Claude Opus 4.7

Anthropic released Claude Opus 4.7 with improved coding capabilities, higher-resolution vision, and a new reasoning level. The company publicly acknowledged the model underperforms its unreleased Mythos system, which remains restricted due to safety concerns.

Anthropic has released Claude Opus 4.7, its most powerful generally available model, though it scores lower than the company's Mythos Preview model on every evaluation. The company intentionally reduced Opus 4.7's cybersecurity capabilities during training as it tests safety measures before releasing more powerful models.

Anthropic has released Claude Opus 4.7, its latest generally available AI model focused on advanced software engineering. The model shows improvements in handling complex coding tasks with less supervision, enhanced vision capabilities, and better instruction following, while introducing a new tokenizer that increases token usage by 1.0-1.35× depending on content type.

Anthropic has released Claude Opus 4.7, the latest version of its flagship Opus family designed for long-running, asynchronous agent tasks. The model features a 1 million token context window and costs $5 per million input tokens and $25 per million output tokens.

Anthropic released Claude Opus 4.7, a new model that the company says is 'broadly less capable' than its most powerful offering, Claude Mythos Preview. The model includes automated safeguards that detect and block prohibited or high-risk cybersecurity requests.

Anthropic released Python SDK v0.96.0 on April 16, 2026, adding support for Claude Opus 4-7, a new flagship model. The update introduces token budgets for cost management and user profiles for personalized interactions.
