Anthropic advised re-tuning existing prompts.
- Custom temperature, top_p, and top_k values return errors; sampling cannot be tuned.
- Anthropic itself called it less broadly capable than its limited-release Mythos Preview, and Opus 4.8 superseded it six weeks later.
